Advanced Functional Materials, EarlyView.High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth
Advanced Functional Materials, EarlyView.Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Self‐Refreshing Bi‐Based Active Sites for Efficient and Durable Electrochemical CO2 Reduction
Advanced Functional Materials, EarlyView.A self‐refreshing Bi‐based catalyst is developed through the fabrication of a novel basic bismuth nitrate pre‐catalyst, which exhibits differential active sites of Bi2O2CO3 at low potentials and metallic Bi phases at high potentials, self‐repairing capability, and thus wide‐potential‐window efficiency and ultralong durability toward electrochemical CO2
