Fe3O4 nano-octahedra and SnO2 nanorods modifying low-Pd amount electrocatalysts for alkaline direct ethanol fuel cells

This study demonstrates that low-palladium electrocatalysts modified with Fe3O4 nano-octahedra and SnO2 nanorods significantly enhance ethanol oxidation activity and power density in alkaline direct ethanol fuel cells through a bifunctional mechanism and strong metal-oxide interactions, with the PdFe3O4/C ternary catalyst achieving the highest performance despite a 45% reduction in palladium content.

Symmetry-protected four double-Weyl fermions and their topological phase transitions in nonmagnetic crystals

This paper establishes a rigorous symmetry framework identifying 28 space groups that host exactly four double-Weyl fermions, proposes the chiral carbon allotrope THRLN-C $_{32}$ as a material realization, and elucidates its strain-driven topological phase transitions into various exotic or trivial states.

Double- $Q$ chiral stripe order in the anomalous Hall antiferromagnet CoNb $_3$ S $_6$

Using resonant elastic x-ray scattering with polarization analysis, the study reveals that the metallic antiferromagnet CoNb $_3$ S $_6$ hosts a novel non-coplanar double- $Q$ chiral stripe order driven by four-spin exchange interactions, which explains its anomalous Hall effect and offers new insights into unconventional magnetotransport in metallic antiferromagnets.

SiO $_2$ -mediated facile hydrothermal synthesis of spiroffite-type Co $_2$ Te $_3$ O $_8$

This paper demonstrates that using SiO $_2$ as a mineralizer enables the facile hydrothermal synthesis of spiroffite-type Co $_2$ Te $_3$ O $_8$ under milder conditions, while its combination with alkali carbonates induces silicon substitution and disorder that enhances low-temperature ferromagnetism.

Choosing a Suitable Acquisition Function for Batch Bayesian Optimization: Comparison of Serial and Monte Carlo Approaches

This paper compares serial and Monte Carlo batch acquisition functions for Bayesian optimization on synthetic and empirical datasets, concluding that the q-upper confidence bound (qUCB) is the most robust default choice for optimizing unknown black-box functions in up to six dimensions.

Persistence of Layer-Tolerant Defect Levels in ReS2

This study reveals that ReS2 exhibits unique layer-tolerant defect energy levels that remain invariant from monolayer to bulk due to the interplay of electronic minimization, structural relaxation, and weak interlayer coupling, establishing it as a robust platform for thickness-independent optoelectronic and quantum photonic applications.
