Laser‐Generated CuPdAgPtAu High‐Entropy Alloy Nanoparticles—Thermal Segregation Threshold and Elemental Segregation

ABSTRACT In this study, noble metal HEA NPs (CuPdAgPtAu) are produced from equimolar and Cu‐ or Ag‐enriched bulk targets via laser ablation in liquids, with structural and compositional analyses by advanced electron microscopy and XRD, complemented by atomistic simulations. Equim...

High-throughput, picosecond laser interference-patterned doping of thin films for spatially resolved OER screening

Abstract The development of efficient oxygen evolution reaction (OER) catalysts requires a detailed understanding of how structural and compositional modifications influence the catalytic performance. Here, we present a high-throughput platform to induce structural and chemical m...
