Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

SE PUBLICAR É PRECISO, AVALIAR TAMBÉM É! [PDF]
Revista de Administração de Empresas, 2018 O tema “revisão de artigos” é relevante e faz parte do cotidiano de todo pesquisador. Entretanto, a minha experiência como editor e revisor em periódicos brasileiros e internacionais torna evidente que o comprometimento dos pesquisadores na função de revisores, em geral, é muito menor do que quando estão na posição de autores.

Novos Estudos - CEBRAP, 2021 O objetivo deste artigo é argumentar que situações de privação material são inerentemente coercitivas. Para isso, avaliam-se teorias da justiça para as quais a pobreza não representaria uma forma de intervenção coercitiva em contextos de livre-mercado. Argumenta-se aqui que a pobreza precisa ser concebida como uma posição social subordinada e, portanto,

Shuitu 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 ...

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.

Gongye shui chuli, 2019 为了回收高锰酸钾废液中的锰，以高锰酸钾废液为研究对象，采用二硫代羧基化聚乙烯亚胺（DTPEI）作为锰回收剂，考察了强酸介质、pH、Mn（Ⅶ）初始浓度对DTPEI捕集锰的影响，并探寻了不同浸出液对锰的回收性能。结果表明，DTPEI在HCl、HNO3和H2SO4介质中对高锰酸钾溶液中的Mn（Ⅶ）均具有很好的捕集效果，最高捕集率接近100%。体系初始pH对DTPEI捕集锰的影响显著，pH为2.0~3.0时，锰的捕集效果较好，且随着体系pH的升高，达到较高捕集率所需DTPEI投加量明显减少；pH为4.0~6 ...

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.
