Gongye shui chuli, 2023 自含锰土壤中筛选得到2株具有除锰能力的革兰氏阳性菌S1、S2，比对16S rRNA序列结果，推测2株细菌可能为巨大芽孢杆菌（Baciulls megaterium）和嗜麦芽寡养单胞菌（Stenotrophomonas maltophilia）。在质量浓度为260 mg/L的Mn2+培养基中培养6 d后，2株细菌对Mn2+的去除率均可达95%以上。扫描电镜能谱（SEM-EDS）分析、X射线衍射（XRD）分析表明这2株细菌是通过将Mn2+转化为MnCO3实现对Mn2+的去除 ...

Rare 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 ...

Rare 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.

Journal 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.
