Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

Advanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Adaptive Twisting Metamaterials

Advanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Light‐Induced Entropy for Secure Vision

Advanced Materials, EarlyView.
This work realized a ternary true random number generator by exploiting stochastic traps emerging within multiple junction interfaces, and quantitatively validated the generation of high‐quality random numbers. Furthermore, it successfully demonstrated diverse applications, including AI‐resilient image security, thereby providing a valuable guide for ...

Wafer‐Scale Synthesis of Molecularly Engineered 2D Covalent Organic Framework Films for Highly‐Sensitive and Rapid‐Response Humidity Sensing

Advanced Materials, EarlyView.
We report molecularly engineered 2D COF films for high‐performance humidity sensors. The developed COFTPT‐THTA ultrathin film features triazine‐functionalized π‐conjugated backbones and high‐density surface hydroxyl groups. This unique architecture facilitates an electron‐proton coupled transport mechanism.

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

Advanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...
