郑重声明，绝非机翻：由于在其表面缺乏隔热层和表面活性层的分解作用下，蒙脱土纳米颗粒被发现在聚丙烯中会失效。带有一个铵多聚磷酸基的钴的膨胀体现出一些由于改变了流变的协同作用。表层的作用和交叉改性在通过显微拉曼光谱和 x射线光电子能谱的分析后，在低表面能涂层围绕的纳米颗粒周围形成了一个抗热层，从而促进了它们在表层的迁移，且形成了一个富有弹性的阻挡层，从而表现出更好的性能。本人文科，物理化学知识有限，本文大多词汇都经过多次考证，如有差错，请多指教！

化学专业翻译2: Summarizing the experimental data available today， thiol-capped CdTe nanocrystals synthesized in aqueous solution represent a kind of stable highly luminescent core-shell QD system with a naturally sulfur-capped surface (CdS shell) created ... Summarizing the experimental data available today， thiol-capped CdTe nanocrystals synthesized in aqueous solution represent a kind of stable highly luminescent core-shell QD system with a naturally sulfur-capped surface (CdS shell) created by mercapto- groups covalently attached to the surface cadmium atoms. All chemicals used were of analytical grade or of the highestpurity available. Al2Te3 (lumps) used as a source of H2Te waspurchased from CERAC Inc.， WI. Milli-Q water (Millipore)was used as a solvent. UV-vis absorption spectra were recorded with a Cary 50 spectrophotometer (Varian). Photoluminescence (PL) measurements were performed at room temperature using a FluoroMax-2 spectrofluorimeter (Instruments SA). The room-temperature PL quantum efficiency (QE) of CdTe nanocrystals was estimated following the procedure of ref 41 by comparison with Rhodamine 6G (laser grade， Lambda Physik) in ethanol (Uvasol) assuming its PL QE as 95%.42 High-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray analysis (EDX) were performed on a Philips CM-300 microscope operating at 300 kV. TEM samples were prepared by dropping diluted solutions of transferred in toluene (by surface exchange of capping agent with 1-dodecanethiol) CdTe nanocrystals onto 400-mesh carbon-coated copper grids with the excessive solvent immediately evaporated. Powder X-ray diffraction (XRD) measurements were carried out with a Philips X¢Pert diffractometer (Cu KR-radiation， variable entrance slit， Bragg-Brentano geometry， secondary monochromator). Samples for this study were prepared by placing finely dispersed powders of CdTe nanocrystals on standard Si supports. To investigate the photostability of CdTe QDs， dilute colloidal solutions were irradiated for different time intervals with light of a 450 W xenon lamp cut around 400 nm by a band-pass filter having a bandwidth of _40 nm and a peak transmission of _40%. a “Stable” means here that colloidal solutions of CdTe QDs are stable for months and even years being stored under air in the dark at room temperature. “Moderate” means that colloidal solutions coagulate occasionally during the storage; however， they are generally stable for months as well. Independent of the stabilizer nature， CdTe QDs are generally stable (no oxidation， no or only very minor changes of the optical properties) for years in powder form and in closely packed or nanocrystal/polymer films being kept in the dark under air. b The charge of nanocrystals was evaluated from ú-potential measurements with employment of oppositely charged latex beads. The experimental conditions were chosen so that the ú-potential of the beads changed its sign after adsorption of a monolayer of nanoparticles. 展开

Syntheses and properties of fluorinated phosphate acrylates used for UV-curing coatings The acrylated perfluoroalkyl phosphates (PFPA I and PFPA II) used as an oligomer and monomer， respectively， for UV-curing systems were synthesized and characterized with 1H NMR and FTIR spectra. The photopolymerization behavior was investigated by using photo-DSC analysis， showing that both acrylates were photopolymerized quickly to a moderate final unsaturation conversion at the presence of a photoinitiator. The limiting oxygen indices of the UV-cured pure filmswere determined to be over 35. The surface properties of UV-cured polyurethane films added PFPAs， respectively， as additives were investigated by measuring the contact angles. The results showed that the addition of a small amount of PFPA I or PFPA II efficiently led to the increases in the contact angles， and the decreases in the surface tension. The X-ray photoelectron spectroscopy analysis confirmed that the film surface was enriched with fluorinated species. 展开
