Abstract:

Les structures sandwich sont des structures légères composées de deux peaux superficielles minces, relativement denses, à haute résistance qui sont collées de part et d'autre d'une âme, épaisse, de faible densité telle que les mousses ou nids d'abeilles. Les matériaux sandwich à peau composite renforcée de fibres plastiques et à cœur en matériaux polymère représentent aujourd'hui une classe importante des matériaux structuraux légers dans de nombreux domaines de l'ingénierie tels que l'aéronautique et l'aérospatiale, l'automobile et les structures marines. Toutefois, certaines de ces structure

Abstract:

Nanoparticles are synthetic structures with dimension from 1 to 100 nanometers and are various in types. Some favorable properties peculiar to the nanoparticles (generally owing to size effects) make them prevailing and beneficial for applications in different scientific and engineering fields. A large portion of these properties find their connection to optics and photonics. In the context of optics, the thesis is devoted to study of two specific categories of nanoparticles, gold nanoparticles and CdSe-CdS core-shell quantum dots, aiming at investigating the influence and potential of the par

Abstract:

It is shown that the saturation of an aqueous solution containing K2PtCl4 with hydrogen in the presence of 6.3 nm silver nanoparticles leads to the reduction of platinum on the silver surface and the formation of Ag/Pt core-shell nanoparticles. The Ag:Pt molar ratio is varied from 9:1 to 1:9 for synthesizing Pt shell layer of different thickness. An apparent shift of Ag surface plasmon band from 405 nm to 230 nm and broadening of one with decrease of Ag:Pt ratio was observed. The TEM images and SAED pattern of Pt@Ag nanoparticles has been obtained. The UV-Vis and TEM data confirms a form

Abstract:

We discus methods for fabrication of silica and composite nanoparticles, which can be used in various biomedical applications. The most promising types of such nanostructures are hollow silica nanosheres, sil-ica coated plasmon-resonant nanoparticles (gold nanorods and gold-silver nanocages) and nanorattles. Mesoporous silica shell can be doped by desirable targeting molecules. Here we present the results of for-mation of nanocomposites composed of gold nanorods and double-layer silica shell. The secondary mesopo-rous silica shell is doped with a photosensitizer (hematoporphyrine in our case).

Abstract:

The vulcanization of rubber by sulfur is a large-scale industrial process that improves the mechanical properties of unsaturated rubber by the cross-linking of polymer chains. Microcrystalline ZnO particles are currently used as activator to enhance the efficiency of the crosslinking. Due to their not easy dispersion in the rubber matrix and to the relatively small fraction of ZnO which actually reacts with the other curative compounds, a large amount of oxide is required for the process. This leads to a not homogeneous vulcanization with inefficient polymer network structure and a possible re

However, particle size of nano-photocatalyst is usually too small to be separated and recycled from the reaction system, especially for wastewater treatment. These disadvantages lead to loss of photocatalyst particles and application of photocatalysis in scale-up is thus limited. The main objective of this research is to preparing magnetic TiO2 composite nanoparticles, which can be recycled by using external magnetic field. Magnetite nanoparticles were synthesized by chemical co-precipitation a

碩士<br>國立成功大學<br>化學工程學系<br>107<br>Abstract This thesis concerns the preparation and catalytic application of cobalt tungstate/cesium tungsten oxide (CoWO4/CsxWO3-H) composite nanoparticles, which could be synthesized successfully via two-step solvothermal process and the followed calcination in H2/Ar (5/95) atmosphere at 600oC. Because they possessed the excellent NIR photothermal conversion property of cesium tungsten oxide and the catalytic properties of cobalt tungstate, the resulting CoWO4/CsxWO3-H composite nanoparticles were utilized as the catalyst with near-infrared (NIR) and sunlight p

碩士<br>國立中興大學<br>化學系所<br>105<br>Protein phosphorylation is an important post-translational modification which plays a critical role in the regulation of many cellar processes, such as signal transduction, metabolic homeostasis, cell division and growth. Protein phosphorylation on tyrosine has emerged as a vital part in diagnosing and curing cancer due to commonly observed in tumor proteomics. However, the identification of tyrosine-phosphorylated protein remains a challenge due to poor ionization efficiency in mass spectrometer, ion suppression by non-phosphotyrosine peptides. Therefore, it is

Firstly, cesium tungsten oxide (CsWO3) nanoparticles were prepared by a wet-milling process and then coated with the silica shell with sol-gel method to yield the CsWO3@SiO2 nanoparticles. Next, their surface was amino-functionalized with 3-aminopropyl)triethoxysilane (APTES) to
