Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

阳离子絮凝剂PDA的合成与应用研究——对废纸再生造纸废水的处理(Ⅰ)
Gongye shui chuli, 2001 报道了用PDA处理废纸再生造纸废水的处理过程,研究了无机絮凝剂聚合氯化铝、聚合硫酸铁或有机絮凝剂PDA单独处理废水和无机絮凝剂与有机絮凝剂配合使用处理废水的效果。结果表明 :无机絮凝剂与有机絮凝剂配合使用有很好的处理效果 ;配合使用中有机絮凝剂相对分子质量较高者与阳离子度较高者相比,前者更有利于提高处理效果。对废纸再生造纸废水的处理使上清液COD去除率达74%～ 77%,透过率达92 %～ 99%,均超过作对比用的进口产品的处理效果,且下层絮体较大、坚韧、易于脱水。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Nickel‐based materials are highly remarkable as promising transition metal catalysts for the electrochemical hydrogen evolution reaction (HER) in alkaline electrolytes. However, their electrochemical performance is limited by an unfavorable d‐band energy (Ed) level. Herein, we showcase an effective lattice‐strain strategy to modulate the Ed of

Functional Ecology, Volume 40, Issue 6, Page 1921-1932, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Most terrestrial plant species form symbioses with arbuscular mycorrhizal fungi (AMF). However, the below‐ground carbon (C) allocation of plants and the nutritional and growth benefits provided by AMF within this symbiosis vary greatly across species and environments ...
