Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

Advanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.

Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...
