Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

, 2012 以水稻、高粱和玉米为研究对象,考察了微囊藻毒素对受试作物的毒性差异,研究了不同浓度MC对萌发及萌发初期生长发育的影响,不同灌溉时期对受试作物生长发育的影响,检测指标包括发芽率、株高、鲜重、叶绿素、根系活力等。结果表明,受试作物对微囊藻毒素毒性并不一致,水稻发芽率受到明显抑制,高粱发芽率基本不受影响,玉米出现了低浓度促进、高浓度抑制的现象;MC对水滔、高粱和玉米的光合作用、株高和鲜重没有抑制作用,反而有一定的促进效果;不同灌溉时间条件下的研究结果表明,萌发前对高粱和玉米染毒会明显抑制植株根系活力 ...

, 2000 介绍了内分泌扰乱化学品 (EDCs)的作用机制及其对野生动物影响的研究进展。内分泌化学品可能与性激素受体、甲状腺素受体和其他受体 (如芳烃受体 )结合 ,也可能通过影响动物体内激素的代谢而对动物的生长发育起调控作用。各实验室的重复实验不支持环境雌激素之间存在协同作用的结论。已报道过的人体和野生动物生殖缺陷中具有充分证据的暴露 -效应关系的实例为数不多。尽管野生鱼类变性是英国河流中的一个普遍现象 ,但进一步的实验证明污水处理场出水中的天然和合成雌激素足以引起鱼类的变性反应 ...

Optimizing CuO on 3D Ordered Macroporous CeO2 for CO Oxidation in Rich Hydrogen
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT CO preferential oxidation (CO‐PROX) in rich H2 is considered a feasible strategy to solve CO poisoning for fuel cells, but obtaining good activity at low temperatures is still a challenge. Herein, three‐dimensional ordered macroporous (3DOM) CuO/CeO2 catalysts were fabricated by a templating approach, with the metal–support interaction (MSI ...
