Nature Materials, Published online: 22 May 2024; doi:10.1038/s41563-024-01904-1The authors demonstrate a programmable topological photonic chip with large-scale integration of silicon photonic nanocircuits and microresonators that can be rapidly reprogrammed to implement diverse multifunctionalities.

Nature Materials, Published online: 22 May 2024; doi:10.1038/s41563-024-01900-5Understanding the origin of photoinduced water splitting on TiO2 is crucial to control photocatalytic surface reactions. A photoexcited-hole-transfer-driven mechanism now shows that water dissociation is strongly coupled with dynamic lattice distortion (photoexcited phonons)...

Nature Materials, Published online: 20 May 2024; doi:10.1038/s41563-024-01901-4Although structurally ordered intermetallic nanocrystals are promising electrocatalysts for fuel cells, their high-temperature large-scale preparation has proved challenging. A low-melting-point-metal-induced bond strength weakening strategy to promote alloy catalyst ordering...

Nature Materials, Published online: 20 May 2024; doi:10.1038/s41563-024-01887-zQuantum coherent control of single-photon-emitting defect spins have been reported in hexagonal boron nitride, revealing that spin coherence is mainly governed by coupling to a few proximal nuclei and can be prolonged by decoupling protocols.
