Conformally coated scaffold design using water-tolerant Pr<sub>1.8</sub>Ba<sub>0.2</sub>NiO<sub>4.1</sub> for protonic ceramic electrochemical cells with 5,000-h electrolysis stability
Nature Energy, Published online: 01 July 2025; doi:10.1038/s41560-025-01800-1
Protonic ceramic electrochemical cells (PCECs) interconvert hydrogen and electricity and therefore have potential as long-duration energy storage systems, but the durability of these devices under industrially relevant conditions is limited. Here the authors report a PCEC that maintains low degradation rates throughout exceptionally long-term durability tests.

Vortex lasers through collective boundary scattering
Nature Nanotechnology, Published online: 01 July 2025; doi:10.1038/s41565-025-01970-9
Photonic crystals enclosed by a circular boundary enable single-mode vortex lasing through momentum-space hybridization of guided resonances — a collective phenomenon distinct from individual resonator physics.

Observation of chiral emission enabled by collective guided resonances
Nature Nanotechnology, Published online: 01 July 2025; doi:10.1038/s41565-025-01964-7
Chiral emission from collective guided modes is demonstrated within a photonic crystal slab, showing an example of collective oscillations in the momentum space.
