Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT To achieve high‐value utilization of spent catalysts, we recovered copper (Cu) from Cu‐bearing spent catalysts via acid‐base leaching to fabricate CuO and systematically studied how calcination temperature affects their microstructure and humidity‐sensing performance. Characterizations show that CuO‐500 (calcined at 500°C) has a large specific

, 2005 通过选取经济、社会、生态环境三方面24个与天山北坡经济带11个市县可持续发展密切相关的原始指标,通过因子分析对原始指标进行两级降维处理,最后得到3个综合指标。根据综合得分的数值对天山北坡经济带可持续发展能力进行排序,从高到低依次为:克拉玛依市、乌鲁木齐市、石河子市、乌苏市、奎屯市、米泉市、沙湾县、昌吉市、阜康市、玛纳斯县、呼图壁县。结合地域特征划分出3类可持续发展类型区:(1)综合经济实力型和工业经济主导型“强”可持续发展地区;(2)工业经济与农业经济均衡型“中”可持续发展地区;(3)农业经济主导型“弱”

, 2014 可持续发展是我们时代的主题,也是人类面临的最大挑战.自20世纪70年代,尤其是近20年来,可持续发展的概念日益频繁地出现在学术文章、政府文件以及公益宣传和商业广告之中.然而,为可持续发展提供理论基础和实践指导的科学——可持续性科学——是在21世纪初才开始形成的.该科学在短短的十几年中迅速开拓、不断发展,正在形成其科学概念框架和研究体系.中国是世界大国,是可持续性科学的哲学思想——"天人合一"——的故乡,有必要承担起时代之重任,在追求"中国梦"的同时促进全球可持续发展 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Spent automotive exhaust catalysts represent the largest secondary resource of palladium (Pd), and their efficient recovery is essential to support the sustainability of Pd‐related industries. Inspired by supramolecular chemistry, a novel calixarene derivative, 5,11,17,23‐tetra‐tert‐butyl‐25,27‐bis[(N′‐hydroxyacetimidamide)ethoxy]‐26,28 ...

Functionalized Silica‐Constructed Self‐Supporting Composite Separator for Lithium Metal Batteries
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Lithium metal batteries (LMBs) are considered highly promising next‐generation energy storage systems owing to their exceptionally high theoretical specific capacity and ultralow electrochemical potential. Nevertheless, the practical deployment of LMBs is still severely restricted by the uncontrollable formation and propagation of lithium ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Regulating oxygen vacancies (Ov) in SnO2 to facilitate high‐efficiency carbon dioxide electroreduction reduction reaction (CO2RR) is still a significant challenge. Therefore, a strategy based on Ag‐induced interfacial electron transfer was proposed to modulate Ov in SnO2 for CO2 electroreduction. The prepared Ag/SnO2 with an optimal Ov content
