Reconfiguration of Localized Ruthenium Surface via Incorporating Single Platinum Atoms for Favorable Hydrogen Oxidation Catalysis

ABSTRACT Despite the fact that only 2% of active sites can satisfy hydrogen oxidation reaction (HOR) activity thanks to fast kinetics, the fuel cell anode is still dependent on catalysts with large amounts of platinum (Pt). Herein, a minimal‐cost ruthenium catalyst bearing ultral...

Uncertainty-Aware Adaptive Edge Blocking in Heterophilic Graph Neural Networks

Graph Neural Networks (GNNs) deliver strong performance through message passing (MP), yet they can become fragile when graphs contain many heterophilic links or when edge types are predicted incorrectly. Earlier analyses suggest that signed message propagation can reduce over-smo...
