Abstract:

Specifically binding ions induce the transition of anionic polyacrylate coils from extended conformation to collapsed globules passing through a cascade of intermediate states when solution conditions approach the L-type precipitation threshold. It is the conformation of these intermediate states on surfaces and in solution which is at the focus of this thesis. In comparing the surface and solution conformations of intermediate states, we were able to qualitatively and quantitatively underline the effects of sample history. Two types of quantitative comparisons have been emphasized. In r

Abstract:

Nesse trabalho, são investigadas as propriedades dinâmicas de modelos da mecânica estatística na criticalidade. Inicialmente, trabalhando com modelos de spin e utilizando os conceitos de persistência global e de dimensão anômala da magnetização inicial, mostramos que o modelo de Baxter-Wu não está na mesma classe de universalidade dos modelos de Potts com quatro estados e de Ising com interação de três spins em uma direção, todos bidimensionais. Na segunda parte da tese, estudamos o fenômeno de crescimento da superfície gerada pela deposição segundo as regras que definem os autômatos celulares

Abstract:

Mechanics and biological function of nucleic acids are intimately coupled. The DNA double helix must be opened to allow base pairing of RNA during transcription; RNA must bend and fold in its many cellular functions. Presented in this dissertation are two investigations of mechanical deformations of nucleic acids, conducted with optical tweezers.In the introduction, the mechanical properties of DNA and RNA and their relevance to their cellular functions are introduced, to give the reader context for the results presented in the Chapters 2 and 3. This is followed by an introduction to the theor

Abstract:

L'apparition ces dernières années de supraconducteurs réalisés industriellement utilisant des composés à haute température de transition offre la possibilité de nouveaux développements en magnétisme supraconducteur. En effet ils permettent d'augmenter le champ magnétique généré en conservant une cryogénie classique à 4,2K d'une part, et ils ouvrent la voie à des développements d'aimants supraconducteurs fonctionnant entre 10 et 30K d'autre part. Les matériaux supraconducteurs à haute température critique sont alors indispensables pour dépasser les inductions magnétiques de 16 T (cas de l'inser

Abstract:

碩士<br>國立成功大學<br>化學工程學系碩博士班<br>100<br>This thesis is to explore the use of particle-tracking microrheology techniques in studying the coil-globule transition of single molecule polymer. This approach is validated by comparing the measured results with predictions by the classical Flory-deGennes theory and those using the Ostwald viscometer (Chapter 3). As a complementary study, small angle X-ray scattering (SAXS) is also employed to probe the microstructures of a polymer chain (Chapter 4). In Chapter 3 we measure how the viscosity of a dilute poly-2-vinylpyridine (P2VP) solution changes with pH

Abstract:

Several analytical mean field models are presented for the class of stimuli responsive polymers that are driven by the lower critical solution temperature (LCST) transition. For solutions above the polymer crossover concentration, a hybrid model combines lattice-fluid excluded volume and van-der-Waals interactions with a combinatorial approach for the statistics of hydrogen bonding, hydration, and ionic bonding. This approach yields models for the LCST of both neutral polymers and lightly charged polyelectrolytes in aqueous salt solution. The results are shown to be in semi-quantitative agreem

We also investigated some statistic properties (e.g., End- to- End Distance, Radius of Gyration). The results show that bond bending force is not only a promising strategy to control the angle between the bonds, but also made a great impact on polymer morphology

These X-shaped molecules consist of a rod-like core, with a polar group at each end and two lateral chains. The influences of changing the two lateral chains relative miscibility, lateral chains length and solvent concentration in solution on the morphologies are discussed. The results show that changing the two lateral chains length and the solvent concentration can effectively control the morphologies. And the h

Poly-norbornene based homopolymer derived from ring-opening metathesis polymerization (ROMP) is regarded as rigid backbones because of the bicyclic constraints of norbornene. Decrease of backbone rigidity can be achieved through the alternating copolymerization of an appropriate cyclic olefin comon

Abstract:

The development of solution-processable semiconducting polymers has brought mankind’s long-sought dream of plastic electronics to fruition. Their potential in the manufacturing of lightweight, flexible yet robust, and biocompatible electronics has spurred their use in organic transistors, photovoltaics, electrochromic devices, batteries, and sensors for wearable electronics. Yet, despite the successful engineering of semiconducting polymers, we do not fully understand their molecular behavior and how it influences their doping (oxidation/reduction) properties. This is especially true for donor
