Abstract:

This thesis presents the development of photonic tools towards the realisation of an optical intensity waveform synthesiser and of an attosecond pulse synthesiser based on the generation and Fourier synthesis of a continuous-wave coherent spectral comb spanning more than 3 octaves (UV to mid-IR) by use of a gas-filled hollow core photonic crystal fibre (HC-PCF).

The IL’s used in this study were either synthesized or commercially available. Preparation of the IL’s involved 2 step processes: firstly the heating of distilled 1-methylimidazole with distilled 1-chlorobutane under reflux to obtain 1-butyl-3- methylimidazolium chloride; secondly, the metathesis reaction of sodium tetrafluoroborate with 1-butyl-3-methylimidazolium chloride to obtain 1-butyl-3- methylimidazolium tetrafluoroborate. The addition of sodium tetrafluoroborate, sodium hexafluorophosphate and lithium trifluoromethane sulfonamide with 1-butyl-3-methylimidazolium chloride produced good

Abstract:

The aim of this thesis was to research the new synthesis methodology of ionothermal synthesis, used for the synthesis of zeolite type materials, mainly aluminophosphates. An ionic liquid or eutectic mixture is to act as both the organic template and the solvent, hence eliminating the space filling effects in the reaction from the water. Initial reactions were carried out using the ionic liquid 1-ethyl-3-methylimidazolium bromide which acted as the solvent and template in the production of four three-dimensional structures and one layered structure.

In this work, we deposited HA precursor films from weak basic electrolytic solution (pH= 8-9) via an electrochemical approach; the deposits were changed into crystallite coatings of hydroxyapatite by sintering at specific temperatures (600-800 ºC). The formed coatings were mainly characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). XRD patterns show well-defined peaks of HA when sintered under vacuum conditions. FTIR mea

Bioactive powders of silicon substituted hydroxyapatites containing 1.4-4.3 wt % Si were synthesized by precipitation from aqueous solutions of calcium nitrate and ammonium (sodium) hydrophospate.

Abstract:

The philosophy of green chemistry has seen much development in the past decade. The use of environmentally benign solvents is amongst the areas of green chemistry that have received the most attention. In this context, imidazolium ionic liquids have been widely reported to offer high product yields, fast reaction rates, excellent selectivity and generally mild working conditions, when used as reaction media. In addition, concerns about costs of solvents and the long-term environmental impact that can potentially result when solvents are discarded after their use have led to focused investigati

Abstract:

Cerium dioxide is a unique material which is promising for biomedical applications. The properties of ceria are definitely determined by synthesis procedure and further treatment conditions. The vast majority of currently existing methods of synthesis lead to formation of CeO2 in the form of nanopowders, but in some cases (e.g., in biological applications), such powders can not be used because they do not quite satisfy practical requirements. So, in this work we succeed in synthesis of ceria-stable sols with controlled small particle size (2-4 nm) using an inexpensive and facile method an

Abstract:

The main objective of this research work was the development, synthesis, and study of polymeric chelating derivatives. These derivatives were characterized in terms of their specific metal affinity interaction with biomolecules and metal ions. These engineered materials were used to test their feasibility as tools for separation of proteins and heavy metal ions from aqueous solutions using different affinity separation techniques. Linear and branched polymers were synthesized to create a variety of materials. Among the linear polymers synthesized was the chelated monomethoxy poly(ethylene) gly

Les nanotubes de carbone (NTC), très petits, creux et monodimensionnels, sont très étudiés du fait de leurs excellentes propriétés thermiques, électriques et mécaniques. Les buts de cette thèse étaient premièrement de préparer des poudres et mousses de solutions solides Fe/Al2O3 et des poudres Fe/Al6Si2O13, servant comme matériaux catalytiques pour la synthèse de nanocomposites NTC-Fe-oxyde, et deuxièmement de faire une étude approfondie de tous ces matériaux par spectroscopie Mössbauer du 57Fe et de corréler les résultats avec ceux issus d'autres techniques, de manière à obtenir des informati

Abstract:

Cette thèse étudie différents problèmes de minimisations avec des fonctions de régularisations qui promeuvent la parcimonie. Plus précisément, on souhaite reconstruire une image, que l'on suppose parcimonieuse et qui a subit une transformation après un opérateur linéaire, à l'aide de problèmes de minimisations. Dans ce manuscrit, on s'intéressera plus particulièrement à la minimisation l1 synthèse, analyse et bloc qui sont très utilisées pour reconstruction une image que l'on sait parcimonieuse. Ces minimisations produisent en pratique des résultats convaincants qui n'ont été compris théorique

Abstract:

The three major biopolymers, proteins, nucleic acids and glycoconjugates are mainly responsible for the information transfer, which is a fundamental process of life. The biological importance of proteins and nucleic acids are well explored and oligosaccharides in the form of glycoconjugates have gained importance recently. The β-(1→4) linked N-acetylglucosamine (GlcNAc) moiety is a frequently occurring structural unit in various naturally and biologically important oligosaccharides and related conjugates. Chitin which is the most abundant polymer of GlcNAc is widely distributed in nature where

Abstract:

Des cristaux de Ga1-xFexPO4 ont été obtenus par voie hydrothermale avec xmax=0.23. La synthèse hydrothermale in-situ par spectroscopie d'absorption des rayons X a permis de mettre en évidence le rôle essentiel des cations Ga3+ lors de la nucléation et la cristallisation de la phase mixte Ga1-xFexPO4 de structure quartz-α. La solution solide a été particulièrement étudiée par spectroscopie Raman et des calculs théoriques par DFT ont permis d'identifier clairement les modes de vibration dont la fréquence dépend de la composition chimique du matériau (modes couplés).
