Multiscale Interfacial Engineering Enables Robust Reconstituted Wood
Advanced Science, EarlyView.Conventional adhesives used in wood composites create heterogeneous interfaces that cause stress concentration under humid or aqueous conditions, thereby compromising long‐term stability. A synergistic strategy integrating interfacial reconstruction and water‐induced regeneration transforms heterogeneous interfaces into homogeneous ones with ...

Advanced Science, EarlyView.This work establishes an MXene/TiO2 Schottky heterointerface for non‐thermal sonocatalysis. Interface‐confined cavitation and dynamic Ti3+/V₀ shuttles drive charge transport and reactive oxygen species (ROS) generation. The platform achieves 3‐log pathogen reduction while retaining heat‐labile nutrients in complex food matrices, redefining sonocatalyst
