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.

Origin of Excessive Ionization in Flames [PDF]
Nature, 1964 IT has been known for a long time that combustion reactions of the type occurring in flames are sometimes accompanied by an extremely high degree of ionization and excitation of the flame gas1. In fact, electron concentrations have been observed which are several orders of magnitude higher than the values given by Lindemann–Saha's equation which ...

Advanced Materials, EarlyView.Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.
