Chirality‐Driven Piezocatalysis in MOFs: Achieving Efficient Cocatalyst‐Free Hydrogen Evolution

Angewandte Chemie, EarlyView.
We report a chirality‐driven post‐synthetic modification strategy that grafts chiral L‐histidine (L‐His) onto the Hf6 clusters of MOF‐808(Hf), which significantly boosts the piezoelectricity and charge transfer efficiency, thus significantly enhancing the piezocatalytic performance of MOF‐808(Hf).

Dynamic Etching‐Induced Cl‐Terminated Ti3C2Clx/Ti3ZnC2 Heterostructure for Ammonia Electrosynthesis and Zinc‐Nitrogen Batteries

Advanced Science, EarlyView.
A stable Ti3C2Clx/Ti3ZnC2 heterostructure, fabricated by dynamic etching, exhibits outstanding electrocatalytic NRR activity (NH3 yield: 20.1 µg h−1 mg−1, FE: 38.1%) in alkaline media. The corresponding Zn‐N2 battery achieves a peak power density of 36.5 µW cm−2 and an NH3 yield of 13.1 µg h−1 mg−1, providing an advanced strategy for NH3 and ...

The effect of nonmetallic inclusions on hydrogen embrittlement.

Journal of the Society of Materials Science, Japan, 1987
The present work deals with the effects of nonmetallic inclusions on hydrogen assisted cracking (HAC) and its fracture morphology. Three point bending test was carried out, using hydrogen charged and uncharged specimens whose sulphur contents were changed in the range 10 to 510ppm.

Sliding Ferroelectricity Driven Spin‐Layertronics in Altermagnetic Multilayers

Advanced Science, EarlyView.
Integrating sliding ferroelectricity with altermagnetism enables nonvolatile electrical control of spin and layer degrees of freedom. In bilayer CuF2, interlayer translation reverses layer‐locked spin‐split bands, establishing a multifunctional “spin‐layertronic” platform.

A High‐Current‐Tolerant Multimetallic Phosphide Electrode for Alkaline Water Electrolysis Toward Industrial Conditions

Advanced Science, EarlyView.
A phosphide‐modified multimetallic HER electrode achieves industrial‐level performance with minimal noble‐metal content. It delivers 1.7 A cm−2 at 2.0 V in 6 M KOH at 70°C and operates stably for over 200 h at 500 mA cm−2. Phosphorus tuning of the electronic structure optimizes hydrogen adsorption, offering a durable, high‐rate pathway for alkaline ...
