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 5, May 2026.ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT With the growing severity of volatile organic compounds (VOCs) pollution, metal‐organic frameworks (MOFs)‐derived materials offer a promising solution through efficient photothermal catalysis. In this paper, M‐MnOx (M = Cu, Ni, Co, Fe) catalysts derived from manganese‐based MOFs were successfully prepared by the sacrificial template method and

Preliminary exploration of heavy metal accumulation in Agaricus bisporus [PDF]
, 2016 随着工业化和城镇化的快速发展，越来越多的重金属污染物通过各种途径被释放到土壤等环境中。其不仅直接毒害土壤生物和植物，破坏生态结构，还可以通过食物链迁移转化，危害人体健康。究竟如何修复重金属污染是当前重要的环境问题。 本课题以人工培养的双孢蘑菇（Agaricusbisporus）AS2796为主要研究对象。对其以及杏鲍菇、茶树菇和秀珍菇菌丝体做不同浓度的重金属Pb、Cd和As胁迫处理，研究四种大型真菌重金属富集能力。检测结果表明双孢蘑菇较其他3个菌株而言，对Pb和Cd的富集能力更强。在1mg/L条件下 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Alkali metal–chalcogen batteries (AMCBs) are one of the most promising next‐generation energy storage systems because of their high energy density and reasonably low cost. However, the practical application of AMCBs is severely hindered by the volume expansion of the chalcogen cathode, the shuttle effect of polychalcogenides, and unstable ...

Shuitu Baochi Xuebao, 2004 土壤重金属的积累可促进地表径流中重金属的流失,流失量与土壤中重金属的形态有关。田间观测和室内模拟淋洗试验的结果都表明,径流或淋出液中重金属主要来源于土壤的交换态(包括水可溶态)重金属;土壤重金属总量与径流中重金属浓度相关不明显;用稀盐(0.01mol/LCaCl2)和1mol/LNH4OAc提取的土壤重金属量与径流和淋出液中重金属浓度都呈显著的相关,可较好地表征土壤中重金属流失潜力。

Research and application of heavy metal leaching of waste concretein Xiamen area [PDF]
, 2016 重金属是我国“十二五”规划中重点防控的污染物，重金属对环境和人体极具潜在的威胁，它不但不能被微生物分解，反而可以被生物体富集，或与某些阴离子（团）形成其他毒性更强的金属化合物。重金属在环境中将经历地质和生化双重循环迁移转化，并通过各种渠道（如大气、饮水、食物等）进入人体，这种摄取将对人体造成极大危害。重金属的过量能抑制生物酶的活性，影响人体正常的生物化学反应。重金属与人体蛋白质、核糖、激素等反应，形成金属络合物或螯合物，使其丧失或改变原来的生理化学功能而产生病变。 我国建筑产业飞速发展 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Piezocatalytic technology utilizes mechanical strain or stress‐induced piezoelectric phenomena to produce robust internal electric fields, markedly improving the separation efficiency of e−‐h+ pairs. This method has emerged as a focal point in catalysis by removing reliance on conventional light or electrical energy via its mechanical‐to ...

Shuitu Baochi Xuebao, 2007 为研究绿色无公害食品产地土壤重金属的含量与分布状况,以慈溪市周巷镇为研究区,利用综合指数法对土壤中重金属的含量进行评价,应用地统计学的方法分析土壤重金属含量的空间变化,并绘制土壤重金属的空间分布图。结果表明：以当地土壤重金属的自然背景为评价标准,所研究的8种重金属单项污染指数均大于1,说明8种重金属在该区均产生污染。以内梅罗指数法计算的土壤重金属综合污染指数为1.54,处于轻微污染的级别。研究区由北向南随地理位置和土地利用方式的不同,土壤中重金属含量有逐渐增高的趋势。不同剖面土壤重金属含量的研究表明 ...
