俄美科学家 核污染水 廉价 净化技术
2017/6/20
俄罗斯喀山联邦大学与美国莱斯大学联合研发出核污染水的廉价净化技术，相关的研究成果刊登在美国《Carbon》科学杂志上。该工艺采用的原材料有两种：一种是被称之为“C-seal F”的碳材料，现主要作为石油开采业中钻井液添加剂来使用；第二种为自然界中的天然次石墨，两种材料均成本低廉。采用氧化剂对碳材料进行处理，提高其比表面积并在材料结构中添加氧元素，形成氧化改性碳材料。所获得改性碳材料可从核污染水中高...
A highly toxic water pollutant, known as perfluorooctanoic acid (PFOA), last year caused a number of U.S. communities to close their drinking water supplies. Because of its historical use in Teflon pr...

华东师范大学生态与环境科学学院夏建阳教授、美国俄克拉荷马大学骆亦其教授和阿拉斯加大学David McGuire教授课题组合作的研究评估了十个国际主流陆面模式对北半球冻土区碳循环的模拟情况。该研究发现，当前的全球碳循环模型对冻土区生态系统的净碳输入(即净初级生产力)的模拟存在巨大不确定性。
欧盟联合研究中心（JRC）近日公布了对多瑙河大区域空气污染的一项研究结果。结果显示，该区域主要城市的PM2.5污染来源中，住宅供暖占到35％，其次是农业（32％）、能源生产/工业（30％）和交通（25％）。为增强该区域空气污染治理的有效性，需要整合能源、交通等部门的政策和相关体制机制。
