Revealing inter-cell water-gas-coupled transfer characteristics and degradation-driven evolution within large-scale fuel cell stacks

Hydrophobicity decay is a critical driving force behind the degradation of proton exchange membrane fuel cells. However, the cross-scale linkage between microscopic material-level hydrophobic degradation and macroscopic stack-level water-gas transfer behaviors remains largely obs...

Antiferrodistortive Matrix Engineering Reprograms Polarization Pathways for Ultrahigh Energy Storage at Moderate Electric Fields

ABSTRACT Relaxor ferroelectrics (RFEs) are promising dielectric materials for pulsed multilayer ceramic capacitors because of their rapid polarization response. However, under practical electric fields, polarization rapidly approaches saturation as polar nanoregions exhaust their...

Quasi‐Covalent Conductive Bridges in 2D Semimetal‐Semiconductor Contacts

ABSTRACT Achieving ultralow contact resistance in two‐dimensional transition metal dichalcogenide semiconductors remains a key bottleneck for further device scaling. Although all‐2D semimetal/semiconductor van der Waals (vdW) contacts effectively suppress metal‐induced gap states...
