Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...
