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.

Cavity‐Enhanced Eye‐Readable Detection of 0.1% H2 via Active Modulation of Charge‐Transfer Plasmons

open access: yesAdvanced Science, EarlyView.
A cavity‐structured nanoparticle sensor is developed for highly sensitive, eye‐readable hydrogen detection. Its excellent colorimetric response arises from a hydrogen‐induced charge‐transfer mechanism: reduction of the dielectric oxide shell in H2 triggers a transition from the plasmonic gap mode to the charge‐transfer plasmon mode.

Electrocatalytic C─C Bond Formation Via Cyanide Interception of CO2 Reduction Intermediates

open access: yesAdvanced Science, EarlyView.
ABSTRACT Electrochemical CO2 reduction offers a sustainable route to convert greenhouse gas into high‐value‐added chemicals, yet product distributions remain largely limited to simple C1‐C3 molecules. Here, we report a new reaction in which CO2 reduction intermediates undergo direct C‐C coupling with an external carbon nucleophile under electrochemical

Anion‐Driven Surface Reconstruction Enables Direct Regeneration of LiCoO2 Cathode Material

open access: yesAdvanced Science, EarlyView.
The anion scpecies in molten salt systems critically govern the surface reconstruction of regenerated LiCoO2. LiOH−LiCl flux, featuring strong Cl− adsorption and facile dissociation, directs preferential relithiation on (003) facets and forms a Li−O enriched interface.

A New Ordered Transformation‐Induced Plasticity Enables Exceptional Strength and Ductility in a B2 Medium‐Entropy Alloy

open access: yesAdvanced Science, EarlyView.
A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior

Sodiophilic Na3Sb Framework‐Regulated Sodium Deposition and Interphase Evolution for Dendrite‐Free and Long‐Life Sodium Metal Batteries

open access: yesAdvanced Science, EarlyView.
An interconnected sodiophilic Na3Sb framework embedded within a metallic Na matrix enables uniform Na deposition by homogenizing Na+ flux and providing abundant nucleation sites. Simultaneously, the regulated interface promotes the formation of a stable, NaF‐rich inorganic interphase, collectively suppressing dendrite growth and enabling highly ...

Cavity‐Compatible Light Extraction in Top‐Emitting Microcavity OLEDs via a Gentle Internal Corrugation Layer and Resonance‐Matched Narrowband Emission

open access: yesAdvanced Science, EarlyView.
A gentle internal corrugation layer conformally reshapes the microcavity OLED stack, redistributing confined optical power toward extractable channels while preserving cavity‐controlled emission. Combined with optical clear resin and a resonance‐matched narrowband pTSF emissive system, this cavity‐compatible architecture delivers an external quantum ...
