Molecular Conversion of Thermally Stable Cu‐Ag Networks for Mechanically Robust Printed Electronics

Advanced Science, EarlyView.
An air‐processable Cu–Ag reactive ink enables in situ formation of an Ag‐surface‐enriched Cu conductive network. Optimized Ag distribution suppresses Cu oxidation while preserving continuous electrical pathways, allowing printed conductors to achieve high conductivity, reduced migration, and stable operation at extreme temperatures up to 800 °C in air.

Surface‐Selective Pt Enrichment for Stabilizing Ultrathin 2D PtCu Nanosheets Toward Durable Oxygen Reduction

Advanced Science, EarlyView.
Ultrathin 2D alloy nanosheet catalysts could offer exceptional catalytic activity but suffer from severe structural instability. Here, a surface‐selective Pt enrichment strategy via galvanic replacement effectively stabilizes PtCu Nanosheets while preserving their ∼ 1 nm thickness and (111) facets.

Localized Hydrogen Release Driven by Mg–Pd Microgalvanic Cells from 3D‐Printed Microneedles Reverses Redox Homeostasis for Psoriasis Treatment

Advanced Science, EarlyView.
A 3D printing microneedle (MP‐MN), loading magnesium‐based micro‐galvanic cells (MP), is designed for improving psoriasis. H2 generated from MP‐MN scavenges ROS and •OH, actives NRF2‐KEAP1 pathway, and decreases inflammation, thereby effectively restoring the oxidative stress homeostasis of psoriatic skin and suppressing the excessive proliferation of ...
