Defect‐Modulate Nanoalloy Catalysts Enable Efficient Catalytic Conversion in Lithium–Sulfur Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT To address critical issues in lithium–sulfur batteries, such as slow polysulfide conversion kinetics and shuttle effects, we designed and synthesized a high‐performance nanoalloy catalyst through a defect reconstruction strategy, aiming to enhance the electrochemical performance of batteries.

Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Dual‐Site Electronic Modulation in Mn/Fe‐Doped Ni0.85Se for High‐Efficiency Urea Oxidation at Industrial Current Density

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Rationally designing an electrocatalyst to achieve stable and efficient urea oxidation reaction (UOR) is crucial but still challenging, especially for ampere‐level application. Herein, Mn and Fe dual‐doped Ni0.85Se (Mn/Fe–Ni0.85Se) catalyst is synthesized via a facile and scalable electrodeposition and followed by selenization.

生物除铁除锰在钢铁废水回用处理中的应用

open access: yesGongye shui chuli, 2007
研究了锰砂过滤工艺在钢铁废水回用处理中除铁除锰的应用。在滤速5.0m/h、工作周期4d、反冲洗强度21 L/(m2.h)和反冲洗时间6 min的操作条件下, 经过自然生物培养成熟的锰砂滤层对钢铁回用废水中的总铁、锰的去除率达80%以上, 出水总铁和锰都达到再生水用作循环冷却用水的水质要求。同时成熟的锰砂滤料还具有一定的COD和氨氮去除能力。

Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

open access: yesJournal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

锰尾渣改良对4种植物吸收锰的影响

open access: yesShuitu Baochi Xuebao, 2007
采用盆栽法研究锰尾渣改良对商陆(Phytolacca acinosa)、美洲商陆(Phytolacca americana)、繁穗苋(Amaranthus paniculatus)和酸模叶蓼(Polygonum lapathif olium)4种植物吸收锰的影响。将锰尾渣与土壤混合进行基质改良,有利于植物生长。基质含80%锰尾渣时,商陆、美洲商陆和繁穗苋3种植物生长正常,吸收锰多。商陆和美洲商陆2种植物对锰尾渣耐受性强,生物量大,植物提取锰多;繁穗苋对锰尾渣耐受性较强。在锰尾渣污染区进行植物修复时 ...
