Tailoring Structure–Property Relationships in π‐Conjugated Heterocyclic Poly(arylene alkylene) Anion‐Exchange Membranes for High‐Performance Water Electrolysis

Advanced Science, EarlyView.
From passive to active ion transport: π‐conjugated heterocycles reconfigure the hydration environment and microphase morphology of p‐terphenyl‐based anion‐exchange membranes, enabling fast hydroxide transport and high‐performance water electrolysis. ABSTRACT Anion‐exchange membrane water electrolysis (AEMWE) is a promising technology for sustainable ...

Controlled Lattice Distortion and Lattice‐Strain‐Engineered CoCuIr Alloy toward Preferential Chlorine Tolerant Direct Seawater Electrolysis

Advanced Science, EarlyView.
A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.

Low-Complexity Autocorrelation-Based OFDM Detection Under Sub-Nyquist Sampling

IEEE Access
Sub-Nyquist sampling has emerged as an attractive approach for reducing the hardware complexity and computational burden associated with orthogonal frequency division multiplexing (OFDM) spectrum sensing. However, sampling below the Nyquist rate modifies

Dynamic Interfacial Charge Regulation for High‐Fidelity Broadband Circularly Polarized Light Detection

Advanced Science, EarlyView.
A photoelectrochemical circularly polarized light detector combines a multilayer chiral photonic film with a dynamically regulated BiVO4‐RGO‐MXene transducer. Broadband optical modulation from 360 to 830 nm is converted into stable electrical outputs through low‐noise solid‐liquid interfacial charge transfer, enabling self‐powered CPL discrimination ...

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

Advanced 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.

Mixed‐Valence Atomic‐Layer Iridium Patches Enhance Alkaline Hydrogen Evolution

Advanced Science, EarlyView.
Engineering iridium architectures on Cu3P nanowires reveals that atomic‐layer Ir patches form a mixed‐valence interfacial motif with an anisotropic electronic structure. This configuration balances water dissociation and hydrogen adsorption/desorption, delivering superior alkaline hydrogen evolution with a 27 mV overpotential and 1 A cm−2 operation in ...
