Activating a Metallization Switch for Record Hydrogen Evolution in Single‐Atom Modified Polar MOF Piezocatalysts

Advanced Materials, EarlyView.
ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

On the theory of superconductivity in ferromagnetic superconductors with triplet pairing

, 2004
We point out that ferromagnetic superconductors with triplet pairing and strong spin-orbit coupling are even in the simplest case at least two-band superconductors.

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 ...
