Gongye shui chuli, 2023 环境中重金属主要来源于工业废水的排放，如何经济有效地去除工业废水中的重金属是水处理领域的难点。重金属抗性菌比通常微生物具有更高的重金属抵抗能力，可以在重金属胁迫的情况下生长，这为重金属废水的微生物处理提供了新的思路。但是，目前人们对重金属抗性微生物的特性和应用仍然知之甚少。基于此，综述了重金属抗性菌的发现过程及其分离状况，对重金属抗性菌抗性能力的评价方法进行了介绍，着重分析了重金属抗性菌抗性机制中可作为去除重金属离子理论基础的胞外吸附与胞内累积机制，并以集成电路板生产关键工艺，即化学机械研磨（CMP ...

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐ion batteries (AZIBs) are expected to become one of the most promising candidates for large‐scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot‐peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)‐textured

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Heterogeneous structures have demonstrated great potential for overcoming the long‐standing strength–ductility trade‐off in metallic materials. In this study, a novel dual‐gradient structure, characterized by gradients in both grain size and precipitate distribution, was successfully constructed in an Mg–2Zn–0.8Gd (wt%) alloy sheet via sliding
