南极陨石 氮含量 地球大气
2015/3/1
德国研究人员在两块陨石样本中发现，其氮含量与人体和地球大气层中的氮含量很类似。发表于《自然地球科学》杂志中的该论文的三位作者分别来自拜罗伊特大学、得弗里德里希—希勒—耶拿大学以及马克斯普朗克研究员化学研究所，他们对两块1979年在南极洲发现的原始陨石分别作出具体分析，并提出了这些氮元素为何会存于陨石中的理论假设。
欧盟创新型自然解决方案加速海水油渍污染清除
欧盟 海水油渍污染清除
2015/3/3
鉴于海洋微生物的所向披靡无所不“吃”，因此海洋拥有巨大的自清洁能力，但自清洁需要花费一定的时间。世界海岸广泛分布的渡假圣地进入旅游旺季，沿岸海水的污染物清除，除利用传统的物理化学隔绝方法外，特别是浮在海水表面的泄漏油渍薄层的清除，因为需要花费太多时间，必须找到行之有效的快速解决方案。欧盟第七研发框架计划（FP7）提供900万欧元资助，总研发投入1250万欧元，由欧盟11个成员国及联系国希腊（总协调...
