Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization

open access: yesAdvanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Accelerated Discovery of Earth‐Abundant Oxygen Evolution Catalysts Through Surface‐Informed Active Learning

open access: yesAdvanced Science, EarlyView.
A surface‐informed active learning framework integrated with density functional theory enables resource efficient screening of the NiCoFe ternary composition space. Experimental validation identifies Ni55Co10Fe35 as the optimal composition, exhibiting favorable oxygen evolution reaction kinetics.
