胶束

Contrasted with the activity of the same reaction in oil-water double phased system, the hydrolyzing behavior of Camlicla Lipolytica Lipase in reversed micellar systems is much like that in oil-water double phased system. The stability and catalyzing activity are both enhanced and give rise to "superactivity". except in reverse micelles composed of cationic surfactant.

At first, the method of determined tannase activity was established, catalysis kinetics, catalysis characteristcs of tannase and solubility of it in RM were also studied. At the same time, various of factors effecting tannase activity were investigated.

本课题在单宁酶菌种选育及单宁酶制备研究的基础上，首次以反胶束体系为介质，确立了有机相中单宁酶活力测定方法，研究了单宁酶在反胶束中增溶定位方式、催化动力学和催化特性。

反胶束单宁酶的动力学性质研究 2.1 建立了HPLC同时测定反胶束酶催化体系中底物没食子酸和产物没食子酸烷基酯含量的方法。

The characteristic of BMS silica mesostructure and the effect of various synthesis factor (including ammonia/silica molar ratio, composition concentration variation, surfactant alkyl chain length, auxiliary organic molecules such as trimethylbenzene, catalyst structure and properties, solvent and cosolvent volume and its polarity, aging and drying conditions and postsynthesis hydrothermal treatment and so on) on the resultant BMS silica structure and properties were assessed using a series of analytical techniques such as XRD, SEM, TEM,〓Si MAS NMR, TG-DTA and N〓 adsorption measurements.

结果显示BMS二氧化硅分子筛是由大量封装胶束的纳米二氧化硅颗粒（约为20-40nm）堆积形成的聚集体，其双介孔分布中较小的介孔起因于颗粒内部表面活性剂模板形成的介孔，我们称之为骨架介孔。它类似于我们在MCM-41中看到的介孔，可通过改变表面活性剂胶束的尺寸而在2.56-3.65nm的范围内进行调节。

The steady state kinetics of the lignin peroxidase catalyzed oxidation of veratryl alcohol by H2O2 in a sodium bis(2-ethylhexyl) sulfosuccinate/isooctane/toluene/water reverse micellar medium was studied and a comparison with the corresponding aqueous medium was made to understand the effect of the reverse micellar medium on the catalytic mechanism and kinetic parameters.

为了理解木素过氧化物酶在反胶束介质中的催化性能与动力学行为，本文以LiP催化过氧化氢氧化藜芦醇反应为模型反应，研究了2-乙基己基琥珀酸磺酸钠/异辛烷/甲苯/水反胶束中上述模型反应的稳态动力学并与水介质做了比较。

After the click reaction of the SCL micelles and azide-terminus PNIPAM homopolymer, the novel PNIPAM-functionalized SCL micelles with pH-responsive cores and outer thermosensitive coronas were prepared, which was investigated act as excellent candidate of nanosized drug delivery vehicles.

另外，还可以使用溴丙炔对ATRP聚合出的PMEO_2MA-b-PDMA-b-PDEA三嵌段的中间PDMA嵌段进行部分季胺化，这样可以利用两端叠氮化的四甘醇来交联由PMEO_2MA-b-PDMA-b-PDEA在不同条件下形成的两种分别以PMEO_2MA或PDEA为核的胶束，从而实现了从同一个聚合物直接在水溶液中得到两种内核不同敏感的壳交联胶束。

In SDS-CaCl_2 system, the adsorption of Ca~(2+) ions on micellar surface can not result in the charge neutralization and there is no hydroxide group bridging effect in this system, so the surfaetant can not be flocculated in form of micelles.

在SDS-CaCl_2体系中，Ca~(2+)的吸附作用并未导致胶束表面电荷的中和，也不存在羟基架桥的作用，故该体系中的表面活性剂不能以胶束形式沉淀。

In SDS-FeCl_3 and SDS-PAC systems, no special chemical complexation reaction exists between the dominant species of metal ions and SDS, so no redissolufion phenomenon can be observed at high flocculant concentrations in these two systems. Secondly, when calcium or magnesium salt, which is very ubiquitous in natural water body, is added into surfactant micellar solution, surfactant can not be flocculated in micellar form.

但在SDS-FeCl_3及SDS-PAC体系中，金属离子主要存在物种与SDS间无特殊的化学络合作用存在，故这两个体系中在高混凝剂浓度下也观察不到沉淀重新溶解的现象。2向表面活性剂胶束溶液中加入天然水体中常见的钙盐或镁盐，表面活性剂不能以胶束形式被沉淀。

It can be assumed that, the Mg~(2+) ions remain as hydrated ion forms when adsorbed onto micellar surface because of its strong hydration effect, so it can not neutralize the micellar surface charge effectively, make it destabilized and flocculated, neither can it form low-solubility salt with SDS as in SDS-CaCl_2 system.

认为是由于Mg~(2+)离子的水合作用比较强，导致其以水合离子的形式在胶束表面吸附，未能有效地接近并中和胶束表面电荷，也未能像Ca~(2+)那样，与SDS形成难溶盐而结晶沉淀。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
