Article Abstract

This work presents a Joule-heating strategy to create thin proton exchange membranes (PEMs) with high proton conductivity and low H crossover. The treated PEMs assembled electrolyzer achieves a record current density of 3.72 A cm at 1.9 V with 1250 h durability at 2 A cm for water electrolysis.

Cell migration assays provide valuable insights into pathological conditions, such as tumor metastasis and immune cell infiltration, and the regenerative capacity of tissues. In vitro tools commonly used for cell migration studies exploit commercial transwell systems, whose functionalities can be improved through engineering of the pore pattern. In this context, we propose the fabrication of a transwell-like device pursued by combining the proton beam writing (PBW) technique with wet etching onto thin layers of polydimethylsiloxane (PDMS).

Pt coating has been considered a promising strategy to protect the Ti porous transport layer substrate in a proton exchange membrane electrolyzer from corrosion. However, despite significant advancements in understanding the composition, process, and structure of Pt coatings, the underlying causes of coating failure remains unclear. Here, we systematically investigate the failure processes of magnetron-sputtered Pt coatings on Ti substrates through ex situ electrochemical tests that simulate anode operational conditions.

The regulation of product selectivity in electrochemical CO reduction (ECOR) remains fundamentally constrained by the dynamic equilibrium between intermediate transport and surface coverage. In this study, we report a progress in catalytic architecture through precision-engineered Au@CuO yolk-shell tandem nanoreactors featuring dual-tunable parameters: cavity confinement dimensions and shell thickness gradients. This structural modulation enables dynamic control over both *CO intermediate enrichment and reaction pathway bifurcation.
