Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Biomineral‐Inspired Organic/Inorganic Colloidal Liquid‐Crystalline Hybrids for Photoresponsive Adhesion

Advanced Functional Materials, EarlyView.
A new class of photoresponsive liquid‐crystalline (LC) adhesives based on biomineral‐inspired organic/inorganic colloidal hybrids is reported. These colloidal LC materials are formed by hybridization of a hydroxyapatite nanorod with azobenzene‐based forklike molecules.

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...
