By leveraging high-throughput data, we establish property-structure relationships across single-atom catalysts, alloys, and high-entropy materials. We analyze critical thermodynamic descriptors, including the $d$-band center and adsorption free energies ($\\Delta G_{H^}$ and $\\Delta G_{OOH^}$), to elucidate electronic interactions and active site synergies. Ultimately, this integrated approach enables rapid screening, providing robust guidelines for developing cost-effective, highly active electrocatalysts for scalable green hydrogen production.<\/p>\n<p><strong>Speaker:<\/strong><\/p>\n<p dir=\"ltr\">Juarez L.
