Unveiling the Potential of Ba2Zn5As6 and Ba2Zn5Sb6: A Comprehensive DFT Study

open access: yesAdvanced Theory and Simulations, Volume 8, Issue 7, July 2025.
This study investigates the elastic, lattice dynamical, optical, and thermoelectric properties of Ba2Zn5X6 (X = As, Sb) compounds. Both materials are mechanically and dynamically stable. Electronic and optical analyses reveal indirect band gap ((Γ‐Y) and strong absorption in the visible region.

Defect‐Engineered Multi‐Intermetallic Heterostructures as Multisite Electrocatalysts for Efficient Water Splitting

open access: yesAdvanced Science, Volume 12, Issue 26, July 10, 2025.
A self‐supporting nanoporous multicomponent CoCuMoNi catalyst is synthesized. Through the synergistic effect of multiphase interfaces, built‐in electric fields, and defect engineering, the binding energy of key reaction intermediates in hydrogen evolution reaction (HER)/oxygen evolution reaction (OER) is modulated, achieving high activity and stability
