Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Developing oxygen evolution reaction (OER) catalysts that combine high performance with cost‐effectiveness is a critical challenge for advancing the commercialization of anion exchange membrane water electrolysis (AEMWE). Practical application is often hindered by issues such as poor batch reproducibility and low‐cost efficiency.

Zhejiang Daxue xuebao. Lixue ban, 2002 用阴、阳离子表面活性剂改性制得一系列阴-阳离子有机膨润土,表征了有机膨润土的结构特征;研究了阴-阳离子有机膨润土吸附水中对硝基苯酚的性能及影响因素,探讨了其吸附机理,并定量描述了表面吸附和分配作用对总吸附的相对贡献率.结果表明,阴-阳离子表面活性剂在有机膨润土中形成了增溶(分配)作用较强的有机相,在一定配比下对水中的有机污染物产生协同去除效应;在高浓度时协同效应主要由分配作用所提供,在低浓度时由表面吸附所提供.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...
