Biointegrated Multilayer Stretchable OLED Platform With Strain‐Decoupled Architecture for Durable Phototherapeutic Applications

Advanced Science, EarlyView.
A multilayer stretchable organic light‐emitting diode (SOLED) patch enables conformal, high‐fill‐factor phototherapeutic illumination through vertically decoupled electrodes and robust encapsulation. The textile‐based SOLED platform delivers stable skin‐contact red light for wearable phototherapy and 5‐aminolevulinic acid (ALA)‐mediated photodynamic ...

Unifying Scaling Relations and Multiple Reaction Mechanisms for Screening Transition Metal‐Doped Co3O4 for Oxygen Evolution Reaction

Angewandte Chemie, EarlyView.
Doped Co3O4 climbs a mechanistic volcano: transition‐metal substitution reshapes the OER activity landscape, while multiple competing reaction mechanisms govern the volcano trends across different dopants. ABSTRACT Accelerating the discovery of oxygen‐evolution reaction (OER) catalysts requires high‐throughput screening strategies combining descriptor ...
