简介：在海的油喷洒引起了许多世界范围的严重环境问题。在这研究，碳nanotube(CNT)海绵在海水上习惯于清除油slicks。这个方法与二传统的代表性的吸着剂相比，包括聚丙烯纤维织物和羊毛毡。CNT海绵比另外的二吸着剂有一个更大的油吸着能力。最大的油吸着能力(QCNT海绵的m)是92.30g/g，它比Q大12～13.5倍另外的二吸着剂的m(Q聚丙烯纤维织物和羊毛毡的m是7.45和6.74g/g，分别地)。另外CNT海绵不同于另外的二吸着剂，是superhydrophobic并且没在油喷洒清除期间吸附任何水。CNT海绵是潜在地为从海水清理油喷洒很有用。

简介：烟草种子油的丰满的酸作文表明油富于不饱和的丰满的酸，有罂酸的酸(71.63%)，油的酸(13.46%)和十六酸酸(8.72%)作为最丰富的不饱和、浸透的丰满的酸分别地。烟草油因此根据丰满的酸作文作为弄干半的类型被描绘。醇酸树脂树脂的合成被醇解执行或用碱的monoglyceride过程精制了烟草种子油，pentaerythritol，与锂氢氧化物一起的cis-1,2,3,6-tetrahydrophthalic酐是催化剂。那么准备的醇酸树脂树脂被发现是明亮并且有高注释的低颜色。弄干和坚硬性质和烟草种子油的粘附发源醇酸树脂树脂也一样的油长度的另外的醇酸树脂树脂被发现有点优异到那些。另外，水和说的醇酸树脂的酸抵抗也被发现可比较到另外的醇酸树脂。

简介：存在的油进口依赖指数不能确切测量经济费用或规模，并且描述油安全的节俭的方面是困难的。测量一国家经济的外国依赖并且反映它的油经济安全，这份报纸把网油进口紧张定义为进口花费了到GDP的网油的比率。由使用Divisia索引分解，在五个工业化国家和五个最新工业化的国家的网油进口紧张的变化在19712010期间被分解成五个因素：给价格，油紧张，油自足，国内价格水平和汇率上油。结果证明统治因素是油价格和油紧张；而且，最新工业化的国家让更高的网油比工业化国家进口紧张。
