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

open access: yesAdvanced 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

open access: yesAdvanced 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.

Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

open access: yesAdvanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...

Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

open access: yesAdvanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing
