如今纳米材料被越来越多地用于工业制造，但有些纳米材料贵比黄金，高昂的成本在一定程度上限制了纳米技术的应用。最近英国科学家开发出一种新方法，可有效地对纳米粒子材料进行回收并再利用。该成果发表于近期出版的美国化学学会《朗谬尔》（Langmuir）期刊。
纳米粒子很容易与其他物质混合，形成复杂的、难以分离的混合物，回收相当困难。而英国布里斯托大学的研究人员开发出一种特殊的微乳液（一种油水混合物），可...
日本将进行下一代输电网验证实验
日本 下一代输电网 验证实验
2010/4/26
日本经济产业省日前宣布，将于今年夏天在横滨等4地开始国内首次下一代输电网“智能电网”的验证实验，实验费用将达1000亿日元（1美元约合90日元）。
经济产业省官员说，智能电网利用信息技术，能瞬时掌握家庭和高层建筑的电力需求和发电方的供应能力，进行高效输电。在大规模发展易受天气影响的太阳能发电时，有必要通过智能电网技术来实现输电网的稳定。
