Advanced Science, EarlyView.A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

Single‐Crystalline Borate Covalent Organic Frameworks for Solid‐State Lithium Metal Batteries
Advanced Science, EarlyView.Advancing lithium metal batteries demands novel solid‐state electrolytes. Covalent organic frameworks (COFs) offer high ion conduction via porosity and functional groups. We synthesized single‐crystalline 3D borate COF with 8.1 mS cm−1 conductivity and 0.98 Li+ transference.

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion
Advanced Science, EarlyView.In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...

Advanced Science, EarlyView.The diagram depicts the endothelial‐protective mechanism of magnesium lithospermate B (MLB) in sepsis‐associated lung injury. MLB binds GPX4 at Gly79, disrupts its interaction with FUNDC1, prevents mitophagy‐mediated GPX4 degradation, restores mitophagic flux, reduces ROS, and limits ferroptosis.
