A Cu2S/NiOOH Heterojunction Enables Highly Selective Ammonia‐to‐Nitrite Electrooxidation at Industrially Relevant Current Densities

Advanced Materials, EarlyView.
Cu2S/NiOOH heterojunction enables efficient ammonia electrooxidation coupled with hydrogen evolution. Interfacial electronic modulation of Ni sites promotes selective NH3‐to‐NO2− electrooxidation at high current density. In a membrane electrode assembly, Cu2S/NiOOH maintains over 90% Faradaic efficiency of nitrite at 800 mA cm−2, highlighting its ...

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites

Advanced Materials, EarlyView.
Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.
