The TiO2 synthesized by normal and reverse micelles as templated were applied for phot ocatalytic of Rhodamine B and organic toxic small molecule 2.4-dichlorophenol under ultraviolet irradiation. Oxidation species and photodegradation products in the photoreaction process were detected for studying their photocatalyst properties. The results showed that: the R-TiO2 had a better photocatalysis property under UV irradiation when photodegradation of RhB and DCP compared to the N-TiO2. After 160min, the mineralized rate of RhB can be 95%. And the oxidative species was mainly referred to OH radical.

利用正相和反相胶束介质模板制备的纳米TiO2为光催化剂，在紫外光照射下，对染料罗丹明B和有机有毒无色小分子2，4-二氯苯酚进行光催化降解，研究了其光催化性能，并对光催化过程中氧化物种及降解产物进行了跟踪测定，结果表明，反相胶束模板体系制备的纳米TiO2与正相胶束介质制备的纳米TiO2比较，在紫外照射下对RhB及DCP的降解有较好的光催化性能，对RhB在160min尤催化矿化率可达95%，光催化反应主要的氧化物种涉及在基自由基。

The experimental results show that the aggregation morphology of P(AMC14AB) in aqueous solution is unimolecular micelle as expected.

在水溶液中，均聚物P(AMC14AB)呈现单分子链胶束的聚集形态，具有零临界胶束浓度，从开始加入P(AMC14AB)起，水溶液中随即产生单分子链胶束，不存在Krafft温度。

The results show that the decay of retinol and retinyl acetate are much faster in anionic micelles than that in cationic micelles and neutral micelles(TX-100), which indicate that the decay is carried out by the protonation of retinol or retinyl acetate first, then one molecular water or acetic acid is lost to produce the carbonium ion, which release the proton followed to generate the anhydroretinol.

数据显示，维生素A及其乙酸酯在阴离子胶束溶液SDS中的衰变速度要远大于在阳离子胶束溶液CTAB和中性胶束溶液TX-100中的衰变速度。

Moreover, the A-B-A triblock copolymer solution in a selective solvent, which is good for the block B, was explored. It was observed that the flowerlike micelles were formed, in which the central block B took on a loop conformation and the two end A blocks became a part of the micellar core. It was found that some of the soluble middle B blocks served as extended bridges between the small clusters by the poorly solvated end A blocks.

在A-B-A三嵌段共聚物溶液体系中，溶剂是链段B的良溶剂，是链段A的不良溶剂，此时我们得到了花型结构的胶束，其中花心是由链段A聚集而成，花瓣是由链段B形成的，而且在体系中也发现了有些胶束间存在着桥，并且在浓度很高时，体系出现了凝胶现象。

The effects of pH value and solvent on the micellar system were studied, and variation of their aggregates from spheres to connected rods was observed.

研究了溶剂和溶液pH值对胶束体系的影响，实现了从球形胶束到互相连接的棒状胶束的转变。

When the solution was heated to the temperature above the LCST, hydrogen-bonding interactions between the water molecules and the PEGMA segments on the surface of the micelles were destroyed and the multimolecular micelles joined together to form the even larger aggregates driven by the increasing intermicellar hydrophobic interaction.

通过UV-Vis和DLS研究发现，温度升至LCST时，胶束表面的亲水基团与水分子间的氢键作用被破坏，疏水基团相互作用加强，大胶束与大胶束缔合形成更大的聚集体，发生温度响应行为。

The antioxidative action may involve trapping the initiating radicals generated by AAPH in the bulk water phase, trapping the initiating radicals generated by DBHN in the surface of the micelles, inhibiting the propagating lipid peroxyl radicals on the surface of micelles and regenerating α-tocopherol by reducing the α-tocopheroxyl radical.

茶多酚的抗氧化机理可能涉及到在水相中捕获链引发自由基R00·和在胶束表面捕获链引发自由基t-BuO以及在胶束表面捕获链增长自由基LOO和在胶束表面与α-生育酚自由基反应从而再生α-生育酚。

The knowledge obtained here as well as the new morphologies identified provide useful information for future rational design and synthesis of novel multicompartment micelles.5. A superstrong segregation regime theory model for core-corona micelles and core-shell-corona micelles is developed.

这些信息对将来合理设计和合成新型多隔段胶束提供了指导。5、建立了用于描述核-冠胶束和核-壳-冠状胶束的超强分凝形式理论模型。

The micelle shape transformation of tert-octylpheny phenol polyethylene glycol ether (TX-100), sodium dodecyl benzene sulfonate and tetradecyl trimethyl ammonium bromide in heavy water solutions was studied by 1H nuclear magnetic resonance spectroscopy, including an NMR self-diffusion experiment. These experiments showed that the surfactants formed several shapes of micelles (spherical, ellipsoidal, and rodlike) at the respective concentrations which were far above their critical micelle concentration.

The separation is based on the differential migration of the micelle and the surrounding water and the differential distribution of the solute between the mi celle and aqueous phase,therefore,the separation mechanism is very similar to th at of micella electrokinetic chromatography.

这种分离方式是基于胶束和水相在色谱过程中的不同迁移以及溶质在胶束和水相间的不同分配而实现的，其分离的机制与胶束电动色谱(mic ellar electrokinetic chromatography，MEKC)十分相似。

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
