Graphene Quantum Dot‐Induced Microstrain for Framework Stabilization of High‐Entropy Prussian Blue Analog in High‐Current Alkaline Hydrogen Evolution Reaction

Advanced Functional Materials, EarlyView.
The intrinsic distortion‐rich lattice of HEPBA with GQD‐enabled microstrain engineering establishes a mechanistic route toward high‐performance alkaline hydrogen evolution reaction. HEPBA inherently feature heterogeneous local coordination environments arising from multimetal incorporation, while properly introducing GQD during coprecipitation ...

Tuning Redox Dynamics in Cu‐Based Electrocatalysts: Effect of Secondary Metals

Advanced Functional Materials, EarlyView.
Advanced analysis of operando X‐ray absorption spectroscopy data reveals that secondary metals affect the redox processes in Cu‐based catalysts for electrocatalytic CO2 reduction. This influences the amount of oxides formed under pulsed reaction conditions and the distribution of reaction products.

Extraordinary n‐type Tellurium‐Free Thermoelectric Performance of Y‐Doped BiSe via Synergistic Effect of Vacancies and Band Engineering

Advanced Functional Materials, EarlyView.
Yttrium doping in Sb‐alloyed BiSe synergistically induces Bi vacancies and flattens conduction bands, simultaneously slashing lattice thermal conductivity by 50% and boosting the power factor. The optimized n‐type Bi0.64Sb0.3Y0.06Se delivers a peak zT of 0.91 at 393 K (average zT 0.76, 300–523 K) and an 8‐pair module with 4.6% conversion efficiency ...

Hierarchical Primary‐Secondary Coordination Synchronizes Ion Flux and Sulfur Redox in Solid Polymer Electrolytes

Advanced Functional Materials, EarlyView.
Hierarchical coordination engineering redistributes Li+ from anion‐dominated pairing toward polymer‐mediated binding. Strong primary sites promote salt dissociation, while distributed secondary sites sustain dynamic hopping pathways. This coordination landscape couples ion flux with polysulfide conversion, suppresses transport‐conversion decoupling ...
