Neutral‐pH Electropolymerization of Aniline on Hierarchically Porous Laser‐Induced Graphene Electrodes for Dual Biosensing

Advanced Materials Technologies, EarlyView.
Neutral‐pH electropolymerization of aniline on laser‐induced graphene (LIG) produces stable, brush‐like polyaniline coatings without requiring acidic conditions. The resulting PANI–LIG electrodes exhibit enhanced electroactive surface area, efficient charge transfer, and dual sensing capability for β‐blockers and pH, providing a scalable platform ...

Ultra‐Thin Hybrid Ion Exchange Interlayer for High Performance Aqueous Zn Metal Batteries

Advanced Science, EarlyView.
An ultra‐thin SPEEK/FCD ion‐exchange interlayer modulates the Zn2+ solvation environment (–SO3−), provides ion‐exchange pathways that homoginized the Zn2+ flux, and via F‐rich chemistry forms in situ ZnF2 that suppresses parasitics and stabilizes the interface; its integrity relieves interfacial stress.
