No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Modular Interfacial Engineering via Nanofiber‐Reinforced Hydrogels for Stabilizing Zn Anodes Toward High‐Performance Zn‐Based Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Inspired by reinforced concrete casting, a modular interfacial engineering strategy was developed by integrating a rigid polyacrylonitrile fiber skeleton with an ion‐regulating hydrogel matrix. This composite interface homogenizes Zn2+ flux, accelerates ion transport, and stabilizes Zn deposition while suppressing hydrogen evolution and corrosion ...
