Highly‐Conductive Mixed PEO/PAN‐Based Membranes for Solid State Li‐Ion Batteries via Electro‐Spinning and Hot‐Press Synthesis Routes

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.
Powder diffraction pattern of hot‐pressed polythylene oxide/ polyacrylonitrile polymerelectrolyte composites. Polyethylene oxide (PEO)‐based solid polymer electrolytes (SPEs) have been extensively studied for all solid‐state batteries (ASSBs) but still suffer from low thermal stability and ionic conductivity.

Coupled Ferroelectric–Photoelectrochemical in Water Reduction Over BiFeO3 Thin Film Heterostructure Modulated by Rare‐Earth Doping

Advanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
Gd‐doped BFO (BGFO) exhibits a ∼2‐order reduction in leakage current owing to its lowest content of oxygen vacancies. This leads to a ∼2.5‐fold increase in remnant polarization. These improvements in BGFO effectively boost charge separation and transportation, resulting in the greatest incident photon‐to‐current efficiency of 12.9 ± 0.73% and a ∼1.5 ...

Spatially‐Controlled Planar Guided Crystallization of Low‐Loss Phase Change Materials for Programmable Photonics

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
The concept of spatially‐controlled planar guided crystallization is a novel method for programming the growth of optically homogeneous low‐loss Sb2S3 phase‐change material (PCM), leveraging the directional crystallization within confined channels.

Aligned Nanostructures Resolve Zn2+ Transport Bottlenecks via Interfacial Kinetics–Diffusion Coupling in Aqueous Zinc‐Ion Batteries

Advanced Science, Volume 13, Issue 7, 3 February 2026.
It is revealed that limited solid‐state Zn2⁺ diffusion within the cathode leads to interfacial Zn2⁺ accumulation, forming a transport bottleneck that distorts Zn2⁺ flux directionality. Through advanced analytical techniques, including in situ electrochemical impedance spectroscopy (EIS), distribution of relaxation time (DRT) analysis, and COMSOL ...
