Stability of Supported Pd-based Ethanol Oxidation Reaction Electrocatalysts in Alkaline Media

This study demonstrates that while Sn and Fe additives enhance the activity and stability of Pd-based electrocatalysts for ethanol oxidation in alkaline media, Nb additives induce severe dissolution that destabilizes the catalyst, highlighting the critical need to evaluate additive stability during the design phase for direct alcohol fuel cell applications.

Impact of charge transition levels on grain boundary properties in acceptor doped oxide ceramics: A phase-field study

This study introduces a defect-chemistry-consistent phase-field model explicitly coupled with charge transition levels to demonstrate how these levels govern space-charge layer formation, modulate grain boundary migration kinetics through rapid hole transport, and dictate the distinct properties of slow and fast boundaries in Fe-doped SrTiO₃.

Biogenic bubbles enable microbial escape from physical confinement

This study reveals that immotile microbial colonies, such as yeast, can achieve long-range dispersal in physically confining environments by metabolically generating CO2_2 bubbles that fracture the surrounding matrix and hydrodynamically entrain cells, establishing a novel mode of population-scale motion termed "metabolically driven active matter."

Optical Hall absorption sum rule and spectral compensation in time-reversal-breaking moiré and Hofstadter systems

This paper establishes a first-frequency-moment optical Hall absorption sum rule for time-reversal-breaking systems, demonstrating that it vanishes for zero-field moiré topological bands while taking a universal value determined by magnetic flux in Hofstadter models, thereby providing a rigorous framework to link low- and high-frequency spectral contributions and diagnose Landau-level mixing.
