Exchange Length Tailored Magnetic Resonance for Broadband Absorption in FeCo‐Based Alloys

open access: yesAdvanced Science, EarlyView.
To break the high‐frequency magnetic loss bottleneck in soft magnetic alloys, a magnetic exchange length (Lex)‐guided strategy is proposed. Cu doping increases Lex and intergranular coupling, which effectively reduces magnetic anisotropy and pushes the exchange resonance to 12.0 GHz.

Optical Charge Trap Memory Based on Graphene/ZnO Heterostructures for Long‐Term Retention and Adaptive Learning

open access: yesAdvanced Electronic Materials, EarlyView.
A biocompatible graphene/ZnO optical charge trap memory (CTM) is reported with over 54 h retention, enabled by interfacial photodoping. Using transient absorption spectroscopy and electrical analysis, charge transfer quenching is elucidated and reveal that a large energy barrier at the interface is responsible for long‐term memory retention.

Stable Catholyte Interface Enables Practical Operation of Sulfide‐Based All‐Solid‐State Li Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A conformal fluorocarbon self‐assembled monolayer on Li6PS5Cl protects the solid electrolyte from degradation by polar solvents and moisture. This surface stabilization allows scalable slurry processing and stable cycling even under low pressure, offering a practical pathway to high‐performance all‐solid‐state batteries. Abstract Achieving chemical and

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Decoding Short‐Range Order in Amorphous Two‐Dimensional Nanosheets for Efficient and Durable Ampere‐Level Seawater Electrolysis: A Case Study of Amorphous Ni(OH)2

open access: yesAdvanced Energy Materials, EarlyView.
This work uncovers the atomic‐scale origins of exceptional HER performance in amorphous Ni(OH)2 nanosheets by combining atom probe tomography, DFT simulations, and operando spectroscopy. We identify distinct short‐range‐order motifs that accelerate water dissociation, proton transport, and hydrogen adsorption. Embedding Pt single atoms further enhances
