Abstract:

Chemical composition distribution (CCD) of copolymers describes the distribution of average comonomer content among copolymer chains. This information is very important as CCD can significantly influence physical properties of copolymers. The main goal of this study is to further our understanding of the CCD of copolymers.<br>The present understanding of CCD of multicomponent copolymers is very limited and there are no analytical equations capable of describing this distribution. In the present study, analytical expressions for describing the CCDs of random multicomponent copolymers are

Abstract:

Zeolites are crystalline, hydrated aluminosilicate minerals that are characterized by their ability to exchange some of their constituent cations with cations in aqueous solutions, without a major change in their crystalline structure. Clinoptilolite is the most abundant ype of zeolite and it has received extensive attention due to its favorable selectivity for mmonium and certain heavy metal cations. The aim of this study is to investigate the binary and ternary (multicomponent) ion xchange behavior of sodium form of G&ouml<br>rdes type clinoptilolite for ammonium,cadmium and sodium ions. For

Cette thèse traite des systèmes de Hall quantiques en deux dimensions, dans lesquels les électrons peuvent porter plusieurs degrés de liberté discrets différents. Le ferromagnétisme de Hall quantique fournit une manière de traiter ces degrés de liberté électroniques comme des spins et isospins effectifs des électrons. Les différentes phases du système correspondent alors à différents ordres de spin ou d'isospin. En exploitant cette analogie, nous explorons différents aspects des systèmes bi-dimensionnels dans le régime de Hall quantique en étudiant la structure correspondante des spins et isos

In this study binary and ternary ion exchange on Zeolite NaA using silver and cadmium ions were investigated. Ion exchange were conducted at constant temperature (25oC) and normality (0.1N) in a batch system for both binary and ternary experiments. Zeolite weights were varied between 0.1 and 1 g for binary experiments. Thermodynamic analysis of binary ion exchange between Cd2+-Na+ and Ag+-Na+ were examined and thermodynamic equilibrium constant and Gibbs free energy were calculated. Thermodynamic equilibrium constants were found as respectively 28.2 and 300.4 for Cd2+-Na+ and Ag+-Na+ binary s

Abstract:

This thesis is a theoretical study of configurational and magnetic interactions in multicomponent solids. These interactions are the projections onto the configurational and magnetic degrees of freedom of the underlying electronic quantum mechanical system, and can be used to model, explain and predict the properties of materials. For example, the interactions govern temperature induced configurational and magnetic order-disorder transitions in Heusler alloys and ternary nitrides. In particular three perspectives are studied. The first is how the interactions can be derived from first-principl

Multicomponent polymer systems comprised of two or more chemically different polymer moieties provide an effective way to attain the desired properties from a limited palette of commodity polymers. Variations in macromolecular topologies often result in unique and unusual properties leading to novel applications.

Blends of cyclic and linear polymers were compared to their topological counterparts, polyrotaxanes, in which cyclic components are threaded onto the line

Nuclear and gas turbine power plants, computer chips, and other devices and industries are running hotter than ever for longer than ever.

The diffuse-interface method known as the phase-field model is a useful tool in the simulation and prediction of thermotransport driven microstructure evolution in materials.

The synthesis algorithm employs a depth-first tree search in order to locate solutions and unit design variable discretisation to reduce the search space. The algorithm generates a set of good, feasible solutions which may be further optimised by continuous means. The method is applied to two different types of problems.

Four different receiver structures are considered: (i) the standard delay-and-multiply form, which is optimal when only the shot noise is present but is severely degraded by quite small amounts of phase noise; (ii) the matched receiver, which tolerat

Abstract:

X-ray Emission from Low Mass Binary Systems X-ray time-series and spectra of two LMXRBs are presented. The data are from the the well-known X-ray burster MXB1636-536 and the dipping source 4U1624-49. In the case of MXB1636-536, a simultaneous optical observation is also presented. The 2-20 keV persistent X-ray emission from MXB1636-536 is found to show both positive and negative hardness-flux correlations and to vary by a factor of &sim; 2 on timescales of hours. The persistent spectrum is best described by a power law with high energy cut-off, indicative that Comptonization dominates the spec

Abstract:

Le futur observatoire spatial d’ondes gravitationnelles LISA ouvrira une nouvelle fenêtre pour la mesure des ondes gravitationnelles, permettant d’observer des sources difficilement visibles avec les observatoires terrestres actuels. Parmi ces sources, la détection des binaires galactiques promet une richesse d’informations sans précédent, mais soulève également plusieurs défis d’analyse de données. En particulier, le grand nombre de sources attendues et la présence à la fois de bruit et d’artefacts entachant les données nécessitent le développement de méthodes d’analyse robustes.Grâce à une m
