Using Modern C++ - stepping up to C++14/17

C==+==14 is now fully implemented by the major suppliers. The C==+==17 ISO standard has just become official any day now and most of its features are already shipping. The shape of C==++==20 is under active discussion and early versions of some potential new features are already available.

This talk will consider the implications for the direction of C==++==, potential guidelines and techniques for using the new features, and the inevitable problems of applying new features to old code bases. We will pay special attention to features that can make a significant difference to developers by simplifying programming or increasing performance.

Localized Surface Plasmon Induced Position-Sensitive Photodetection in Silicon-Nanowire-Modified Ag/Si

By Chunlian Mei, Shuai Liu, Xu Huang, Zhikai Gan, Peiqi Zhou, Hui Wang from Small. Published on Sep 22, 2017.

Surface plasmon-based approaches are widely applied to improve the efficiency of photoelectric devices such as photosensors and photocells. In order to promote the light absorption and electron–hole pair generation in devices, metallodielectric nanostructures are used to boost the growth of surface plasmons. Here, silicon nanowires (SiNWs) are used to modify a metal–semiconductor structure; thus, Ag/SiNWs/Si is manufactured. In this system, a large increased lateral photovoltaic effect (LPE) is detected with a maximum positional sensitivity of 65.35 mV mm−1, which is ≈53-fold and 1000-fold compared to the conventional Ag/Si (1.24 mV mm−1) and SiNWs/Si (0.06 mV mm−1), respectively. It is demonstrated that localized surface plasmons (LSPs) contribute a lot to the increment of LPE. Furthermore, through the surface-enhanced Raman scattering spectra of rhodamine-6G and finite-difference time-domain simulation, it is illustrated that silver-coated SiNWs support strong LSPs. The results propose an enhancement mechanism based on LSPs to facilitate the photoelectric conversion in LPE and offer an effective way to improve the sensitivity of photodetectors.

Sensitivity is one of the main technical specifications of position-sensitive detectors. However, weak light absorption and low photoelectric conversion are two limitations to obtain prominent sensitivity. Based on localized surface plasmon, a large enhanced lateral photovoltaic effect is detected in a silicon nanowire-modified metal–semiconductor structure. Thus, a high position-dependent sensitivity is achieved in millimeter range.

Flexible Broadband Graphene Photodetectors Enhanced by Plasmonic Cu3−xP Colloidal Nanocrystals

By Tian Sun, Yongjie Wang, Wenzhi Yu, Yusheng Wang, Zhigao Dai, Zeke Liu, Bannur Nanjunda Shivananju, Yupeng Zhang, Kai Fu, Babar Shabbir, Wanli Ma, Shaojuan Li, Qiaoliang Bao from Small. Published on Sep 22, 2017.

The integration of graphene with colloidal quantum dots (QDs) that have tunable light absorption affords new opportunities for optoelectronic applications as such a hybrid system solves the problem of both quantity and mobility of photocarriers. In this work, a hybrid system comprising of monolayer graphene and self-doped colloidal copper phosphide (Cu3−xP) QDs is developed for efficient broadband photodetection. Unlike conventional PbS QDs that are toxic, Cu3−xP QDs are environmental friendly and have plasmonic resonant absorption in near-infrared (NIR) wavelength. The half-covered graphene with Cu3−xP nanocrystals (NCs) behaves as a self-driven p–n junction and shows durable photoresponse in NIR range. A comparison experiment reveals that the surface ligand attached to Cu3−xP NCs plays a key role in determining the charge transfer efficiency from Cu3−xP to graphene. The most efficient three-terminal photodetectors based on graphene-Cu3−xP exhibit broadband photoresponse from 400 to 1550 nm with an ultrahigh responsivity (1.59 × 105 A W−1) and high photoconductive gain (6.66 × 105) at visible wavelength (405 nm), and a good responsivity of 9.34 A W−1 at 1550 nm. The demonstration of flexible graphene-Cu3−xP photodetectors operated at NIR wavelengths may find potential applications in optical sensing, biological imaging, and wearable devices.

High-performance and broadband photodetectors based on the hybrid graphene-Cu3−xP nanocrystal structure are demonstrated. A flexible graphene-Cu3−xP photodetector on polyethylene naphthalate substrate capable of infrared (IR) light detection is realized and the photocurrent shows no obvious degradation even after 5000 times bending, indicating a very good flexibility. This work paves a new way for fabrication of broadband and flexible IR optoelectronic devices.

Mediatorless, Reversible Optical Nanosensor Enabled through Enzymatic Pocket Doping

By Vitalijs Zubkovs, Nils Schuergers, Benjamin Lambert, Esra Ahunbay, Ardemis A. Boghossian from Small. Published on Sep 22, 2017.

Single-walled carbon nanotubes (SWCNTs) exhibit intrinsic near-infrared fluorescence that benefits from indefinite photostability and tissue transparency, offering a promising basis for in vivo biosensing. Existing SWCNT optical sensors that rely on charge transfer for signal transduction often require exogenous mediators that compromise the stability and biocompatibility of the sensors. This study presents a reversible, mediatorless, near-infrared glucose sensor based on glucose oxidase-wrapped SWCNTs (GOx-SWCNTs). GOx-SWCNTs undergo a selective fluorescence increase in the presence of aldohexoses, with the strongest response toward glucose. When incorporated into a custom-built membrane device, the sensor demonstrates a monotonic increase in initial response rates with increasing glucose concentrations between 3 × 10−3 and 30 × 10−3m and an apparent Michaelis–Menten constant of KM(app) ≈ 13.9 × 10−3m. A combination of fluorescence, absorption, and Raman spectroscopy measurements suggests a fluorescence enhancement mechanism based on localized enzymatic doping of SWCNT defect sites that does not rely on added mediators. Removal of glucose reverses the doping effects, resulting in full recovery of the fluorescence intensity. The cyclic addition and removal of glucose is shown to successively enhance and recover fluorescence, demonstrating reversibility that serves as a prerequisite for continuous glucose monitoring.

Conformal Coating of Co/N-Doped Carbon Layers into Mesoporous Silica for Highly Efficient Catalytic Dehydrogenation–Hydrogenation Tandem Reactions

By Zhujun Zhang, Xiangru Wei, Yan Yao, Zhi Chen, Aijian Zhang, Wei Li, Winston Duo Wu, Zhangxiong Wu, Xiao Dong Chen, Dongyuan Zhao from Small. Published on Sep 22, 2017.

To maximize the utilizing efficiency of cobalt (Co) and optimize its catalytic activity and stability, engineering of size and interfacial chemical properties, as well as controllable support are of ultimate importance. Here, the concept of coating uniform thin Co/N-doped carbon layers into the mesopore surfaces of mesoporous silica is proposed for heterogeneous aqueous catalysis. To approach the target, a one-step solvent-free melting-assisted coating process, i.e., heating a mixture of a cobalt salt, an amino acid (AA), and a mesoporous silica, is developed for the synthesis of mesoporous composites with thin Co/N-doped carbon layers uniformly coated within mesoporous silica, high surface areas (250–630 m2 g−1), ordered mesopores (7.0–8.4 nm), and high water dispersibility. The strong silica/AA adhesive interactions and AA cohesive interactions direct the uniform coating process. The metal/N coordinating, carbon anchoring, and mesopore confining lead to the formation of tiny Co nanoclusters. The carbon intercalation and N coordination optimize the interfacial properties of Co for catalysis. The optimized catalyst exhibits excellent catalytic performance for tandem hydrogenation of nitrobenzene and dehydrogenation of NaBH4 with well-matched reaction kinetics, 100% conversion and selectivity, high turnover frequencies, up to ≈6.06 molnitrobenzene molCo−1 min−1, the highest over transition-metal catalysts, and excellent stability and magnetic separability.

Thu 16 Nov 13:10: Multimodal driver displays, autonomous car handovers, and inclusiveness

From All Talks (aka the CURE list). Published on Sep 21, 2017.

Multimodal driver displays, autonomous car handovers, and inclusiveness

In this talk, I will discuss some of my PhD and my PostDoc work on multimodal driver displays, autonomous car handovers, and inclusiveness. During my PhD, I investigated the utility of multimodal driver displays, meaning multisensory ways to alert drivers about events on the road, using audio, vibration, and visual cues. I studied the effectiveness of such displays in both manual and autonomous driving scenarios, and found that they can help people to recognise the urgency of the situation signified. My fascination for this topic, as well as the fact that autonomous cars are quickly becoming a reality, led me to pursue research in autonomous cars also in my PostDoc. I am currently working at the Department of Engineering, Engineering-Design Centre, as part of the project Human Interaction: Designing Autonomy in Vehicles, funded by EPSRC and Jaguar-Land Rover. The focus of the project is to design inclusive interfaces for autonomous cars, meaning interfaces that most people (and not only highly technical and highly capable people) are likely to find useful. A particularly critical part of the interaction between the car and the driver in autonomous cars, are the transitions between manual and autonomous modes, called handovers of control. Through an iterative design cycle, involving questionnaires, focus groups, and design workshops, we created a set of design concepts to assist these handovers. We then designed a set of dialogue interactions for this transition, and evaluated them with an inclusive user group in an autonomous car simulator. We revealed the potential of using our dialogue-based concepts for handovers, and are now improving them based on our findings, expecting to test them on a test track and on the road in the coming years.

Thu 12 Oct 13:10: Graphene for ultrafast lasers

From All Talks (aka the CURE list). Published on Sep 21, 2017.

Graphene for ultrafast lasers

Laser sources producing nanosecond (10-9 s) to sub-picosecond (10-12 s) pulses (i.e. ultrafast lasers) are deployed in a variety of applications ranging from scientific research, laser surgery, material processing and telecommunications. Regardless of the output wavelength, the majority of ultrafast laser systems employ a mode-locking technique, whereby a nonlinear optical element – called Saturable Absorber (SA) – turns the laser continuous wave output into a train of ultrashort optical pulses. The SA absorption (or optical loss) decreases as the incident light intensity increases. Thus, the SA works as an intensity-dependent optical switch. The key requirements for SAs are fast response time, high modulation depth, broad wavelength range, low optical loss, low-cost and ease of integration into an optical system. Graphene, a one atom thick layer of carbon atoms arranged in a honeycomb lattice, can simultaneously meet all these needs with better performances and lower cost compared to current technologies. In this seminar I will introduce the basic concepts of ultrafast lasers and mode-locking and their importance for technological applications. I will then review the fundamental physical properties that make graphene the ideal candidate as saturable absorber for ultrafast lasers on an extremely broad energy range from visible to THz.

In article number 1702207, Laura De Laporte and co-workers report a novel anisotropic injectable hydrogel that promotes unidirectional nerve growth in a 3D microenvironment. The hybrid hydrogel comprises short magneto-responsive fibers, which are produced via an electrospinning/cryocutting method. After injection, they orient in a low external magnetic field, while the hydrogel crosslinks to fix the direction of the matrix. The grown nerves are functional with spontaneous electrical activity parallel to the direction of the fibers.

Thermoplasmonics: Molecular Hyperthermia: Spatiotemporal Protein Unfolding and Inactivation by Nanosecond Plasmonic Heating (Small 36/2017)

In article number 1700841, Zhenpeng Qin and co-workers develop a novel method to create highly specific therapies by inactivating dysfunctional protein molecules. The approach inactivates protein molecules of interest by using short laser pulses and nanoparticles. This is achieved by nanosecond plasmonic heating of gold nanoparticles which creates an ultrahigh and ultrashort temperature increase, leading to selective inactivation and unfolding of proteins adjacent to the nanoparticle.

In article number 1701630, Kanna Aoki and co-workers achieve patterning of porosified silicon wafer surfaces using anodic oxidation, and conventional photolithography and wet etching. Subsequent oxidation treatment facilitated self-rolling in the porous silicon layers. Various three-dimensional shapes such as bowls, tubes, and boxes were realized. A direct silicon-processing technology that enables thin layers of silicon surfaces to be bent into various three-dimensional curved structures at the micron scale is useful for expanding the capabilities and design possibilities of on-chip Si devices.

From Materials Chemistry Research Interest Group. Published on Sep 21, 2017.

Predicting and designing the self-assembly of colloidal particles: a computer game

The ability of atomic, colloidal, and nanoparticles to self-organize into highly ordered crystalline structures makes the prediction of crystal structures in these systems an important challenge for science. The question itself is deceivingly simple: assuming that the underlying interaction between constituent particles is known, which crystal structures are stable. In this talk, I will describe a Monte Carlo simulation method [1] combined with a triangular tesselation method [2] to describe the surface of arbitrarily shaped particles that can be employed to predict close-packed crystal structures in colloidal hard-particle systems. I will show that particle shape alone can give rise to a wide variety of structures with unusual properties [3-7], e.g., photonic band gap structures or highly diffusive crystals, but combining the choice of particle shape with external fields, like confinement [4], can enlarge the number of possible structures even more.

Fri 13 Oct 14:00: Self-assembly of Si- and SiGe-based dielectric Mie resonators via templated solid-state dewetting

From Materials Chemistry Research Interest Group. Published on Sep 21, 2017.

Self-assembly of Si- and SiGe-based dielectric Mie resonators via templated solid-state dewetting

ielectric Mie resonators have attracted a great deal of attention over the past few years thanks to their remarkable capabilities in manipulating light propagation at the nanoscale1,2,3. However, the practical implementation of technological products is still elusive. Important limits are the absence of a high-performing material and a fabrication method that can be easily integrated into modern micro-electronic devices at affordable costs. Here, we provide theoretical and experimental evidence of solid state dewetting of ultra-thin silicon and silicon-germanium films on insulators as an alternative fabrication method and semiconductor material for dielectric Mie resonator applications4-7. These dielectric resonant particles can be obtained over very large surfaces4 on arbitrary silica substrates5. Remarkably, this self-assembly process is independent on the sample size. Furthermore, the Si(Ge) islands can be precisely organised in uniform arrays and complex oligomers arrangements6 featuring low size dispersion. Their composition profile can be controlled a posteriori via a Ge condensation process to form core-shell Si/SiGe islands7,8 and their diffusion spectrum can be electrically tuned by changing the refractive index of the environment. As an example, we demonstrate SiGe- based Mie resonator arrays functioning as colour pass-band filters across the full visible spectral range9. The filters function both in transmission and diffusion and are fabricated using a methodology compatible with C- MOS technology. We note that the use of SiGe-based alloys in novel electronic devices, such as FET and C- MOS transistors, is nowadays extremely important. Because of this, opening the field of dielectric MRs to SiGe-based semiconductor alloys is an important step forward towards the integration of photonics with electronic devices.

Tue 26 Sep 15:00: A Bayesian Treatment for Uncertainty -- and its application in health care

From All Talks (aka the CURE list). Published on Sep 21, 2017.

A Bayesian Treatment for Uncertainty -- and its application in health care

Machine learning has enabled and improved many real-life applications. However, when humans interact with machines an estimate of model uncertainty is required, especially in applications such as health care. My research focuses on designing probabilistic models and advancing variational inference for this kind of domain.

In this talk, I will mainly focus on two parts of my work. Firstly, I will present probabilistic latent variable models and their applications in health care. I investigate the question of diagnostic prediction from various sources as a multi-view learning problem setting. I design a general framework consisting of a factorized multi-view topic model for image annotation and diagnostic prediction.

Secondly, I present my recent work on accelerating stochastic approximate inference. We employ determinantal point processes for variance reduction and data re-balancing in stochastic gradient methods. Moreover, we propose a unified view of black-box variational inference and importance sampling, and further introduce perturbative variational inference that can have a mass covering effect but at the same time maintain a low variance.

In the end, I conclude the talk with possible future work in terms of both machine learning theory and its application to health care.

Thu 02 Nov 16:00: Aristotle, projectiles and guns

From All Talks (aka the CURE list). Published on Sep 21, 2017.

Aristotle, projectiles and guns

When guns were developed in Europe in the 14th century, the theory of projectile motion was not the one we are familiar with today due to Galileo and Newton but the one taught by Aristotle approximately 1700 years earlier. In addition to Aristotle’s wide-ranging philosophical concerns, his theory arose from the observation in everyday life that if an object is moving something must be moving it. This idea works very well for the horse and cart but is puzzling if you apply it to a thrown stone or spear. Problems with Aristotle’s theory of projectile motion were identified by one or two people between his time and the 14th century, particularly John Philiponus (6th century AD) and John Buridan (14th century AD). An archer or a spearman does not need a theory of projectile motion, just a great deal of practice. But once the gun was invented it became important to know what angle a barrel should be oriented at and how much propellant to use, particularly as gunpowder was expensive. However, for many years afterwards the manufacturing techniques used meant that cannonballs were a loose fit to gun-barrels making cannons both inaccurate and of poor reproducibility shot-to-shot. Also air resistance makes the trajectory both impossible to calculate and qualitatively similar to theories based on Aristotle’s writings. It was not until Galileo and Newton worked on the problem that a better theory of ideal projectile motion was arrived at.

Thu 12 Oct 13:00: Misreporting and Feedback Effect

From All Talks (aka the CURE list). Published on Sep 20, 2017.

Misreporting and Feedback Effect

Stock price often provides firms with new information, which can be used in the firms’ subsequent real decisions. We examine how this informational feedback from the financial market affects a myopic firm manager’s incentive to misreport, and how the misreporting further affects the firm’s price and value. We find that the manager overstates his report more in the presence of feedback, but this misreporting brings forth both positive price and real effects for the firm. Intuitively, overstating the report encourages information production in the market because (a) it renders accounting reports less reliable as a source of information, and (b) investors expect higher trading profits from larger capital investment. The new incremental information improves investment efficiency when it is revealed to the firm manager through trading and used in the firm’s subsequent investment decisions. As a consequence, the capital investment is higher when there is feedback effect.

Lightweight verification of separate compilation

Major compiler verification efforts, such as the CompCert project, have traditionally simplified the verification problem by restricting attention to the correctness of whole-program compilation, leaving open the question of how to verify the correctness of separate compilation. Recently, a number of sophisticated techniques have been proposed for proving more flexible, compositional notions of compiler correctness, but these approaches tend to be quite heavyweight compared to the simple “closed simulations” used in verifying whole-program compilation. Applying such techniques to a compiler like CompCert, as Stewart et.al. have done, involves major changes and extensions to its original verification.

In this talk, I will show that if we aim somewhat lower—to prove correctness of separate compilation, but only for a single compiler—we can drastically simplify the proof effort. Toward this end, we develop several lightweight techniques that recast the compositional verification problem in terms of whole-program compilation, thereby enabling us to largely reuse the closed-simulation proofs from existing compiler verifications. We demonstrate the effectiveness of these techniques by applying them to CompCert 2.4, converting its verification of whole-program compilation into a verification of separate compilation in less than two person-months. This conversion only required a small number of changes to the original proofs, and uncovered two compiler bugs along the way. The result is SepCompCert, the first verification of separate compilation for the full CompCert compiler.

Tuning Excitonic Properties of Monolayer MoS2 with Microsphere Cavity by High-Throughput Chemical Vapor Deposition Method

By Yang Mi, Zhepeng Zhang, Liyun Zhao, Shuai Zhang, Jie Chen, Qingqing Ji, Jianping Shi, Xiebo Zhou, Rui Wang, Jia Shi, Wenna Du, Zhiyong Wu, Xiaohui Qiu, Qing Zhang, Yanfeng Zhang, Xinfeng Liu from Small. Published on Sep 20, 2017.

Tuning the optical properties of 2D direct bandgap semiconductors is crucial for applications in photonic light source, optical communication, and sensing. In this work, the excitonic properties of molybdenum disulphide (MoS2) are successfully tuned by directly depositing it onto silica microsphere resonators using chemical vapor deposition method. Multiple whispering gallery mode (WGM) peaks in the emission wavelength range of ≈650–750 nm are observed under continuous wave excitation at room temperature. Time-resolved photoluminescence (TRPL) and femtosecond transient absorption (TA) spectroscopy are conducted to study light-matter interaction dynamics of the MoS2 microcavities. TRPL study suggests radiative recombination rate of carrier-phonon scattering and interband transition processes in MoS2 is enhanced by a factor of ≈1.65 due to Purcell effect in microcavities. TA spectroscopy study shows modulation of the interband transition process mainly occurs at PB-A band with an estimated F ≈ 1.60. Furthermore, refractive index sensing utilizing WGM peaks of MoS2 is established with sensitivity up to ≈150 nm per refractive index unit. The present work provides a large-scale and straightforward method for coupling atomically thin 2D gain media with cavities for high-performance optoelectronic devices and sensors.

Functionalization of Silicon Nanostructures for Energy-Related Applications

By Naoki Fukata, Thiyagu Subramani, Wipakorn Jevasuwan, Mrinal Dutta, Yoshio Bando from Small. Published on Sep 20, 2017.

Silicon (Si) is used in various application fields such as solar cells and electric devices. Functionalization of Si nanostructures is one way to further improve the properties of these devices such as these. This Review summarizes recent results of solar cell and Li-ion battery applications using Si-related nanostructures. In solar cell applications, the light trapping effect is increased and the carrier recombination rate is decreased due to the short carrier collection path achieved by radially constructed p–n junction in Si nanowires, resulting in higher power conversion efficiency. The nonradiative energy transfer effect created by nanocrystalline Si is a novel way of improving solar cell properties. Si-related nanostructures are also anticipated as new anode materials with higher capacity in Li-ion batteries. Si-related nanocomposite materials which show densely packed microparticle structures agglomerated with small nanoparticles are described here as a promising challenge. These unique structures show higher capacity and longer cycle properties.

Functionalization of silicon nanostructures improve energy-related device performances. Shortened carrier collection paths and enhancement of light-trapping effect by 1-dimensional (1D) nanowire structures and nonradiative energy transfer effect by 0-dimensional (0D) nanocrystal structures effectively increase the power conversion efficiency of solar cells. Silicon-related nanocomposite structures also show higher capacity than commercially available lithium-ion battery anodes and more stable cyclic property than pure Si materials.

Capillarity Composited Recycled Paper/Graphene Scaffold for Lithium–Sulfur Batteries with Enhanced Capacity and Extended Lifespan

By Yunya Zhang, Zan Gao, Xiaodong Li from Small. Published on Sep 20, 2017.

An effective strategy to tackle the twin crises of global deforestation and fossil fuel depletion is to recycle biomass materials for energy storage devices. This study reports a unique and innovative solution to capitalize on a currently overlooked resource to produce high-performance lithium–sulfur (Li–S) batteries from recycled paper. The recycled paper fibers are creatively composited with graphene oxide sheets via a capillary adsorption method. The recycled paper/graphene oxide hybrid is then converted to activated paper carbon/reduced graphene oxide (APC/graphene) scaffold for sulfur infiltration. The assembled Li–APC/graphene/S battery exhibits a superior lifespan of 620 cycles with an excellent capacity retention rate of 60.5%. An APC interlayer is sandwiched between the Li anode and the separator to suppress the degradation of Li anode by preventing the nonhomogeneous growth of mossy Li whiskers, stretching the battery lifespan up to 1000 cycles with a capacitance retention rate of 52.3%. The capillary adsorption method coupled with the porous carbonaceous anode interlayer configuration creates a new opportunity for the development of batteries derived from porous biomass materials.

Large-Area Patterning of Metal Nanostructures by Dip-Pen Nanodisplacement Lithography for Optical Applications

By Lina Chen, Xiaoling Wei, Xuechang Zhou, Zhuang Xie, Kan Li, Qifeng Ruan, Chaojian Chen, Jianfang Wang, Chad A. Mirkin, Zijian Zheng from Small. Published on Sep 20, 2017.

Au nanostructures are remarkably important in a wide variety of fields for decades. The fabrication of Au nanostructures typically requires time-consuming and expensive electron-beam lithography (EBL) that operates in vacuum. To address this challenge, this paper reports the development of massive dip-pen nanodisplacement lithography (DNL) as a desktop fabrication tool, which allows high-throughput and rational design of arbitrary Au nanopatterns in ambient condition. Large-area (1 cm2) and uniform (<10% variation) Au nanostructures as small as 70 nm are readily fabricated, with a throughput 100-fold higher than that of conventional EBL. As a proof-of-concept of the applications in the opitcal field, we fabricate discrete Au nanorod arrays that show significant plasmonic resonance in the visible range, and interconnected Au nanomeshes that are used for transparent conductive electrode of solar cells.

High-throughput massively parallel dip-pen nanolithography is employed for the generation of centimeter scale metallic nanostructures. First, the visible plasmonic resonance for the large-area gold nanorod patterns is demonstrated. Moreover, through patterning, extreme highly transparent conducting electrodes of Au nanomesh with low sheet resistance are fabricated. The device performance is superior to the analogous indium tin oxide based device.

Ultrafast Flame Annealing of TiO2 Paste for Fabricating Dye-Sensitized and Perovskite Solar Cells with Enhanced Efficiency

By Jung Kyu Kim, Sung Uk Chai, Yoonjun Cho, Lili Cai, Sung June Kim, Sangwook Park, Jong Hyeok Park, Xiaolin Zheng from Small. Published on Sep 20, 2017.

Mesoporous TiO2 nanoparticle (NP) films are broadly used as electrodes in photoelectrochemical cells, dye-sensitized solar cells (DSSCs), and perovskite solar cells (PSCs). State-of-the-art mesoporous TiO2 NP films for these solar cells are fabricated by annealing TiO2 paste-coated fluorine-doped tin oxide glass in a box furnace at 500 °C for ≈30 min. Here, the use of a nontraditional reactor, i.e., flame, is reported for the high throughput and ultrafast annealing of TiO2 paste (≈1 min). This flame-annealing method, compared to conventional furnace annealing, exhibits three distinct benefits. First, flame removes polymeric binders in the initial TiO2 paste more completely because of its high temperature (≈1000 °C). Second, flame induces strong interconnections between TiO2 nanoparticles without affecting the underlying transparent conducting oxide substrate. Third, the flame-induced carbothermic reduction on the TiO2 surface facilitates charge injection from the dye/perovskite to TiO2. Consequently, when the flame-annealed mesoporous TiO2 film is used to fabricate DSSCs and PSCs, both exhibit enhanced charge transport and higher power conversion efficiencies than those fabricated using furnace-annealed TiO2 films. Finally, when the ultrafast flame-annealing method is combined with a fast dye-coating method to fabricate DSSC devices, its total fabrication time is reduced from over 3 h to ≈10 min.

Thumbnail image of graphical abstract

Flame is an attractive alternative to the commonly used box furnace to form mesoporous TiO2 films. It demonstrates the advantages of a significantly reduced processing time, better removal of organic impurities, and efficient connectivity. The energy state of the TiO2 is also modified by carbothermic reduction during the flame, facilitating efficient charge injection from the dye/perovskite to TiO2.

Direct measurements of dynamic granular compaction at the mesoscale using synchrotron X-ray radiography

A grand challenge in the field of dynamic compression is to understand how mesoscale (nanosecond-microsecond, micrometre-millimetre) deformation processes govern macroscopic material behaviour and performance. In this seminar I will discuss the development and application of a novel synchrotron X-ray radiography technique, which is able to make in situ measurements of shock-compression at the mesoscale. Focus will be given to direct measurements of granular compaction in several systems relevant to chondritic asteroid formation, including the observation of normally distributed shock velocities, measurements of shock front thickness, and calculations of spatially-resolved mass density fields.

Analysis of Spatio-temporal Representations for Robust Footstep Recognition with Deep Residual Neural Networks

Human footsteps can provide a unique behavioural pattern for robust biometric systems. We propose spatio-temporal footstep representations from floor-only sensor data in advanced computational models for automatic biometric verification. Our models deliver an artificial intelligence capable of effectively differentiating the fine-grained variability of footsteps between legitimate users (clients) and impostor users of the biometric system. The methodology is validated in the largest footstep database, containing nearly 20,000 footstep signals from more than 120 users. The database contains a large cohort of impostors and a small set of clients to verify the reliability of biometric systems. We provide experimental results in 3 critical data-driven security scenarios, according to the amount of footstep data available for model training: at airports security checkpoints (smallest training set), workspace environments (medium training set) and home environments (largest training set). With this methodology, we report state-of-the-art footstep recognition rates.

Attasi ND systems, polynomial system solving and algebraic optimization

This talk will unify the results about the eigenvalue approach to polynomial system solving from the Attasi ND systems standpoint. In fact one needs to use autonomous Attasi ND systems which were not really defined in Attasi’s original paper. But once that is done the so-called Stetter matrices of a polynomial system with finite number of solutions (over the complex numbers) follow directly from Attasi’s realization theory.

I will then discuss the approach followed in the work with Bleylevens and Peeters on determining the solutions of systems of polynomial equations using large eigenvalue solvers, where we use recursive solution of the ND system equations to obtain the result of the action of the shift matrices on the initial state. I will also describe possibilities for computing these recursions on a FPGA chip by using the FIFO (first-in-first-out) facility.

Self-Powered Ultraviolet Photodetectors Driven by Built-In Electric Field

By Longxing Su, Wei Yang, Jian Cai, Hongyu Chen, Xiaosheng Fang from Small. Published on Sep 19, 2017.

Self-powered ultraviolet (UV) photodetectors, which have vast applications in the military and for civilian purposes, have become particularly attractive in recent years due to their advantages of high sensitivity, ultrasmall size, and low power consumption. In particular, self-powered UV photodetectors driven by a built-in electric field cannot only detect UV signals but also be powered by the incident signals instead of external power. In this concept, the key issues and most recent developments on photovoltaic type UV photodetectors driven by p–n homojunction, heterojunction, and Schottky junction are surveyed. This should generate extensive interest in this field and encourage more researchers to engage in and tackle the scientific challenges.

Sodium–ion batteries (NIBs), due to the advantages of low cost and relatively high safety, have attracted widespread attention all over the world, making them a promising candidate for large-scale energy storage systems. However, the inherent lower energy density to lithium–ion batteries is the issue that should be further investigated and optimized. Toward the grid-level energy storage applications, designing and discovering appropriate anode materials for NIBs are of great concern. Although many efforts on the improvements and innovations are achieved, several challenges still limit the current requirements of the large-scale application, including low energy/power densities, moderate cycle performance, and the low initial Coulombic efficiency. Advanced nanostructured strategies for anode materials can significantly improve ion or electron transport kinetic performance enhancing the electrochemical properties of battery systems. Herein, this Review intends to provide a comprehensive summary on the progress of nanostructured anode materials for NIBs, where representative examples and corresponding storage mechanisms are discussed. Meanwhile, the potential directions to obtain high-performance anode materials of NIBs are also proposed, which provide references for the further development of advanced anode materials for NIBs.

Metrology of Multiphoton Microscopes Using Second Harmonic Generation Nanoprobes

By Pierre Mahou, Guy Malkinson, Élodie Chaudan, Thierry Gacoin, Emmanuel Beaurepaire, Willy Supatto from Small. Published on Sep 19, 2017.

In multiphoton microscopy, the ongoing trend toward the use of excitation wavelengths spanning the entire near-infrared range calls for new standards in order to quantify and compare the performances of microscopes. This article describes a new method for characterizing the imaging properties of multiphoton microscopes over a broad range of excitation wavelengths in a straightforward and efficient manner. It demonstrates how second harmonic generation (SHG) nanoprobes can be used to map the spatial resolution, field curvature, and chromatic aberrations across the microscope field of view with a precision below the diffraction limit and with unique advantages over methods based on fluorescence. KTiOPO4 nanocrystals are used as SHG nanoprobes to measure and compare the performances over the 850–1100 nm wavelength range of several microscope objectives designed for multiphoton microscopy. Finally, this approach is extended to the post-acquisition correction of chromatic aberrations in multicolor multiphoton imaging. Overall, the use of SHG nanoprobes appears as a uniquely suited method to standardize the metrology of multiphoton microscopes.

Second harmonic generation nanoprobes exhibit unique advantages to quantify the performances of multiphoton microscopes over a broad range of light excitation wavelengths. Mapping the spatial resolution, field curvature, and chromatic aberrations across the microscope field of view with a precision below the diffraction limit is critical for many applications, including the correction of chromatic aberrations in multicolor imaging.

From All Talks (aka the CURE list). Published on Sep 19, 2017.

Rapid host-pathogen co-evolution following a severe emerging infectious outbreak

In 1994, Mycoplasma gallisepticum, a common bacterial pathogen of poultry, jumped into house finches (Haemorhous mexicanus) and rapidly spread in the entire eastern North American finch population, causing the death of millions. This emerging infectious disease outbreak is one of the best documented natural epizootic to date and therefore offers unique opportunities to test key questions regarding host shifting and host-pathogen co-evolution. Host resistance was found to have spread from standing genetic variation within 12 years of disease exposure only, and was associated with parallel changes in pathogen virulence. Here I discuss the phenotypic changes that took place over the course of the epizootic in both the host and the pathogen, and show that these phenotypic changes gave rise to significant increases in host and pathogen fitness, as expected under an antagonistic co-evolution scenario.

The response of ice sheets to climate variability

Ice loss from the West Antarctic Ice Sheet is a significant contributor to sea-level rise. The ice loss is thought to have been triggered by fluctuations in the delivery of oceanic heat to the base of ice shelves. However, the response of ice sheets to ocean variability remains poorly understood. Applying a novel synchronously coupled ice-ocean model, this study considers the response of an ice sheet to periodic variations in ocean forcing. The results show that the amplitude of oscillations in grounded ice volume grow as a non-linear function of ocean forcing period. This implies that slower oscillations in climatic forcing are disproportionately important to ice sheets. The residence time of ice shelves offers a critical time scale, above (below) which the ice response amplitude is a linear (quadratic) function of ocean forcing period. These results highlight the sensitivity of West Antarctic ice streams to perturbations in heat fluxes occurring at interannual and decadal time scales.

Balanced embedding of degenerating Abelian varieties

In this talk, we show that after a base change, one can complete a certain family of Abelian varieties over a disc such that the whole degeneration can be simultaneously balanced embedded into a projective space by the theta functions. Then we study the relationship between the balanced filling-in and the Gromov-Hausdorff limit of flat Kahler metrics on the nearby fibers.

From All Talks (aka the CURE list). Published on Sep 18, 2017.

Alzheimer’s Disease: The story so far

In the last decades, there has been a rapid demographic shift, where populations in both developing and developed countries live far longer. Although an indication of medical advances and overall improved health, an increase in lifespan comes with great costs too. Individuals over the age of 65 have an increased chance of developing dementias and neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease, and the chances increase every year. Despite numerous clinical trials and funds invested in testing for new cures and treatments, nothing has yet been found. These diseases, which are still incurable, progressive and eventually fatal, currently represent a tremendous burden on our social systems, as well as the patients’ and their families’ lives. The primary reason why no significant development in treating these conditions has occurred is that we do not really understand their molecular origins. In the Centre for Misfolding diseases we have been working to develop a ‘gene signature’ for such conditions, which will provide us with a tool to gain insight and allow us to recapitulate these diseases, which will test our fundamental understanding of their causes, as well as enabling effective drug discovery programs to be carried out.

From All Talks (aka the CURE list). Published on Sep 18, 2017.

WikiFactMine: Scientific Knowledge for Everyone

Peter Murray-Rust, ContentMine [1] and University of Cambridge

Public funding of science and medicine generates 1 trillion dollars of public knowledge per year but most of this is inaccessible to most people. Working with the Wikimedia Foundation we have developed tools for collecting over 6 million of the world’s open scientific articles and extracting the facts from them into WikiFactMine (WFM) [2] . We use Wikidata [3] which, with over 40 million “items” from Wikipedia or world authorities, is based on modern Open Web technology. WFM reads every new Open scientific article (starting with biomedicine) and indexes the terms against WikiFactMine. It thus becomes a “knowledge prosthetic” or “amanuensis” so that everyone can immediately find the accumulated knowledge in Wikimedia resources.

We believe that with WikiFactMine the scientific literature becomes accessible to a wide range of people and machines. Data in articles can be automatically indexed on fulltext and diagrammatic content creating the base for a new generation of scientific search engines. We have created a wide range of “dictionaries” from Wikidata, allowing multidisciplinary search of articles (e.g. chemistry, diseases, drugs…) . WikiFactMine can expand “find all chemicals produced by conifers” to 500 phytochemicals and 2000 conifers and search for all of them. “What viral diseases have been reported in West Africa” might inform public health policies in a new manner.

The talk will cover the technology (which anyone can use; ContentMine already has a 15-year old contributing) and the politics of academic publication where revenue is often generated by artificial scarcity. Can we find a better way? Everyone can participate in WikiFactMine.

I thank Charles Matthews and Tom Arrow who created WikiFactMine.

Thu 16 Nov 14:00: Invariant Kalman filtering

From All Talks (aka the CURE list). Published on Sep 18, 2017.

Invariant Kalman filtering

The Kalman filter, or more precisely the extended Kalman filter (EKF), is a fundamental engineering tool that is pervasively used in control, robotics, and for various estimation tasks in autonomous systems. The recent field of Invariant extended Kalman filtering, aims at using the geometric structure of the state space and the dynamics to improve the EKF , notably in terms of mathematical guarantees. The methodology essentially applies in the field of localization, navigation, and simultaneous localization and mapping (SLAM) where it is proved to resolve the well-known inconsistencies of the conventional EKF . Albeit recent, its remarkable robustness properties have already prompted a true industrial implementation in the aerospace field.

This talk aims to provide an intuitive introduction to the methodology of invariant Kalman filtering, to underline what the important differences with the conventional EKF are, and to give the main reasons why it resolves the EKF consistency issues for SLAM . This should be of interest to students or researchers intrigued by the application of mathematical theories to practical applications, or interested in finding simple to implement and robust filters for localization, navigation, and SLAM , notably for autonomous vehicle guidance.

Super-Resolution Microscopy Unveils Dynamic Heterogeneities in Nanoparticle Protein Corona

By Natalia Feiner-Gracia, Michaela Beck, Sílvia Pujals, Sébastien Tosi, Tamoghna Mandal, Christian Buske, Mika Linden, Lorenzo Albertazzi from Small. Published on Sep 18, 2017.

The adsorption of serum proteins, leading to the formation of a biomolecular corona, is a key determinant of the biological identity of nanoparticles in vivo. Therefore, gaining knowledge on the formation, composition, and temporal evolution of the corona is of utmost importance for the development of nanoparticle-based therapies. Here, it is shown that the use of super-resolution optical microscopy enables the imaging of the protein corona on mesoporous silica nanoparticles with single protein sensitivity. Particle-by-particle quantification reveals a significant heterogeneity in protein absorption under native conditions. Moreover, the diversity of the corona evolves over time depending on the surface chemistry and degradability of the particles. This paper investigates the consequences of protein adsorption for specific cell targeting by antibody-functionalized nanoparticles providing a detailed understanding of corona-activity relations. The methodology is widely applicable to a variety of nanostructures and complements the existing ensemble approaches for protein corona study.

Super-resolution microscopy allows the visualization and quantification of serum proteins adsorbed into nanoparticles with different surface charges, i.e., the protein corona.

In the past few years, the study of therapeutic RNA nanotechnology has expanded tremendously to encompass a large group of interdisciplinary sciences. It is now evident that rationally designed programmable RNA nanostructures offer unique advantages in addressing contemporary therapeutic challenges such as distinguishing target cell types and ameliorating disease. However, to maximize the therapeutic benefit of these nanostructures, it is essential to understand the immunostimulatory aptitude of such tools and identify potential complications. This paper presents a set of 16 nanoparticle platforms that are highly configurable. These novel nucleic acid based polygonal platforms are programmed for controllable self-assembly from RNA and/or DNA strands via canonical Watson–Crick interactions. It is demonstrated that the immunostimulatory properties of these particular designs can be tuned to elicit the desired immune response or lack thereof. To advance the current understanding of the nanoparticle properties that contribute to the observed immunomodulatory activity and establish corresponding designing principles, quantitative structure–activity relationship modeling is conducted. The results demonstrate that molecular weight, together with melting temperature and half-life, strongly predicts the observed immunomodulatory activity. This framework provides the fundamental guidelines necessary for the development of a new library of nanoparticles with predictable immunomodulatory activity.

Nucleic acid nanoparticles are garnering wide attention for their advantages over traditional macromolecule and protein-based pharmaceuticals; however, challenges remain in combating nanoparticles' unwanted immune responses. Here, the first predictive quantitative structure–activity relationship models are presented for discerning a given nucleic acid nanoparticle's immunomodulatory activity based on its measured physicochemical properties, size, and composition, which are experimentally shown to alter their immunogenicity.

Flexible Photodetectors Based on Novel Functional Materials

By Chao Xie, Feng Yan from Small. Published on Sep 18, 2017.

Flexible photodetectors have attracted a great deal of research interest in recent years due to their great possibilities for application in a variety of emerging areas such as flexible, stretchable, implantable, portable, wearable and printed electronics and optoelectronics. Novel functional materials, including materials with zero-dimensional (0D) and one-dimensional (1D) inorganic nanostructures, two-dimensional (2D) layered materials, organic semiconductors and perovskite materials, exhibit appealing electrical and optoelectrical properties, as well as outstanding mechanical flexibility, and have been widely studied as building blocks in cost-effective flexible photodetection. Here, we comprehensively review the outstanding performance of flexible photodetectors made from these novel functional materials reported in recent years. The photoresponse characteristics and flexibility of the devices will be discussed systematically. Summaries and challenges are provided to guide future directions of this vital research field.

Mesoporous Nanosheet Networked Hybrids of Cobalt Oxide and Cobalt Phosphate for Efficient Electrochemical and Photoelectrochemical Oxygen Evolution

By Bin Liu, Hui-Qing Peng, Cheuk-Nam Ho, Hongtao Xue, Shuilin Wu, Tsz-Wai Ng, Chun-Sing Lee, Wenjun Zhang from Small. Published on Sep 18, 2017.

A novel mesoporous nanosheet networked hybrid comprising Co3O4 and Co3(PO4)2 is successfully synthesized using a facile and scalable method through calcinating the carbon, cobalt hydroxy carbonate, and cobalt phosphate composite precursor. Electron transfer from Co3O4 to Co3(PO4)2, together with the special networked structure and the porous nature of the nanosheets enable the Co3(PO4)2-Co3O4 hybrid to have a high oxygen evolution reaction (OER) activity and outstanding stability in alkaline electrolyte, e.g., an overpotential of 270 mV at current density of 10 mA cm−2, and a Tafel slope of 39 mV dec−1, which are superior to most non-noble metal-based OER electrocatalysts reported thus far and as well the commercial RuO2 electrocatalyst. Furthermore, Co3(PO4)2-Co3O4 hybrid is demonstrated to be used as an efficient cocatalyst to enhance the photoelectrochemical OER performance of BiVO4 photoanode. A significantly increased photocurrent density of 3.0 mA cm−2 at 1.23 V (vs reversible hydrogen electrode, RHE), and a potential reduction of 530 mV with respect to that of bare BiVO4 at the photocurrent density of 0.5 mA cm−2 are achieved. The electron transfer-induced enhancement of OER by a hybrid structure may pave the new routes for the design and synthesis of low-cost catalysts for electrochemical and photoelectrochemical oxygen evolution.

By Jun Yang, Yufei Zhang, Yizhou Zhang, Jinjun Shao, Hongbo Geng, Yu Zhang, Yun Zheng, Mani Ulaganathan, Zhengfei Dai, Bing Li, Yun Zong, Xiaochen Dong, Qingyu Yan, Wei Huang from Small. Published on Sep 18, 2017.

2D Sulfur-doped TiSe2/Fe3O4 (named as S-TiSe2/Fe3O4) heterostructures are synthesized successfully based on a facile oil phase process. The Fe3O4 nanoparticles, with an average size of 8 nm, grow uniformly on the surface of S-doped TiSe2 (named as S-TiSe2) nanoplates (300 nm in diameter and 15 nm in thickness). These heterostructures combine the advantages of both S-TiSe2 with good electrical conductivity and Fe3O4 with high theoretical Li storage capacity. As demonstrated potential applications for energy storage, the S-TiSe2/Fe3O4 heterostructures possess high reversible capacities (707.4 mAh g−1 at 0.1 A g−1 during the 100th cycle), excellent cycling stability (432.3 mAh g−1 after 200 cycles at 5 A g−1), and good rate capability (e.g., 301.7 mAh g−1 at 20 A g−1) in lithium-ion batteries. As for sodium-ion batteries, the S-TiSe2/Fe3O4 heterostructures also maintain reversible capacities of 402.3 mAh g−1 at 0.1 A g−1 after 100 cycles, and a high rate capacity of 203.3 mAh g−1 at 4 A g−1.

Precision in EFT studies for top quark and Higgs physics

In this talk I review recent progress in the computation of processes involving top quarks in the framework of Standard Model Effective Theory including NLO QCD corrections. In particular I will discuss the impact of QCD corrections on top pair production, single top production, and top pair production in association with a photon, a Z boson and a Higgs in the presence of higher-dimensional operators. Results for Higgs production in processes involving top loops will also be discussed. The complementarity of these two classes of processes in constraining top quark operators will be demonstrated.

Thermodynamic balance at ice-ocean interface in theory, models and maybe real life

Thermodynamic ice ablation includes both melting and dissolving of the ice. Existing parametrisations are usually based on the 3-equation model, with equations that describe heat and salt flux balances together with the freezing point equation for sea water. However, these equations do not represent both melting and dissolving conditions, or the transition between these conditions. Nor do the 3 -equations provide a good representation of the two dominant velocity regimes: shear-driven and buoyancy-driven mixing. Turbulent heat and salt transfer coefficients need to reflect different boundary layer structures that may form in varying velocity and temperature regimes.

Here the different conditions and velocity regimes are considered in the in context of multi-year observations of temperature, velocity and ablation rate from under the Ross Ice Shelf. These observations of a dissolving ice shelf in sub-zero conditions can be used to constrain transitions from buoyancy-driven mixing to sheer-driven mixing.

From All Talks (aka the CURE list). Published on Sep 17, 2017.

Approximating conditional distributions

There is a wealth of methods to bound the distance between probability laws. However, when we want to compare two laws conditioned on the outcome of some random experiment, several difficulties arise. On the one hand, conditioning introduces strong dependence between the different components of a model, and most of the methods work well in a regime of weak dependence. However, quite surprisingly, there are also many situations when very different laws have similar, or even identical conditional distributions. In this talk, we discuss the basic ideas of a general procedure to adapt Stein’s method to bound the distance between conditional distributions and present two fundamental applications, where conditional laws arise naturally: the case of random walk bridges and the filtering equation. Joint work with A. Chiarini (ETH Zurich) and G. Conforti (École Polytechnique).​

Mon 23 Oct 18:00: On dangerous ground: understanding earthquake induced soil liquefaction

From All Talks (aka the CURE list). Published on Sep 16, 2017.

On dangerous ground: understanding earthquake induced soil liquefaction

Earthquakes cause tremendous damage to man-made structures. Soil liquefaction and the associated phenomena are the main cause for extensive damage to infrastructure. Solid ground that normally offers good support to the structures can turn into a semi-liquid state temporarily under the action of earthquake loading. This results in structures sinking into the ground and/or rotating severely. Underground structures such as tunnels and pipelines can float towards ground surface.

In this lecture examples of damage to structures from soil liquefaction observed in the recent earthquakes such as the New Zealand earthquakes of 2011, Haiti earthquake of 2010 and other such events will be presented. The basic mechanisms at play while the granular matter turns into a semi-liquid state will be discussed. Modelling of liquefaction problems is very interesting. Mathematically it involves solving of coupled differential equations if one follows the finite element method. Physically, liquefaction modelling requires the use of a high gravity centrifuge in conjunction with powerful earthquake actuators that fly on the centrifuge. The development of earthquake actuators at Cambridge from simple mechanical Stored Angular Momentum (SAM) actuator to the sophisticated Servo-hydraulic actuators will be highlighted. Some example problems will be considered which were modelled using both mathematical and physical modelling tools. Some of the boundary value problems will highlight how physical modelling can clarify mechanisms of failure for the cases shallow and deep foundations.

The lecture will end by raising some philosophical questions relating to earthquake induced soil liquefaction. Do individual grains lose contact during liquefaction? Will this lead to opening of gaps/cracks in an intact body of soil? What happens to the soil in that state if it is subjected to shearing? Can the soil below buildings really turn into ‘dangerous ground’?

LARMOR LECTURE - Exoplanets, on the hunt of Universal life

The present exoplanets collection is not only made of gas giants like our own Jupiter, but also includes a steeply fraction of smaller planets some believed to be of similar composition than the Earth. For some of these exoplanets basic information on their atmospheric properties have even been retrieved. These early results are paving the way for future atmospheric studies of habitable terrestrial exoplanets with the hope to obtain a solid evidence of the existence of life around another star. Confined for centuries to the category of pure speculation and philosophical debates, the existence of life outside our solar system, is at the edge of reaching the stage of a testable scientific hypothesis.

Three phases of genome sequencing and their consequences for science and medicine

Over the last 20 years genome sequencing has had a profound impact on the biological sciences and related applications in medicine and agriculture. There have been three phases, each associated with a change in technology. The first, in which Fred Sanger’s sequencing chemistry was automated in the first sequencing machines, led to the reference genome sequences of human and a few other key species. This enabled genomic biology. In the second phase, highly parallel “next generation” short read sequencing technologies allowed sequencing thousands of humans and individuals from other species for which a reference was already available, giving us the ability to study genetic variation directly. This has led to rapidly increasing applications of DNA sequencing in clinical medicine, and has connected two scientific areas, population genetics and molecular biology. In the last few years, new single molecule sequencing technologies have become viable at scale, giving sequencing reads hundreds of times longer than the previous methods, which allow us to efficiently determine from scratch the genome sequences of arbitrary species. Extrapolating long term trends of cost reduction and throughput increases, we can see we are entering a third phase of genome sequencing in which we will sequence all million or so known species, with potential major consequences for the study of diversity and evolution, and for conservation.

Recent Developments in Centrifuge Modelling at the Federal University of Rio de Janeiro

In the last 20 years, the COPPE -UFRJ centrifuge modelling group has pioneered multiple gravity physical modelling in Brazil, comprising drum and beam centrifuges. Recently, simulations covering the lateral, vertical and axial response of risers at the touch down point were undertaken under the auspices of Technip/FMC. In addition to this subject, studies on the behaviour of pipelines buried in compressive soils and in soils subject to mass movements were conducted in collaboration with PETROBRAS .

In 2015, a new research topic on the instability of submarine clay slopes under seismic loading was initiated in cooperation with IFFSTAR and PETROBRAS to understand the effect of topography on seismic response. Additional study covers the physical modelling of a debris flow in a submarine environment using a drum centrifuge for run-out simulations. In parallel, rheological studies were undertaken to help understand the importance of these parameters in the overall phenomena.

You are what you eat? Gut bacteria and mating preferences in Drosophila

We are increasingly coming to understand that the gut microbiota has diverse and important effects on myriad host processes beyond digestion. One area that has remained relatively understudied until recently, is the role gut bacteria has in mediating host behaviour. This is despite research in the 70s that suggested there could be links between commensal bacterial, host odour, and kin recognition. In this talk Zen will showcase recent studies in varied species of Drosophila, that suggest a link between gut bacteria and mating behaviour, mediated by the action of the gut on pheromones.

Tuning of CO2 Reduction Selectivity on Metal Electrocatalysts

By Yuhang Wang, Junlang Liu, Yifei Wang, Abdullah M. Al-Enizi, Gengfeng Zheng from Small. Published on Sep 14, 2017.

Climate change, caused by heavy CO2 emissions, is driving new demands to alleviate the rising concentration of atmospheric CO2 levels. Enlightened by the photosynthesis of green plants, photo(electro)chemical catalysis of CO2 reduction, also known as artificial photosynthesis, is emerged as a promising candidate to address these demands and is widely investigated during the past decade. Among various artificial photosynthetic systems, solar-driven electrochemical CO2 reduction is widely recognized to possess high efficiencies and potentials for practical application. The efficient and selective electroreduction of CO2 is the key to the overall solar-to-chemical efficiency of artificial photosynthesis. Recent studies show that various metallic materials possess the capability to play as electrocatalysts for CO2 reduction. In order to achieve high selectivity for CO2 reduction products, various efforts are made including studies on electrolytes, crystal facets, oxide-derived catalysts, electronic and geometric structures, nanostructures, and mesoscale phenomena. In this Review, these methods for tuning the selectivity of CO2 electrochemical reduction of metallic catalysts are summarized. The challenges and perspectives in this field are also discussed.

Kinetic-Controlled Formation of Bimetallic Metal–Organic Framework Hybrid Structures

By Wenhan Guo, Wei Xia, Kunting Cai, Yingxiao Wu, Bin Qiu, Zibin Liang, Chong Qu, Ruqiang Zou from Small. Published on Sep 14, 2017.

Heterometallic metal–organic frameworks (MOFs) are constructed from two or more kinds of metal ions, while still remaining their original topologies. Due to distinct reaction kinetics during MOF formation, partial distribution of different metals within a single MOF crystal can lead to sophisticated heterogeneous nanostructures. Here, this study reports an investigation of reaction kinetics for different metal ions in a bimetallic MOF system, the ZIF-8/67 (M(2-mIM)2, M = Zn for ZIF-8, and Co for ZIF-67, 2-mIM = 2-methylimidazole), by in situ optical method. Distinct kinetics of the two metals forming single-component MOFs are revealed, and when both Co and Zn ions are present in the starting solution, homogeneous distributions of the two metals are only achieved at high Co/Zn ratio, while at low Co/Zn ratio concentration gradient from Co-rich cores to Zn-rich shells is observed. Further, by adding the two metals in sequence, more sophisticated structures are achieved. Specifically, when Co2+ is added first, ZIF-67@ZIF-8/67 core–shell nanocrystals are achieved with tunable core/shell thickness ratio depending on the time intervals; while when Zn2+ is added first, only agglomerates of irregular shape form due to the weak nucleation ability of Zn2+.

Genetic and Epigenetic Control of Parental Care

Behaviour, like any other phenotype, is traceable to how and when genes are expressed with distinct transcriptional profiles associated with distinct behaviours, even short-term behaviours. My laboratory interrogates the molecular mechanisms that initiate and stabilize social behaviours. We use the burying beetle Nicrophorus vespilloides as a study species. We use this species’ elaborate parental care to dissect the association of behaviour and social context with gene expression. Currently, we are most interested in epigenetic mechanisms and how they regulate gene expression during behavioural changes.

From All Talks (aka the CURE list). Published on Sep 14, 2017.

Growing old yet staying young: do bats hold the secret of extended longevity?

Of all mammals, bat possess the most unique and peculiar adaptations that render them as excellent models to investigate the mechanisms of extended longevity and potentially halted senescence. Indeed, they are the longest-lived mammals relative to their body size, with the oldest bat caught being 41 years old, living approx. 9.8 times longer than expected. Bats defy the ‘rate-of-living’ theories that propose a positive correlation between body size and longevity as they use twice the energy as other species of considerable size, but live far longer. The mechanisms that bats use to avoid the negative physiological effects of their heightened metabolism and deal with an increased production of deleterious Reactive Oxygen Species (ROS) is not known, however it is suggested that they either prevent or repair ROS damage. Bats also appear to have resistance to many viral diseases such as rabies, SARS and Ebola and have been shown to be reservoir species for a huge diversity of newly discovered viruses. This suggests that their innate immunity is different to other mammals, perhaps playing a role in their unexpected longevity. Here the potential genomic basis for their rare immunity and exceptional longevity is explored across multiple bat genomes and divergent ‘ageing’ related markers. A novel blood based population-level transcriptomics approach is developed to explore the molecular changes that occur in an ageing wild population of bats to uncover how bats ‘age’ so slowly compared with other mammals. This can provide a deeper understanding of the causal mechanisms of ageing, potentially uncovering the key molecular pathways that can be eventually modified to halt, alleviate and perhaps even reverse this process in man.

A DNA Origami Mechanical Device for the Regulation of Microcosmic Structural Rigidity

By Neng Wan, Zhouping Hong, Huading Wang, Xin Fu, Ziyue Zhang, Chao Li, Han Xia, Yan Fang, Maoteng Li, Yi Zhan, Xiangliang Yang from Small. Published on Sep 13, 2017.

DNA origami makes it feasible to fabricate a tremendous number of DNA nanostructures with various geometries, dimensions, and functionalities. Moreover, an increasing amount of research on DNA nanostructures is focused on biological and biomedical applications. Here, the reversible regulation of microcosmic structural rigidity is accomplished using a DNA origami device in vitro. The designed DNA origami monomer is composed of an internal central axis and an external sliding tube. Due to the external tube sliding, the device transforms between flexible and rigid states. By transporting the device into the liposome, the conformational change of the origami device induces a structural change in the liposome. The results obtained demonstrate that the programmed DNA origami device can be applied to regulate the microcosmic structural rigidity of liposomes. Because microcosmic structural rigidity is important to cell proliferation and function, the results obtained potentially provide a foundation for the regulation of cell microcosmic structural rigidity using DNA nanostructures.

A DNA origami monomer is constructed with a central axis and an external sliding tube, of which the linear motion is regulated by fuel and antifuel strands. Significantly, when flexible dimer reacts with fuel strand, it undergoes conformational change into rigid one, increasing the structural rigidity of liposomes. This work provides an idea to regulate cell's rigidity in future research.

Optical and Optoelectronic Property Analysis of Nanomaterials inside Transmission Electron Microscope

By Joseph F. S. Fernando, Chao Zhang, Konstantin L. Firestein, Dmitri Golberg from Small. Published on Sep 13, 2017.

In situ transmission electron microscopy (TEM) allows one to investigate nanostructures at high spatial resolution in response to external stimuli, such as heat, electrical current, mechanical force and light. This review exclusively focuses on the optical, optoelectronic and photocatalytic studies inside TEM. With the development of TEMs and specialized TEM holders that include in situ illumination and light collection optics, it is possible to perform optical spectroscopies and diverse optoelectronic experiments inside TEM with simultaneous high resolution imaging of nanostructures. Optical TEM holders combining the capability of a scanning tunneling microscopy probe have enabled nanomaterial bending/stretching and electrical measurements in tandem with illumination. Hence, deep insights into the optoelectronic property versus true structure and its dynamics could be established at the nanometer-range precision thus evaluating the suitability of a nanostructure for advanced light driven technologies. This report highlights systems for in situ illumination of TEM samples and recent research work based on the relevant methods, including nanomaterial cathodoluminescence, photoluminescence, photocatalysis, photodeposition, photoconductivity and piezophototronics.

Myoglobin and Polydopamine-Engineered Raman Nanoprobes for Detecting, Imaging, and Monitoring Reactive Oxygen Species in Biological Samples and Living Cells

By Sumit Kumar, Amit Kumar, Gyeong-Hwan Kim, Won-Kyu Rhim, Kevin L. Hartman, Jwa-Min Nam from Small. Published on Sep 13, 2017.

Highly reliable detection, imaging, and monitoring of reactive oxygen species (ROS) are critical for understanding and studying the biological roles and pathogenesis of ROS. This study describes the design and synthesis of myoglobin and polydopamine-engineered surface-enhanced Raman scattering (MP-SERS) nanoprobes with strong, tunable SERS signals that allow for specifically detecting and imaging ROS sensitively and quantitatively. The study shows that a polydopamine nanolayer can facilitate the modification of Raman-active myoglobins and satellite Au nanoparticles (s-AuNPs) to a plasmonic core AuNP (c-AuNP) in a controllable manner and the generation of plasmonically coupled hot spots between a c-AuNP and s-AuNPs that can induce strong SERS signals. The six-coordinated Fe(III)-OH2 of myoglobins in plasmonic hotspots is reacted with ROS (H2O2, •OH, and O2) to form Fe(IV)[DOUBLE BOND]O. The characteristic Raman peaks of Fe(IV)[DOUBLE BOND]O from the Fe-porphyrin is used to analyze and quantify ROS. This chemistry allows for these probes to detect ROS in solution and image ROS in cells in a highly designable, specific, and sensitive manner. This work shows that these MP-SERS probes allow for detecting and imaging ROS to differentiate cancerous cells from noncancerous cells. Importantly, for the first time, SERS-based monitoring of the autophagy process in living cells under starvation conditions is validated.

Core–Shell Nanoparticle Clusters Enable Synergistic Integration of Plasmonic and Catalytic Functions in a Single Platform

By Seunghoon Lee, Younghyun Wy, Young Wook Lee, Kyungrok Ham, Sang Woo Han from Small. Published on Sep 13, 2017.

Designing controlled hybrid nanoarchitectures between plasmonic and catalytic materials is of paramount importance to fully exploit each function of constituent materials. This study reports a new synthetic strategy for the realization of colloidal clusters of core–shell nanoparticles with plasmonic cores and catalytically active shells. The Au@M (M = Pd or Pt) nanoparticle clusters (NPCs) with a high density of sub-1 nm interparticle gaps are successfully prepared by the deposition of M shells onto thermally activated Au NPCs. NPCs with other metal, metal sulfide, and metal oxide shells can also be synthesized by using the present approach. The prepared Au@M NPCs show remarkably enhanced plasmonic performance compared to their Au@M nanoparticle counterparts due to the localization of a strong electromagnetic field at the interparticle gaps, while the inherent catalytic function of shells is intact. In situ real-time Raman spectroscopy and plasmon-enhanced electrocatalysis experiments demonstrate that the controlled assembly of core–shell nanoparticles is a very effective route for the synergistic integration of plasmonic and catalytic functions in a single platform.

Layer Structured Materials for Advanced Energy Storage and Conversion

By Yanpeng Guo, Yaqing Wei, Huiqiao Li, Tianyou Zhai from Small. Published on Sep 13, 2017.

Owing to the strong in-plane chemical bonds and weak van der Waals force between adjacent layers, investigations of layer structured materials have long been the hotspots in energy-related fields. The intrinsic large interlayer space endows them capabilities of guest ion intercalation, fast ion diffusion, and swift charge transfer along the channels. Meanwhile, the well-maintained in-plane integrity contributes to exceptional mechanical properties. This anisotropic structural feature is also conducive to effective chemical combination, exfoliation, or self-assembly into various nanoarchitectures, accompanied by the introduction of defects, lattice strains, and phase transformation. This review starts with a brief introduction of typical layered materials and their crystal structures, then the structural characteristics and structure oriented unique applications in batteries, capacitors, catalysis, flexible devices, etc., are highlighted. It is surprising to observe that layered materials possess: (1) high reactivity, high reversibility, and enhanced performance via forming additional chemical bonds in alkali-metal ion batteries; (2) facile phase modulation, great feasibility for in-plane/sandwich device design, and cation intercalation enabled high capacitance in supercapacitors; (3) promoted structural diversity, effective strain engineering, and capabilities to function as ideal supporting materials/templates in electrocatalysis field. Finally, the future prospects and challenges faced by layered materials are also outlined.

The strong in-plane chemical bonds and weak van der Waals force between adjacent layers endow layer structured materials with large interlayer space and capabilities of space modulation, high in-plane conductivity, considerable active sites, abilities of effective exfoliation and defect/phase/strain engineering. Moreover, they exhibit superior mechanical properties, leading to unique performances in batteries, supercapacitors, catalysis, flexible devices, etc.

Poly(vinylpyrrolidone)-Free Multistep Synthesis of Silver Nanoplates with Plasmon Resonance in the Near Infrared Range

By Assad U. Khan, Zhengping Zhou, Joseph Krause, Guoliang Liu from Small. Published on Sep 13, 2017.

Herein, a poly(vinylpyrrolidone) (PVP)-free method is described for synthesizing Ag nanoplates that have localized surface plasmon resonance in the near-infrared (NIR) range. Citrate-capped Ag spherical nanoparticles are first grown into small Ag nanoplates that resonate in the range of 500–800 nm. The small Ag nanoplates are used as seeds to further grow into large Ag nanoplates with a lateral dimension of 100–600 nm and a plasmon resonance wavelength of 800–1660 nm and above. The number of growth steps can be increased as desired. Without introducing additional citrate into the solutions of small Ag nanoplate seeds, large Ag nanoplates can be synthesized within minutes. The entire synthesis is completely PVP free, which promotes the nanoparticle growth along the lateral direction to form large Ag nanoplates. The multistep growth and the minimum usage of citrate are essential for the fast growth of high-aspect-ratio Ag nanoplates resonating in the NIR range.

Poly(vinylpyrrolidone) (PVP)-free multistep growth is used to synthesize high-aspect-ratio Ag nanoplates with plasmon resonance in the near-infrared region. Citrate-capped Ag spherical seeds, instead of the PVP-capped ones, are used to expedite the synthesis and avoid any polymer coating around the Ag nanoplates.

Synthesis of Gold Nanoparticle-Embedded Silver Cubic Mesh Nanostructures Using AgCl Nanocubes for Plasmonic Photocatalysis

By Jang Ho Joo, Byung-Ho Kim, Jae-Seung Lee from Small. Published on Sep 13, 2017.

A novel room-temperature aqueous synthesis for gold nanoparticle-embedded silver cubic mesh nanostructures using AgCl templates via a template-assisted coreduction method is developed. The cubic AgCl templates are coreduced in the presence of AuCl4 and Ag+, resulting in the reduction of AuCl4 into gold nanoparticles on the outer region of AgCl templates, followed by the reduction of AgCl and Ag+ into silver cubic mesh nanostructures. Removal of the template clearly demonstrates the delicately designed silver mesh nanostructures embedded with gold nanoparticles. The synthetic mechanism, structural properties, and surface functionalization are spectroscopically investigated. The plasmonic photocatalysis of the cubic mesh nanostructures for the degradation of organic pollutants and removal of highly toxic metal ions is investigated; the photocatalytic activity of the cubic mesh nanostructures is superior to those of conventional TiO2 catalysts and they are catalytically functional even in natural water, owing to their high surface area and excellent chemical stability. The synthetic development presented in this study can be exploited for the highly elaborate, yet, facile design of nanomaterials with outstanding properties.

By Xudong Wang, Chunhua Yao, Fei Wang, Zhaodong Li from Small. Published on Sep 13, 2017.

Cellulose is the most abundant natural polymer on earth, providing a sustainable green resource that is renewable, degradable, biocompatible, and cost effective. Recently, nanocellulose-based mesoporous structures, flexible thin films, fibers, and networks are increasingly developed and used in photovoltaic devices, energy storage systems, mechanical energy harvesters, and catalysts components, showing tremendous materials science value and application potential in many energy-related fields. In this Review, the most recent advancements of processing, integration, and application of cellulose nanomaterials in the areas of solar energy harvesting, energy storage, and mechanical energy harvesting are reviewed. For solar energy harvesting, promising applications of cellulose-based nanostructures for both solar cells and photoelectrochemical electrodes development are reviewed, and their morphology-related merits are discussed. For energy storage, the discussion is primarily focused on the applications of cellulose-based nanomaterials in lithium-ion batteries, including electrodes (e.g., active materials, binders, and structural support), electrolytes, and separators. Applications of cellulose nanomaterials in supercapacitors are also reviewed briefly. For mechanical energy harvesting, the most recent technology evolution in cellulose-based triboelectric nanogenerators is reviewed, from fundamental property tuning to practical implementations. At last, the future research potential and opportunities of cellulose nanomaterials as a new energy material are discussed.

Finite-State Transducers as a Theory of Dependency Structured Natural Language

Important families of dependency graphs are STRONGLY equivalent to context-free languages whose strings encode the graphs. The consequences of this observation (in ACL 2017 ) increase (i) the scope of the classical context-free grammars by allowing them to generate non-trees, (ii) the relevance of strictly locally testable languages to nonlocal graphical properties, and (iii) the applicability of superbracketing schemes beyond the bracketing of single-headed phrase-structures. The second part of the talk is about the work in progress and considers minimal recursion in the encoded graphs. My preliminary experimental results (in FSMNLP 2017 ) on the Universal Dependencies v2 treebanks indicate that a quite small subset approximation of an encoded family of dependency graphs would already capture 99.994% of the primary dependency structures if the encoding scheme is IMPLICITLY extended to crossing brackets. This raises interesting questions about the expressiveness of the finite-state grammar over graph banks and its potential applications to linear time encoding and decoding tasks in dependency parsing and machine translation.

Bonfires with a Bang. Spectacular Chemistry Demonstration Lecture

We are delighted to welcome back the inimitable Dr Andy Szydlo for this year’s Bonfire Night spectacular Chemistry lecture (his previous Cambridge lectures have been truly memorable!).

Dr Szydlo will educate, entertain and enlighten all ages on the subject of bonfires and bangs.

Starting with the Chemistry of bonfires: the gaseous, liquid and solid products which are formed as intermediates during the combustion of wood; dry distillation (pyrolysis) and gas, wood tar, charcoal; gaseous and solid (ash) products of the final products of combustion (oxidation) of wood will be shown and discussed.Then a brief history of the science of bangs will introduce the chemistry and physics of thunder and lightning.

Throughout the talk, anecdotal material from the history of science will be used to enhance the explanations. A total of 21 experiments, with widely varying effects, will be shown.

An enthusiastic and engaging science communicator, Dr Szydlo frequently gives lectures in the UK and has appeared on Channel 4’s TV series That’ll teach ‘em. He is also an expert on the history of alchemy. His book, Water that does not wet hands: The Alchemy of Michael Sendivogius, tells the story of an unfairly forgotten Polish alchemist.

WARNING – There will be smoke, bright flashes and loud bangs!

The lecture is for all ages (>8), but not suitable for those with a nervous disposition.

Free admission. No tickets – so come early to get a good seat. Doors open at 18:30. Please contact organisers if you are bringing a large party (>10). Organised by SCI Cambridge & Great Eastern Region, RSC Mid-Anglia Section.

From All Talks (aka the CURE list). Published on Sep 13, 2017.

Could pluripotent stem cells ever be used for equine tendon regeneration?

Equine pluripotent stem cells have been derived from the inner cell mass of blastocyst stage embryos (embryonic stem cells, ESCs) and from the reprogramming of adult cells into a pluripotent state (induced pluripotent stem cells, iPSCs).

ESCs differentiate into tenocytes in vivo following their injection into an injured horse tendon and in vitro in response to transforming growth factor beta 3 (TGFβ3) and/or 3D culture in an anchored collagen matrix.

Here we demonstrate that while equine iPSCs express tendon-associated genes and proteins following TGF -β3 exposure in 2D culture, they cannot remodel a 3D collagen matrix to generate “artificial tendons”. This demonstrates the utility of the 3D in vitro tendon assay for measuring functional tendon differentiation and the need for more detailed studies to be performed to determine if epigenetic differences exist between equine iPSCs and ESCs.

To ensure the safety of pluripotent stem cells in the clinic the mechanisms controlling their differentiation must be understood. We have demonstrated that the transcription factor scleraxis is required for tendon differentiation by equine ESCs, as the overexpression of a short hairpin RNA (shRNA) to scleraxis leads to a failure to generate artificial tendons in 3D culture. Scleraxis is also required for the generation of artificial tendons by fetal tenocytes and its knockdown using shRNA results in a significant reduction in the expression of COL1A1 , COMP and SOX9 . These effects can subsequently be rescued through scleraxis overexpression. In contrast, adult tenocytes expressing a shRNA to scleraxis demonstrated no changes in the expression levels of the genes measured and the cells continued to generate artificial tendons as normal in 3D culture.

A further safety consideration is in understanding the immune properties of pluripotent stem cells and their differentiated derivatives. We have demonstrated that allogeneic ESCs do not produce a detectable immune response following their injection into the injured tendon in a small scale in vivo study. Furthermore, undifferentiated ESCs and spontaneously differentiated ESCs do not stimulate the proliferation of co-cultured allogeneic peripheral blood mononuclear cells in vitro. However, more detailed studies on the immune properties of ESC -derived tendon cells and the effect of an inflammatory environment are required.

Thu 12 Oct 13:00: Biomolecular condensates and their implications for neurodegenerative disease

Biomolecular condensates and their implications for neurodegenerative disease

Cells organize many of their biochemical reactions by formation and dissolution of non-membrane-bound compartments. Recent experiments show that a common mechanism for such biochemical organization is phase separation of unstructured proteins to form liquid-like compartments. These liquid-like compartments can be described by principles elucidated from condensed-matter physics and are therefore termed biomolecular condensates. I will discuss the relationship between the formation of liquid like compartments, and the onset of aggregated-protein pathology that is commonly observed in neurodegenerative diseases.

Undecidability in geometry and topology

There is a beautiful tension in topology between positive classification theorems and negative “no-go” theorems. The positive results come from geometry, and often derive ultimately from analysis. The negative results, by contrast, come from undecidability results in logic. I’ll give a survey of the history of this tension, and mention the highlight theorems — examples include Markov’s theorem that 4-manifolds cannot be classified (on the negative side), and Perelman’s Geometrization Theorem in dimension 3 (on the positive side). I’ll then go on to describe some recent undecidability results, which limit possible computations in matrix groups. This is joint work with Martin Bridson.

From All Talks (aka the CURE list). Published on Sep 12, 2017.

Continuous inference for aggregated point process data

We introduce new methods for inference with count data registered on a set of aggregation units. Such data are omnipresent in epidemiology due to confidentiality issues: it is much more common to know the county in which an individual resides, say, than know their exact location in space. Inference for aggregated data has traditionally made use of models for discrete spatial variation, for example conditional autoregressive models (CAR). We argue that such discrete models can be improved from both a scientific and inferential perspective by using spatiotemporally continuous models to directly model the aggregated counts. We introduce methods for delivering (limiting) continuous inference with spatitemporal aggregated count data in which the aggregation units might change over time and are subject to uncertainty. We illustrate our methods using real world examples and discuss the implementation of the methods on graphics processing units, which yields massive computational benefits.

Individual dynamic predictions using landmarking and joint modelling: validation of estimators and robustness assessment

After the diagnosis of a disease, one major objective is to predict cumulative probabilities of events such as clinical relapse or death from the individual information collected up to a prediction time, including usually biomarker repeated measurements. Several competing estimators have been proposed to calculate these individual dynamic predictions, mainly from two approaches: joint modelling and landmarking. These approaches differ by the information used, the model assumptions and the complexity of the computational procedures. It is essential to properly validate the estimators derived from the joint models and the landmark models, quantify their variability and compare them in order to provide key elements for the development and use of individual dynamic predictions in clinical follow-up of patients. Motivated by the prediction of two competing causes of progression of prostate cancer from the history of prostate-specific antigen, we conducted an in-depth simulation study to validate and compare the dynamic predictions derived from these two methods. Specifically, we formally defined the quantity to estimate and its estimators, proposed techniques to assess the uncertainty around predictions and validated them. We also compared the individual dynamic predictions derived from joint models and landmark models in terms of accuracy of prediction, efficiency and robustness to model assumptions. We show that these prediction tools should be handled with care, in particular by properly specifying models and estimators.

Efficient Photocatalytic Hydrogen Evolution via Band Alignment Tailoring: Controllable Transition from Type-I to Type-II

By Zhongzhou Cheng, Fengmei Wang, Tofik Ahmed Shifa, Chao Jiang, Quanlin Liu, Jun He from Small. Published on Sep 12, 2017.

Considering the sizable band gap and wide spectrum response of tin disulfide (SnS2), ultrathin SnS2 nanosheets are utilized as solar-driven photocatalyst for water splitting. Designing a heterostructure based on SnS2 is believed to boost their catalytic performance. Unfortunately, it has been quite challenging to explore a material with suitable band alignment using SnS2 nanomaterials for photocatalytic hydrogen generation. Herein, a new strategy is used to systematically tailor the band alignment in SnS2 based heterostructure to realize efficient H2 production under sunlight. A Type-I to Type-II band alignment transition is demonstrated via introducing an interlayer of Ce2S3, a potential photocatalyst for H2 evolution, between SnS2 and CeO2. Subsequently, this heterostructure demonstrates tunability in light absorption, charge transfer kinetics, and material stability. The optimized heterostructure (SnS2–Ce2S3–CeO2) exhibits an incredibly strong light absorption ranging from deep UV to infrared light. Significantly, it also shows superior hydrogen generation with the rate of 240 µmol g−1 h−1 under the illumination of simulated sunlight with a very good stability.

Multicolor Photo-Crosslinkable AIEgens toward Compact Nanodots for Subcellular Imaging and STED Nanoscopy

Aggregation induced emission (AIE) has attracted considerable interest for the development of fluorescence probes. However, controlling the bioconjugation and cellular labeling of AIE dots is a challenging problem. Here, this study reports a general approach for preparing small and bioconjugated AIE dots for specific labeling of cellular targets. The strategy is based on the synthesis of oxetane-substituted AIEgens to generate compact and ultrastable AIE dots via photo-crosslinking. A small amount of polymer enriched with oxetane groups is cocondensed with most of the AIEgens to functionalize the nanodot surface for subsequent streptavidin bioconjugation. Due to their small sizes, good stability, and surface functionalization, the cell-surface markers and subcellular structures are specifically labeled by the AIE dot bioconjugates. Remarkably, stimulated emission depletion imaging with AIE dots is achieved for the first time, and the spatial resolution is significantly enhanced to ≈95 nm. This study provides a general approach for small functional molecules for preparing small sized and ultrastable nanodots.

Touch: The sensory scaffold of development?

Touch is the first of our senses to develop. From the first prenatal trimester, touch provides the sensory scaffold on which we come to perceive our own bodies and sense of self. As well as bodily experiences, touch yields direct access to the external world of physical objects via haptics, and it also comprises key social-affective functions. And yet, surveys of the literature indicate that the numbers of articles examining tactile perceptual development (~7%) are dwarfed by those directed at the other senses. In this talk I will review research into tactile perceptual development across social, cognitive, emotional and affective domains, focussing particularly on research from my own laboratory addressing the early development of tactile contributions to own body perception. Key findings indicate that although tactile inputs have a developmental precedence compared to other senses, the developmental process by which touch becomes integrated with other sensory inputs extends well into postnatal development. Given this, I will argue that touch should be considered as central to the study of perceptual development rather than being neglected in the periphery where it has, until recently, very definitely resided.

Photoactuation Healing of α-FeOOH@g-C3N4 Catalyst for Efficient and Stable Activation of Persulfate

By Gong Zhang, Zhang Wu, Huijuan Liu, Qinghua Ji, Jiuhui Qu, Jinghong Li from Small. Published on Sep 12, 2017.

Inspired by living systems, the construction of smart devices that can self-heal in response to structural damage is a promising technology for maintaining the high activity and stability of catalysts during heterocatalytic reactions. Here this study demonstrates an ingenious platform that enabled efficient persulfate (PS) activation for contaminant degradation via integrating a catalyst with photoactuation regeneration. Under irradiation, it is unambiguously confirmed that the collective properties of a tailored FeOOH@C3N4 catalyst permit interfacial photoexcited electron transport from the photocatalyst substrate to needle-shaped FeOOH. This results in the simultaneous recovery of Fe(III) and optimization of the Fe(II)/Fe(III) ratio on FeOOH surface during PS activation process, so that the healed chemical structure ensures that subsequent PS activation remains unimpaired. Aqueous organic contaminant (bisphenol A) oxidation efficacy in this system is almost 20 times higher than for photo- or Fenton-oxidation alone. This work highlights the concept of catalyst regeneration for stable reactive species generation in solution, which represents alternative application of photocatalysis for practical environmental remediation. Further, the photoactuation healing approach can be expanded into various domains, such as material fabrication or chemical synthesis.

To chemical structural damage in persulfate (PS) activation process, a photosystem that can autonomously regenerate ferrous species is devised for the high PS activation performance. The collective properties of α-FeOOH@cabron-ring-C3N4 permit the efficient interfacial excited electrons transport from C3N4 to FeOOH, synchronously healing Fe(III) and optimize Fe(II)/Fe(III) ratio, so that render to enough active sties to make PS activation persistent.

Encapsulated Vanadium-Based Hybrids in Amorphous N-Doped Carbon Matrix as Anode Materials for Lithium-Ion Batteries

By Bei Long, Muhammad-Sadeeq Balogun, Lei Luo, Yang Luo, Weitao Qiu, Shuqin Song, Lei Zhang, Yexiang Tong from Small. Published on Sep 12, 2017.

Recently, researchers have made significant advancement in employing transition metal compound hybrids as anode material for lithium-ion batteries and developing simple preparation of these hybrids. To this end, this study reports a facile and scalable method for fabricating a vanadium oxide–nitride composite encapsulated in amorphous carbon matrix by simply mixing ammonium metavanadate and melamine as anode materials for lithium-ion batteries. By tuning the annealing temperature of the mixture, different hybrids of vanadium oxide–nitride compounds are synthesized. The electrode material prepared at 700 °C, i.e., VM-700, exhibits excellent cyclic stability retaining 92% of its reversible capacity after 200 cycles at a current density of 0.5 A g−1 and attractive rate performance (220 mAh g−1) under the current density of up to 2 A g−1. The outstanding electrochemical properties can be attributed to the synergistic effect from heterojunction form by the vanadium compound hybrids, the improved ability of the excellent conductive carbon for electron transfer, and restraining the expansion and aggregation of vanadium oxide–nitride in cycling. These interesting findings will provide a reference for the preparation of transition metal oxide and nitride composites as well.

Stretchable Electronic Sensors of Nanocomposite Network Films for Ultrasensitive Chemical Vapor Sensing

By Hong Yan, Mengjuan Zhong, Ze Lv, Pengbo Wan from Small. Published on Sep 12, 2017.

A stretchable, transparent, and body-attachable chemical sensor is assembled from the stretchable nanocomposite network film for ultrasensitive chemical vapor sensing. The stretchable nanocomposite network film is fabricated by in situ preparation of polyaniline/MoS2 (PANI/MoS2) nanocomposite in MoS2 suspension and simultaneously nanocomposite deposition onto prestrain elastomeric polydimethylsiloxane substrate. The assembled stretchable electronic sensor demonstrates ultrasensitive sensing performance as low as 50 ppb, robust sensing stability, and reliable stretchability for high-performance chemical vapor sensing. The ultrasensitive sensing performance of the stretchable electronic sensors could be ascribed to the synergistic sensing advantages of MoS2 and PANI, higher specific surface area, the reliable sensing channels of interconnected network, and the effectively exposed sensing materials. It is expected to hold great promise for assembling various flexible stretchable chemical vapor sensors with ultrasensitive sensing performance, superior sensing stability, reliable stretchability, and robust portability to be potentially integrated into wearable electronics for real-time monitoring of environment safety and human healthcare.

Revolving Vernier Mechanism Controls Size of Linear Homomultimer

A new kind of the Vernier mechanism that is able to control the size of linear assembly of DNA origami nanostructures is proposed. The mechanism is realized by mechanical design of DNA origami, which consists of a hollow cylinder and a rotatable shaft in it connected through the same scaffold. This nanostructure stacks with each other by the shape complementarity at its top and bottom surfaces of the cylinder, while the number of stacking is limited by twisting angle of the shaft. Experiments have shown that the size distribution of multimeric assembly of the origami depends on the twisting angle of the shaft; the average lengths of the multimer are decamer, hexamer, and tetramer for 0°, 10°, and 20° twist, respectively. In summary, it is possible to affect the number of polymerization by adjusting the precise shape and movability of a molecular structure.

Molecular Origin of Capacity Fade in Sodium Ion Batteries

As the demand for batteries for portable electronics, electric vehicles, and large-scale energy storage continues to increase, improvements in capacity, safety, lifetime, and particularly cost, to the current Li-ion standard are crucial. To address these needs, Na-ion batteries are a promising alternative for long-term energy storage sustainability in terms of both cost and natural abundance. For example, highly competitive layered Na-transition metal phosphate and oxide intercalation cathode materials offer a cost-effective alternative to their Li-ion counterparts. Further, Na-ion systems allow the replacement of expensive Cu current collectors with Al. However, robust candidates for anode materials in Na systems that offer equivalent capacities are lacking. As a result, progress in the development of suitable Na-ion batteries has been substantially stalled. Typical anode materials that are high performing for Li-ion systems, such as Si and graphite, do not reversibly store Na ions or suffer from low capacities, respectively. Otherwise, the high theoretical capacity for the formation of Na3P (2596 mAh/g) makes phosphorus-based materials promising candidates for anodes in Na-ion systems.  Indeed, by combining elemental phosphorus with conductive carbon, we can produce high capacity (2510 mAh/g) in Na-ion batteries. However, while we find that performance near that of theoretical capacity is reached in the first cycle, the capacity retention in phosphorus anodes is poor. Here, we use advanced nuclear magnetic resonance (NMR) techniques (ultrafast magic-angle spinning, variable temperature quadrupolar NMR , and two dimensional phase adjusted spinning sidebands experiments) to probe the phase chemistry and structural transformations that occur during electrochemical cycling to begin to understand the processes that are responsible for capacity fade in phosphorus anodes in Na-ion batteries. The insights gained from this work should help to guide the design and formulation of electrode materials used in next generation electrochemical energy storage devices.

Thu 02 Nov 13:10: How is continuous experience transformed into discrete memories?

From All Talks (aka the CURE list). Published on Sep 11, 2017.

How is continuous experience transformed into discrete memories?

Going through life, our senses perceive a continuous flow of information. Yet when we reminisce about the past, we remember experiences as discrete events. How does this occur? A leading theory (Event Segmentation Theory) suggests that salient changes result in prediction error (a failure to predict the immediate future), and are interpreted as boundaries between events. This, in turn, is thought to drive encoding of the preceding event to memory, while cleaning the slate for new information. I will discuss evidence supporting this theory, demonstrating that the hippocampus – a brain region strongly identified with formation of new memories – is particularly sensitive to the occurrence of event boundaries in naturalistic experience.

Thu 26 Oct 13:10: Did high levels of morphological flexibility facilitate colonisation of novel habitats during human evolution?

Did high levels of morphological flexibility facilitate colonisation of novel habitats during human evolution?

Homo sapiens has a global distribution, a remarkable achievement for a tropical ape. Adaptations enabling this colonisation are intriguing given suggestions that humans exhibits high levels of physiological and behavioural malleability associated with a ‘colonising niche’. Differences in body size/shape between members of the same species from different climates are well-known adaptations in mammals; could relatively flexible size/shape have been important to human species adapting to novel habitats? If so, at what point did this flexibility arise? To address these questions, a base-line for adaptation to climate must be established by comparison with suitable outgroups. Japanese macaques (Macaca fuscata) are the most northerly living non-human primates. They have great latitudinal spread and overlap with the historical distribution of prehistoric Jomon foragers, allowing matched latitude comparisons within monkeys and humans and making them an ideal outgroup for this study. We compare skeletons of M. fuscata from four different latitudes, including the most northerly and most southerly extremes of the species’ distribution. Initial results show inter-group differences in M. fuscata postcranial and cranial size and shape. Size varies more than shape, showing a strong, positive relationship with latitude. However, the very small size of the southern-most (island) sample may be affected by resource availability. Allometry-free shape shows geographic patterning and perhaps echoes some trends seen in human groups at high latitudes. These insights begin to provide a comparison for human adaptation to climatic diversity and the role of colonisation in shaping the evolution and dispersal of human species.

From All Talks (aka the CURE list). Published on Sep 11, 2017.

Taking control of flowing dense suspensions

Many soft matter systems including sandpiles and suspensions share the property of fragility: due to their history-dependent microstructural conformation, they can sustain stresses more effectively in some directions than in others. By continually updating the direction of flow one might maintain structure-stress incompatibility, thus inhibiting the formation of load-bearing structures. Here we provide evidence for fragility of this kind in a generic suspension and demonstrate, indeed, that the viscosities of such materials are consequently susceptible to time-varying flows. We thus propose several approaches to achieving `online’ viscosity control in the processing of such materials.

Spike timing in motor control

Last two-three decades have convinced the computational neuroscience community that sensory neurons encode information about the world not just in their firing rate, but also in the precise timing of their action potentials. However, whether this information is used by animals to actually drive behavior has never been shown. In this talk, in a time hopefully substantially shorter than a few decades, I will try to convince you that timing of spikes in multispike patterns, down to about 1 ms, is used by animals in their neural motor codes. I will focus primarily on control of vocalization and breathing in the Bengalese finch, a songbird. Finally, I will illustrate our recent attempts to decipher the Enigma of these motor codes.

Superaerophobic Ultrathin Ni–Mo Alloy Nanosheet Array from In Situ Topotactic Reduction for Hydrogen Evolution Reaction

By Qian Zhang, Pengsong Li, Daojin Zhou, Zheng Chang, Yun Kuang, Xiaoming Sun from Small. Published on Sep 11, 2017.

Hydrogen evolution reaction (HER) has prospect to becoming clean and renewable technology for hydrogen production and Ni–Mo alloy is among the best HER catalysts in alkaline electrolytes. Here, an in situ topotactic reduction method to synthesize ultrathin 2D Ni–Mo alloy nanosheets for electrocatalytic hydrogen evolution is reported. Due to its ultrathin structure and tailored composition, the as-synthesized Ni–Mo alloy shows an overpotential of 35 mV to reach a current density of 10 mA cm−2, along with a Tafel slope of 45 mV decade−1, demonstrating a comparable intrinsic activity to state-of-art commercial Pt/C catalyst. Besides, the vertically aligned assemble structure of the 2D NiMo nanosheets on conductive substrate makes the electrode “superaerophobic,” thus leading to much faster bubble releasing during HER process and therefore shows faster mass transfer behavior at high current density as compared with drop drying Pt/C catalyst on the same substrate. Such in situ topotactic conversion finds a way to design and fabricate low-cost, earth-abundant non-noble metal based ultrathin 2D nanostructures for electrocatalytic issues.

An ultrathin Ni–Mo alloy nanosheet array is synthesized through in situ topotactic reduction method. Attributing to the ultrathin 2D morphology, tailored alloy composition, and superaerophobic assembled structure, the Ni–Mo alloy nanosheets show faster electron transport and mass transfer toward hydrogen evolution reaction, which are even better than state-of-art Pt/C catalyst.

Recent results from Daya Bay reactor neutrino experiment and their implication on the Reactor Antineutrino Anomaly

The reactor antineutrino anomaly (RAA) has been puzzling reactor neutrino physics community since 2011. The RAA refers to the deficit of electron antineutrinos detected by reactor neutrino experiments compared with the number of electron antineutrinos predicted by state of the art reactor models. The Daya Bay experiment has utilized eight functionally identical underground detectors to sample reactor antineutrino fluxes from three pairs of nuclear reactors in South China, accruing the largest reactor antineutrino sample to date. This talk will summarize Daya Bay’s most recent result, which presents observations of correlations between reactor core fuel evolution and changes in the detected reactor antineutrino flux and energy spectrum. A 10 σ variation in IBD yield was found to be energy-dependent, rejecting the hypothesis of a constant antineutrino energy spectrum at 5.1 standard deviations. While measurements of the linear variation with respect to the fuel content in the IBD spectrum show general agreement with predictions from recent reactor models, the measured linear variation with respect to the fuel content in the total IBD yield disagrees with recent predictions. This discrepancy indicates that an overall deficit in measured flux with respect to predictions does not result from equal fractional deficits from the primary fission isotopes 235U, 239Pu, 238U, and 241Pu. A 7 .8% discrepancy between the observed and predicted 235U yield suggests that this isotope may be the primary contributor to the reactor antineutrino anomaly.

Betrayal, Distrust, and Rationality: Smart Counter-Collusion Contracts for Verifiable Cloud Computing

Cloud computing has become an irreversible trend. There is a pressing need for verifiability: the cloud providers are external parties whose interests may not fully align with those of its clients, therefore they cannot be fully trusted. To exercise due diligence and gain greater confidence in computation outsourced to the cloud, clients need to be able to verify the correctness of the results returned. However, existing verifiable computation techniques all have a high overhead, thus if being deployed in the clouds, would render cloud computing more expensive than the on-premises counterpart, and would diminish the motivation for using the clouds.

In this talk, I will present our recent attempt to achieve verifiability at a reasonable cost, by leveraging game theory and smart contracts, which is a newly developed paradigm on top of the blockchain technology. In a nutshell, a client lets two clouds compute the same task, and uses smart contracts to stimulate tension, betrayal and distrust between the clouds, so that rational clouds will not collude and cheat. In the absence of collusion, verification of correctness can be done easily by crosschecking the results from the two clouds. We provide a formal analysis of the games induced by the contracts, and prove that the contracts will be effective under certain reasonable assumptions. By resorting to game theory and smart contracts, we are able to avoid heavy cryptographic protocols. The client only needs to pay two clouds to compute in the clear, and a small transaction fee to use the smart contracts. We also conducted a feasibility study that involves implementing the contracts in Solidity and running them on the official Ethereum network.

The talk is based on a recent paper in CCS 2017 , the full version of the paper can be accessed through https://arxiv.org/abs/1708.01171.

Fri 24 Nov 16:30: Metacontrol: The Yin and Yang of cognitive control

From All Talks (aka the CURE list). Published on Sep 07, 2017.

Metacontrol: The Yin and Yang of cognitive control

Traditional approaches to action control assume the existence of a more or less unitary control system that struggles with, and serves to overcome action tendencies induced by automatic processes. In this talk, I point out that and why these approaches fail to capture the complexity and dynamics of cognitive control. I describe an alternative approach that assumes that control emerges from the interaction of at least two counteracting forces: one system promoting persistence and the maintenance of action goals and another promoting mental and behavioral flexibility. I describe how this interaction might be shaped by various factors, including genetic predisposition, learning, personal experience, and the cultural context, and suggest a simple functional model (the Metacontrol State Model, MSM ) that explains how this shaping process works. Then I provide an overview of studies from various fields (including perception, attention, performance monitoring, conflict resolution, creativity, meditation, religion, and social cognition/behavior) that successfully tested predictions from the MSM .

Tue 07 Nov 13:00: Can social networks explain why females cheat?

From All Talks (aka the CURE list). Published on Sep 07, 2017.

Can social networks explain why females cheat?

Infidelity is common among bird species with biparental care and social monogamy, but we still do not know well why females take part in extra-pair behaviour. Males are expected to gain fitness from siring extra-pair offspring, because extra-pair fathers do not expend resources on parental care. This is, however, not the case for females who raise the resulting extra-pair young, and who may risk retaliation from their mate, and other potential costs, posing the question of why females take part in extra-pair matings. The indirect benefits hypothesis offers an explanation: by cheating, females obtain “good genes” that are better, or more compatible, for their offspring. However, this hypothesis is not well supported empirically, evidenced by two contradictory meta-analyses on the topic, and active discussion in the field. Recently suggested, novel, testable hypotheses provide a fresh perspective. These so-called non-adaptive hypotheses do not require female infidelity to be adaptive per se, but rather explain female infidelity as resulting from intra- and intersexual antagonistic pleiotropy. These hypotheses suggest sexually antagonistic pleiotropy, behavioural spill-over, and social network effects to be important. I will present results from my own long-term wild house sparrow population, and from experiments with captive sparrows.

From All Talks (aka the CURE list). Published on Sep 07, 2017.

Probabilistic and Deep Models for 3D Reconstruction

3D reconstruction from multiple 2D images is an inherently ill-posed problem. Prior knowledge is required to resolve ambiguities and probabilistic models are desirable to capture the ambiguities in the reconstructed model. In this talk, I will present two recent results tackling these two aspects. First, I will introduce a probabilistic framework for volumetric 3D reconstruction where the reconstruction problem is cast as inference in a Markov random field using ray potentials. Our main contribution is a discrete-continuous inference algorithm which computes marginal distributions of each voxel’s occupancy and appearance. I will show that the proposed algorithm allows for Bayes optimal predictions with respect to a natural reconstruction loss. I will further demonstrate several extensions which integrate non-local CAD priors into the reconstruction process. In the second part of my talk, I will present a novel framework for deep learning with 3D data called OctNet which enables 3D CNNs on high-dimensional inputs. I will demonstrate the utility of the OctNet representation on several 3D tasks including classification, orientation estimation and point cloud labeling. Finally, I will present an extension of OctNet called OctNetFusion which jointly predicts the space partitioning function with the output representation, resulting in an end-to-end trainable model for volumetric depth map fusion.

From All Talks (aka the CURE list). Published on Sep 06, 2017.

Brain mechanisms underlying the subjective experience of remembering

Remembering personally experienced events involves reactivating sensory and perceptual event features, and the thoughts and feelings we had when the event occurred, and integrating them into a conscious experience during retrieval. It makes possible a number of decision making abilities, such as distinguishing events that actually occurred from those we might have imagined or been told about. Although a great deal is known about the cognitive and neural processes that enable us to recall a word list, for example, considerably less is known about the processes underlying the subjective experience of remembering. In this talk, I will consider evidence from functional neuroimaging and patient lesion studies addressing the contribution of different brain regions to the subjective experience of remembering.

Passive Picoinjection Enables Controlled Crystallization in a Droplet Microfluidic Device

By Shunbo Li, Muling Zeng, Thembaninkosi Gaule, Michael J. McPherson, Fiona C. Meldrum from Small. Published on Sep 05, 2017.

Segmented flow microfluidic devices offer an attractive means of studying crystallization processes. However, while they are widely employed for protein crystallization, there are few examples of their use for sparingly soluble compounds due to problems with rapid device fouling and irreproducibility over longer run-times. This article presents a microfluidic device which overcomes these issues, as this is constructed around a novel design of “picoinjector” that facilitates direct injection into flowing droplets. Exploiting a Venturi junction to reduce the pressure within the droplet, it is shown that passive injection of solution from a side-capillary can be achieved in the absence of an applied electric field. The operation of this device is demonstrated for calcium carbonate, where highly reproducible results are obtained over long run-times at high supersaturations. This compares with conventional devices that use a Y-junction to achieve solution loading, where in-channel precipitation of calcium carbonate occurs even at low supersaturations. This work not only opens the door to the use of microfluidics to study the crystallization of low solubility compounds, but the simple design of a passive picoinjector will find wide utility in areas including multistep reactions and investigation of reaction dynamics.

A microfluidic device is presented that enables highly reliable, on-chip analysis of the precipitation of insoluble crystals in flowing droplets. At the heart of the device is a novel design of picoinjector which employs a Venturi junction to achieve injection into surfactant-stabilized droplets. Chip operation is conducted for calcium carbonate, and the many advantages over traditional device designs are demonstrated.

Tue 21 Nov 13:00: Crowding and the disruptive effect of clutter throughout the visual system The host for this talk is Dr Paul Bays

From All Talks (aka the CURE list). Published on Sep 05, 2017.

Crowding and the disruptive effect of clutter throughout the visual system

Our ability to recognise objects is impaired in cluttered scenes, even for objects that are clearly visible in isolation. This process, known as crowding, is most evident in peripheral vision where it disrupts the recognition of a range of visual stimuli (including orientation, motion, colour, and faces) across large spatial regions. Crowding also becomes elevated in foveal/central vision in visual disorders ranging from amblyopia to dyslexia.

Is there a common mechanism for these diverse effects? I will argue that ‘pooling’ models, which depict crowding as an unwanted combination of target and flanker elements, can indeed provide this. In peripheral vision, crowded errors are not random, but rather reflect the combined appearance of the target object and surrounding flankers. We observe a similar pattern of errors in the foveal crowding that affects children with amblyopia, which pooling models simulate closely. Similarly, although it has been argued that crowding disrupts face recognition in a manner unlike that of simpler objects, we find that simple pooling processes provide a more parsimonious account. Finally, I will demonstrate that crowding can independently disrupt judgements of colour and motion for the same target object, suggesting the existence of multiple instances of crowding. Although this finding challenges ‘higher level’ crowding approaches, it is easily explained by pooling models.

Biodegradable Microparticles for Simultaneous Detection of Counterfeit and Deteriorated Edible Products

By Ivan Rehor, Sophie van Vreeswijk, Tina Vermonden, Wim E. Hennink, Willem K. Kegel, Huseyin Burak Eral from Small. Published on Sep 01, 2017.

In an era of globalized trade relations where food and pharmaceutical products cross borders effortlessly, consumers face counterfeit and deteriorated products at elevated rates. This paper presents multifunctional, biodegradable hydrogel microparticles that can provide information on the authenticity and the potential deterioration of the tagged food or pharmaceutical formulations. These microparticles integrate spatially patterned authenticity code with two sensors—the first one detects possible presence of pathogenic microbes through monitoring pH while the second one identifies products stored above optimal temperatures via optical monitoring of the microparticle degradation. Particles are synthesized from a biocompatible polymer and a photoinitiator, dextran modified with 2-hydroxyethylmethacrylate and riboflavin, respectively, using a continuous, high throughput method stop-flow lithography. The proposed synthesis approach also enables crosslinking with visible light bringing about additional flexibility to flow lithography. Model liquid and solid food and pharmaceutical products are successfully labeled with microparticles and the functionality of the sensors in aqueous solutions is demonstrated.

Biodegradable hydrogel microparticles are presented protecting consumers from counterfeited, contaminated, or deteriorated food and pharmaceutical products. Microparticles contain a spatially patterned authenticity code. Furthermore, a microbial contamination sensor and storage temperature sensor are incorporated into the microparticle structure. Stop-flow lithography, used for microparticle synthesis allows for their affordable large scale production, required for their use in industrial scale.

Argon-Plasma Reinforced Superamphiphobic Fabrics

By Shuai Liu, Hua Zhou, Hongxia Wang, Weidong Yang, Hao Shao, Sida Fu, Yan Zhao, Deqi Liu, Zhihua Feng, Tong Lin from Small. Published on Sep 01, 2017.

A novel method for preparing durable superamphiphobic fabrics is reported, which involves preapplying a solution consisting of perfluoroalkyl acrylate, epoxide-containing silane, and silica nanoparticles onto fabric and subsequent argon-plasma treatment. The coated fabrics show superphobic to both water and oil fluids (surface tension >21.5 mN m−1). The coating is durable to withstand repeated laundries and multicycles of abrasion without apparently altering the superamphiphobicity. The coating is also very stable in boiling water, strong acid, and base, but has little effect on the fabric handle and air permeability. The argon-plasma-enhanced coating may offer a facile way to prepare durable superamphiphobic fabrics.

Mesoscopic-Functionalization of Silk Fibroin with Gold Nanoclusters Mediated by Keratin and Bioinspired Silk Synapse

By Yao Xing, Chenyang Shi, Jianhui Zhao, Wu Qiu, Naibo Lin, Jingjuan Wang, Xiao Bing Yan, Wei Dong Yu, Xiang Yang Liu from Small. Published on Sep 01, 2017.

Silk fibroin (SF) offers great opportunities in manufacturing biocompatible/partially biodegradable devices with environmental benignity and biomedical applications. To obtain active SF devices of next generation, this work is to demonstrate a new functionalization strategy of the mesoscopic functionalization for soft materials. Unlike the atomic functionalization of solid materials, the meso-functionalization is to incorporate meso-dopants, i.e., functional molecules or nanomaterials, quantum dots, into the mesoscopic networks of soft materials. In this work, wool keratin (WK) molecules were adopted as mediating molecules to incorporate gold nanoclusters (AuNCs), into the mesoscopic networks of SF. It follows from our analyses that the β-crystallites between WK and SF molecules establish the binding between WK@AuNCs and the SF networks. The incorporated WK@AuNCs are electron rich and serve as electronically charged nano particles to bridge the growth of Ag filaments in bio-degradable WK@AuNCs–SF memristors. The meso-functionalization can greatly enhance the performance of SF materials and endows them with new functionalities. This can be highlighted by biocompatible/partly degradable WK@AuNCs functionalized SF resistive random-access memories, having the enhanced resistive switching memory performance, and the unique synapse characteristics and the capability of synapse learning compared with neat SF devices, and of great importance in nonvolatile memory, analog circuits, and neuromorphic applications.
