The recent discovery of superconductivity at a rather high temperature in the iron pnictides (Tc,max=56K) has revived some fundamental questions about the existence...

Carbonation and chloride ingress are the main causes of reinforced concrete degradation. A lot of studies describe these two phenomena separately but only few studies...

Magnetic frustration helps destabilizing conventional Néel order at T = 0 in dimensions 2, and therefore allows the emergence of new original quantum phases. The S=1/2...

Magnetic Resonance Imaging (MRI) has a high importance in medicine as it enables the observation of the organs inside the body without the use of radiative or invasive...

This work is a collection of my teaching activities and postdoctoral researches carried out within the laboratory "Chimie des Produits Naturels" (CPN) and the 'Natural...

Standard multidimensional NMR methods required to yield sufficient atom- resolution are time-consuming rendering real-time analysis difficult. The first part of this...

Catalysts are materials widely used in chemistry and particularly in the field of refining to convert heavy oil products in light products present in gasoline pool....

This thesis concerns the crystallization and the structural study of different alumino-silicate glasses. This study has led to several completely crystallized and...

The aim of the thesis is to improve the understanding of chemical equilibria involved in the actinides(III) and lanthanides(III) extraction in the DIAMEX-SANEX...

Beta-2-microglobulin is a 12kDa protein, involved in a misfolding disease: dialysis related amyloidosis. It is therefore a model for amyloid fibril formation and...

The PhD thesis was dedicated to the synthesis and bio-physic-chemical characterization of osmium nitrosyl complexes which could release nitric oxide (NO) in tumor...

Molecular recognition is one of the major challenges of supramolecular chemistry. Here, we present the design, synthesis and study of helical capsules properties...

The selection a small region within the body is a critical requirement for in vivo NMR spectroscopy. This thesis presents different methods to optimize this selection...

During this thesis, we studied the role of alkali elements and water on the structure and properties of aluminosilicates melts and glasses. Those compositions are...

This PhD investigation focuses on organometallic synthesis of indium phosphide (InP), zinc phosphide (Zn3P2) colloidal semiconductor nanoparticles (NPs) and core/shell...

Acrylonitrile is an intermediate of the chemical industry, used for synthesis ofnumerous polymers and coating. It is produced by ammoxidation of propene, which becomes...

To better understand the specifics of the flow of yield stress fluids in confined geometries, we opted for a multi-scale experimental and / or numerical approach in...

The aim of this study was to investigate the impact of the casein microstructure on the molecular diffusion of probes with different sizes and deformabilities. The...

Molten fluorides are used in Molten Salt Reactors MSR such as the non moderated fast reactor MSFR, where the molten salt LiF-ThF4 is the fuel and the coolant. The...

We propose multidimensional 1D and 2D NMR techniques for probing quantitatively the different saturations and dynamics of brine/crude oil/mud-filtrate mixtures...
