Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Basal Plane Graphene Coated Zn Powder for High Performance Aqueous Zn Metal Batteries

Advanced Science, EarlyView.
A mechanofusion‐driven dry coating forms a hydrophobic graphene shell on Zn powder, stabilizing the electrode‐electrolyte interface. This basal‐plane‐rich protective layer modifies the Zn2+ solvation environment and promotes preferential growth along the (002) plane, suppressing dendrite and parasitic reactions.
