Electron‐Induced Molecular Programming Drives Interfacial Chemistry for Ah‐Level Zinc Batteries

Advanced Materials, EarlyView.
We establish an electron‐driven molecular programming strategy that converts spontaneous solid electrolyte interphase formation into a bonding‐defined interfacial architecture. Coordinative integration of p‐bromoaniline with ZnF2 forms a dipole‐regulated molecular lock that reconfigures interfacial electrostatics, suppresses parasitic water reactions ...

Evidence for strong lattice effects as revealed from huge unconventional oxygen isotope effects on the pseudogap temperature in La$_{2-x}$Sr$_{x}$CuO$_{4}$

, 2016
The oxygen isotope ($^{16}$O/$^{18}$O) effect (OIE) on the pseudogap (charge-stripe ordering) temperature $T^{\ast}$ is investigated for the cuprate superconductor La$_{2-x}$Sr$_{x}$CuO$_{4}$ as a function of doping $x$ by means of x-ray absorption near ...

Undercoordinated Molybdenum Catalysts Enable Ultrafast Quasi‐Solid Sulfur Chemistry in Sodium‐Sulfur Batteries

Advanced Materials, EarlyView.
An unsaturated coordination chemistry strategy activates a quasi‐solid‐state redox pathway by strengthening NaPSs adsorption and accelerating redox conversion kinetics, thereby overcoming the kinetic bottlenecks that limit high‐rate performance. In situ transmission electron microscopy, combined with newly developed Na‐ion diffusion descriptors ...

Powder‐to‐Film Conversion of Nickel Single‐Atom Catalysts into Binder‐Free and Resistant Electrodes

Advanced Materials Interfaces, EarlyView.
A reproducible strategy is reported for fabricating standalone thin‐film electrodes composed of CNx‐supported Ni single‐atom catalysts. The resulting binder‐free electrodes exhibit robust stability, enhanced charge transfer, and superior electrochemical performance, offering scalable opportunities for applications in electrochemistry. ABSTRACT Although
