Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Lithium–sulfur (Li–S) batteries are promising for next‐generation high‐energy‐storage systems but are hindered by polysulfide shuttle, sluggish kinetics, and volume expansion. Conventional carbon hosts struggle to simultaneously anchor and convert polysulfides efficiently.

Revista Geografia, Literatura e Arte, 2018 A crise do conhecimento científico indica a necessidade de repensarmos o modelo uniforme de seu discurso na direção da abertura ao diálogo com outras linguagens e instâncias do saber humano, como a filosofia e, principalmente, as artes. Partindo desse pressuposto, faremos uso de alguns trechos do livro gráfico Do Inferno para analisarmos as ...

Shuitu Baochi Xuebao, 2011 为确定土壤铜、硫污染对苹果幼树生长发育的影响,以硫铁矿尾矿砂河滩垫地上栽植的苹果幼树为试材,研究土壤中的不同铜硫含量对苹果幼树生长发育的影响。结果表明:土壤中的铜含量≥46.8mg/kg,土壤有效硫含量≥368.7mg/kg时,苹果幼树的生长发育就会受到抑制;土壤中的铜含量≥53.9mg/kg,土壤有效硫含量≥538.0mg/kg时,苹果幼树受毒害甚至死亡。苹果幼树各器官铜含量的分布规律为:根系>叶片>新梢>1年生枝>2年生枝>主干,硫含量分布规律为:叶片>根系>新梢>1年生枝>2年生枝>主干 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Although alloy‐based materials present potential for peroxymonosulfate (PMS) activation, metal ion leaching remains severely restricted during the pollution degradation process. Herein, the porous carbon‐supported Fe–Cu alloy derived from industrial copper slag was prepared to remove the organic pollutants from wastewater while inhibiting the ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Lithium–sulfur batteries have attracted extensive interest owing to their exceptionally high theoretical energy density and environmental benignity. However, their practical performance remains severely constrained by intrinsic challenges, including the polysulfide shuttle effect and large volume expansion during cycling, which markedly ...
