Giant Berry‐phase‐Driven X‐Ray Beam Translations in Strain‐Engineered Semiconductor Crystals

open access: yesAdvanced Materials, EarlyView.
Due to the Berry‐phase effect, X‐rays propagating in deformed crystals undergo large translations, interesting for X‐ray optics applications. Here, the lattice expansion observed upon H irradiation of dilute‐nitride semiconductors is exploited to engineer the deformation landscape of selectively hydrogenated GaAsN epilayers.

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

open access: yesAdvanced 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 ...

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

open access: yesAdvanced Science
Cadmium (Cd) is a heavy metal that exhibits strong carcinogenic properties and promotes breast cancer (BC) progression. Autophagic flux dysfunction is involved in Cd‐induced BC progression, but the underlying molecular mechanisms remain unclear. Here, it

Adaptive Twisting Metamaterials

open access: yesAdvanced 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.

A single-cell transcriptomic landscape of cadmium-hindered brain development in mice

open access: yesCommunications Biology
The effects of neurotoxicant cadmium (Cd) exposure on brain development have not been well elucidated. To investigate this, we have herein subjected pregnant mice to low-dose Cd throughout gestation.
