Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The design of nanoparticles confined in hollow N‐doped carbon structures is crucial for improving the oxygen reduction reaction (ORR) kinetics, yet achieving this remains a significant challenge. In this work, hollow porous nitrogen‐doped carbon encapsulated FeP/Fe2P (H‐FeP/Fe2P) were successfully constructed via a templating method combined ...

Gongye shui chuli, 2022 氮素负荷过高是淡水生态系统富营养化的直接原因之一。水体富营养化会导致藻类水华现象发生，消耗水体中的溶解氧，产生对人体有威胁的天然毒素，使水体不宜饮用、关键物种消失，最终导致淡水生态系统的退化。作为生物脱氮的前端处理阶段，短程硝化具有高效、低耗的性能而被人们广泛关注。对近年来短程硝化研究中的各影响因素，如微生物、温度、pH、游离氮、游离亚硝酸盐、DO、碳氮比、化学抑制剂等进行总结，同时综述了短程硝化耦合反硝化（PND）、短程硝化耦合厌氧氨氧化（PNA）及短程硝化耦合反硝化除磷（PN-DPR ...

Atomic‐scale understanding of interstitial‐strengthened high‐entropy alloys
Rare Metals, Volume 44, Issue 9, Page 6002-6014, September 2025.Graphic abstract Abstract Interstitial alloying has emerged as a powerful strategy to tune microstructure and microproperties of high‐entropy alloys (HEAs) due to the strong interaction of interstitials with constituent elements and crystal defects, which enables the development of advanced alloys with superior mechanical and functional properties.
