摘要: 通过改进Stober方法,严格控制反应条件合成了平均直径为238 nm、分布偏差约为5.7%的球形二氧化硅单分散颗粒. 首次利用乙醇作为沉降介质,在重力场作用下制备了二氧化硅光子晶体. 提出了自组装方法生长光子晶体的机理,并对缺陷形成原因进行了初步分析.
关键词: 光子晶体, 单分散, 二氧化硅, 生长机理, 缺陷
Abstract: A strain Pseudomonas sp. ZJU-02 was screened from 7 strains. The strain had high lipase producing ability proved by the Rodamine B plate method. The results in shake flask cultivation showed that the suitable lipase producing media were: corn steep 3%, vegetable oil 1%, K2HPO4 0.1%, KCl 0.05%, MgSO4 0.05%, Tween 80 0.05%. Under optimal culture conditions (26oC and pH 6.5), the maximal lipase activity could reach 86 IU/ml. This enzyme was stable under 70oC and pH 7~10.5. The optimal conditions for the enzymatic reaction were 40oC and pH 9.5. This enzyme showed a good potential application in detergent and tan industry.
Key words: photonic crystal, monodispersed, silica, growth mechanism, defect
