Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

Advanced Materials, Volume 37, Issue 32, August 14, 2025.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Pressure‐induced quenchable superhard tetrahedral amorphous phase of BC4N

Journal of the American Ceramic Society, Volume 108, Issue 7, July 2025.
• A quenchable tetrahedral amorphous phase with a high fraction of sp3 bonding is observed. • The tetrahedral phase exhibits ultra‐high incompressibility and a high Vickers hardness, classifying it as a superhard material. • The material demonstrates semiconducting behavior with a narrow bandgap.
