胶束

These compounds, properly designed, can be 1～2 orders of magnitude more surface active than surfactants with a single corresponding hydrophobic and a single corresponding hydrophilic group in the molecules. In this work, selected trimeric surfactant TNP is first synthesized.

本文研究了Gemini表面活性剂GNP和GTB用于脂肪酸酯的碱性水解催化作用，测定了水解速率常数和反应活化能，从动力学机理上说明了所合成的Gemini表面活性剂对脂肪酸酯水解反应有明显的胶束催化作用。

Below its critical micelle concentration, SDS effect facilitated the energy transfer from the component at 232 nm to the tyrosyl residues in PS II proteins, and also resulted in less micropolarity for tyrosyl residues, whilst at or above its cmc, SDS had an opposite effect.

低于其临界胶束浓度时，SDS会促进蛋白质中232 nm外的组分与酪氨酸之间的能量传递，并且使酪氨酸残基外于极性更小的环境；而大于cmc时，SDS却产生相反的效应。

Also, CdWO4 nanowires and BaWO4 nanoparticless with different shapes, such as wire-like, rod-like, and hollow spherical, were prepared in different microemulsion systems using octane as oil, undecylenic acid and/or dodecylamine as surfactants.

此外，在十二胺、十一烯酸和正辛烷组成的反胶束乳状液体系中合成了不同形貌的BaWO4纳米粒子及丝状CdWO4纳米粒子。

The water content of the reverse micelles is a preferable parameter for charactering the properties of reverse micelles.

含水量是表征反胶束体系性质的一个较好的标志。

Novel shell cross-linked micelles with pH-responsive PDEA cores and thermo-sensitive PNIPAM coronas in aqueous solution were then fabricated by cross-linking the inner PDMA shells of the PDEA-core micelles.

通过BIEE对中间DMA嵌段的季胺化反应，可以得到结构固定的pH敏感的PDEA内核和温度敏感的PNIPAM外壳的壳交联胶束。

Novel shell cross-linked micelles with pH-responsive PDEA cores and thermo-sensitive PNIPAM coronas in aqueous solution were then fabricated by cross-linking the inner PDMA shells of the PDEA-core micelles.

在碱性条件下，该三嵌段聚合物自组装形成以PDEA为核、PDMA为内壳和PNIPAM为外壳的三层洋葱状胶束。

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束，由于中间亲水嵌段的作用，使PNIPAM的相转变温度提高，且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低，因此我们只能看到一个转变过程。2、通过原子转移自由基聚合，我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物，将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。

Then we studied the double phase transition behavior of three-layer nanostructures with double thermoresponsive shells. Successive RAFT polymerization of NIPAM and 2-ethyl methacrylate or DMA and NIPAM were conducted using PS macroRAFT agent. The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas.

另外我们还合成了含有PS、PNIPAM、PDMA三嵌段聚合物，也利用芘标记的方法可以得出：对于PS-b-PNIPAM-(来源：A29BC论文网www.abclunwen.com)b-PDMA胶束存在两个明显的相转变过程，第一个是内层的PNIPAM这一个很宽的温度(20-32℃)的塌缩过程，接着是32-50℃下的PNIPAM和PDMA的混合塌缩或聚集过程。

The simulations show that the distance between the two grafts plays an important role in control of the morphology.

模拟表明两个接枝之间的距离对胶束的形貌有重要影响。

If CSF is used as a sensitizing agent, its concentration should be lower than its critical micelle concentration.

从分析化学角度上看，若以阳离子表面活性剂作为BPR显色反应的增敏剂，则必须控制其浓度在其临界胶束浓度以下。

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
