In addition, the mechanism by which the growth proceeds is not very rigorously worked out. Due to the high dispersed capability of HY towards to Co(OH) 2 resulting in loose whisker-like microstructure of Co(OH) 2, small channels become available for the diffusion of OH - electrolyte ions through all Co(OH) 2 thin layer. Consequentially, the prepared composite shows a very high specific capacitance (483 F/g) and utilization (93%) of effective electroactive composition of composite.展开更多

文摘昆虫表皮蛋白(insectcuticular proteins,ICP)是结构蛋白,它和几丁质一起组成昆虫抵御外界环境的屏障——角质层。根据保守性基序的不同,ICP可分为CPR、CPF、CPFL、CPG和CPT5家族。它们都有独特的结构与性质。环境、激素、转录因子和内含子等共同影响昆虫表皮蛋白基因(insect cuticular protein genes,ICPG)的表达,进而使ICPG具有时期和组织特异性。ICP和ICPG被认为是研究昆虫蜕皮与变态的调控机理和理解昆虫发育期角质层在生物化学、物理化学以及结构上的修饰的重要模型,受到越来越多的重视。本文综述了ICP的分类以及环境、激素、转录因子和内含子等对ICPG表达的调控。
