Orientation Engineering in Flexible Ag2Se‐Based Thermoelectric Films

open access: yesAdvanced Science, EarlyView.
We comprehensively review recent advances in highly oriented Ag2Se films. We propose two practical metrics to quantitatively benchmark their application potential and establish a unified framework that elucidates the orientation‐dependent charge transport mechanism in Ag2Se‐based films.

Electropulse‐Driven Dislocation Evolution in Sub‐10 nm Metallic Nanocrystals

open access: yesAdvanced Science, EarlyView.
Atomic‐scale TEM imaging reveals how nanosecond electropulses drive dislocation evolution in sub‐10 nm metallic nanocrystals. Enhanced electron scattering at structural heterogeneities nucleates dislocation loops and dipoles, which then repeatedly interact and annihilate, causing dislocation density fluctuations or structural disordering.

Surface Neuronal‐Like Structuring of High‐Strength CFRP for Enhanced Electromagnetic Interference Shielding

open access: yesAdvanced Science, EarlyView.
This study elucidates the microstructural evolution at the material interface of Ni‐plated plain‐weave carbon fiber fabric following vacuum heat treatment at 500°C–900°C under different current densities, as well as the mechanism underlying the synergistic enhancement of electromagnetic shielding and ductility.
