Aggregates of molecules do not grow into crystals of a size large enough to settle or be filtered out . 分子聚集体并不生长成为晶体,其粒子大小不足以使其沉降或被过滤出。
J - aggregates are specific supramolecular assemblies discovered by jelly and scheibe , which are characterized by a sharp , intensive absorption band with a bathochromic shift compared to a monomer band 20世纪30年代末期, jelly和scheibe发现一种特殊的超分子聚集体? j -聚集体,它具有尖锐且相对其单体红移的吸收带的独特光学特性。
Quantitatively describing the principle of protein - protein interactions and recognition in molecular level is the key point for understanding the relationship between structure and function of protein complexes and designing protein complexes , hi these interactions among proteins , electrostatic and hydrophobic interactions are the two most important ones , which let protein molecules bond systematically 在分子水平上定量地阐明蛋白质分子之间的亲合力和相互识别的机制,是正确地认识蛋白质聚集体结构和功能之间的关系并合理地设计出有用的蛋白质分子聚集体的关键。蛋白质分子间相互作用,其中最主要的是静电和疏水相互作用,使蛋白质分子能有序地结合在一起。
We are very interested in : a ) the relations among the molecular structures of amphiphiles , properties of molecular organized assemblies and phase behavior of mixed surfactants ; b ) the effective methods to adjust the phase behavior and micro - structure transition by the variation of environmental factors ( for example , ph , salt and additives ) 采用相应的实验和理论研究方法,了解多种类分子间作用力在有序结构分子聚集体形成过程中的作用机制及协同效应;寻求简便、有效的调控特定分子有序组合体的手段。
The main works are shown as the below : ( 1 ) . langmuir monolayer of behenic acid and dppc surfactants behenic acid is a classical amphiphile , it has been applied to prepare functional lb films and quantum semiconducting particle films . therefore , it is of essential importance to study behenic acid monolayer at the air / aqueous interface ; at additional , in the different subphase ( h2o cdcl2 ) conditions behaviors of behenic acid monolayers have been studied ; moreover , we study dppc monolayer at the aqueous subphase , stability of dppc at the different surface pressures and speed rates 研究内容如下: ( 1 )二十二酸、 dppc单分子膜成膜性能研究主要研究典型的小分子成膜化合物(二十二酸)在纯水和金属离子cd ~ ( 2 + )两种亚相下分子聚集过程,详细讨论了膜的形成和相变过程,分析了纯水和金属离子cd ~ ( 2 + )两种亚相情况对各状态下膜的静态弹性的影响;同时考查dppc单分子膜相变过程,同时研究了在不同压力处、不同压膜速度条件下对分子膜稳定性的影响。
