Formation‐Stage Interfacial Regulation of δ‐MnO2 Enables Stable and Reversible Aqueous Zn‐Ion Storage

open access: yesAdvanced Science, EarlyView.
Precursor‐embedded Fe regulates the nucleation and growth of δ‐MnO2, enabling a more accessible and stable Zn‐storage interface with accelerated kinetics and suppressed Mn dissolution, while preserving the intrinsic Mn redox chemistry. ABSTRACT Layered δ‐MnO2 is a promising cathode for aqueous zinc‐ion batteries, yet its practical application remains ...

Multiband Optical Physical Unclonable Functions Based on Mixed‐Phase Multilevel Emissive Perovskites

open access: yesAdvanced Science, EarlyView.
In this paper, sustainable multiband optical PUFs were developed by constructing heterostructures between lead‐free phase‐mixed perovskites and cellulose fibers via a water‐assisted drop‐casting process. Cesium manganese bromide perovskites provide an environmentally benign composition while exhibiting excitation‐dependent multilevel photophysical ...

Phase‐Programmed Microneedles Enable Sequential Hydrogen and Quercetin Release for Scar‐Reduced Regeneration of Burn Wounds

open access: yesAdvanced Science, EarlyView.
A phase‐programmed microneedle patch, comprising a poly (lactic‐co‐glycolic acid) (PLGA) shell and a sulfobutylether‐β‐cyclodextrin (SBECD) core, is designed for sequential hydrogen and quercetin release for scar‐reduced regeneration of burn wounds. ABSTRACT Burn wounds complicated by bacterial infection and fibrotic scarring remain a major clinical ...

Intelligent Polymer Electrolytes for Next‐Generation Zinc‐Based Energy Storage Devices

open access: yesAdvanced Science, EarlyView.
Intelligent polymer electrolytes are organized into a three‐level hierarchy that advances zinc‐based energy storage from passive ion conduction toward active, adaptive, and intelligent operation. Molecular regulation of Zn+ coordination, water activity, desolvation, ion flux, and interfaces underpins adaptive self‐healing, anti‐freezing, adhesion, and ...
