Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5
Advanced Functional Materials, EarlyView.We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...

Ga–O–Pt Electronic Bridges Bypass Single‐Site Constraints for pH‐Universal Hydrogen Evolution
Advanced Functional Materials, EarlyView.Well‐defined oxygen‐bridged Ga–O–Pt catalysts are constructed for pH‐universal hydrogen evolution, highlighting the relationship between oxygen‐bridged electronic coupling, rapid surface hydrogen redistribution, and superior catalytic performance. ABSTRACT Single‐site descriptors often fail to capture hydrogen evolution on heterometallic interfaces ...

Advanced Functional Materials, EarlyView.A lead‐free tin‐based hybrid perovskite is designed in which stereochemically active lone‐pair electrons on tin distort the crystal lattice and break its symmetry. Blended into a flexible polymer, the material converts pressure into electricity at milliwatt‐scale power density and continues working far below freezing, powering a commercial wristwatch ...

Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities
Advanced Functional Materials, EarlyView.We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...
