Conductive Polymer Coatings Control Reaction Selectivity in All‐Iron Redox Flow Batteries

Advanced Materials, EarlyView.
Aqueous redox flow batteries are limited by the competing hydrogen evolution reaction (HER) at their negative electrodes. In this work, conductive polymers are conformally coated on porous carbonaceous electrodes to improve the reaction selectivity of hybrid all‐iron redox flow batteries.

Optimizing Perovskite Surfaces to Enhance Post‐Treatment for Efficient Blue Mixed‐Halide Perovskite Light‐emitting Diodes

Advanced Materials, EarlyView.
The halide postdeposition process is optimized by engineering blue mixed‐halide 3D perovskites with acetate‐rich surfaces. This engineered perovskite minimizes the washing effect of isopropanol, which slows down surface reconstruction and ultimately promotes the formation of a uniform mixed‐halide perovskite phase.
