Texto completoIn this thesis work, the purification efficiency of a filtration device, consisting of crushed sand and flax fiber geotextile layers, was investigated experimentally at the laboratory scale in order to install in local conditions (Havre agglomeration) an experimental site in full size. Two types of tests were used: (1) Batch tests to quantify the sorption potential of lead, copper and zinc ions by flax fiber tows from an aqueous solution , (2) Long-term filtration tests in laboratory columns filled with crushed sand with and without flax fiber geotextile layers to study the influence of the presence of geotextiles on the transfer and retention of (i) particles in unpolluted suspension (kaolinite particles) (ii) water-soluble heavy metals (iii) heavy metals in particulate form (metal ions adsorbed on suspended kaolinite particles) and heavy and water-soluble metals. Sorption tests have shown that the adsorption of metal ions by flax fibers is favorable with a maximum adsorption capacity of 9.9; 10.7 and 8.4 mg g-1 respectively for copper, lead and zinc. Filtration tests have shown that the presence of geotextiles in sand influences the transfer of heavy metals, in both soluble and particulate forms. The retention of metals in the sand is favored and the retention profiles are modified. In addition, and unlike synthetic geotextiles, flax fiber geotextiles themselves contribute to the retention of a significant fraction of metal pollutants in soluble and particulate form in their own structure. The overall metal retention efficiency of the filtration device is improved. These results are good indicators for considering the use of flax fiber materials in the design of local stormwater treatment systems and the removal of metal pollutants

Texto completoThis PhD takes place in the general context of possible solutions to global warming and peak oil issues. It mostly deals with the study and development of molecular electrocatalysts for carbon dioxide reduction. This process may open the way to the use and valorization of CO2 as a raw material. In the first part, a metallocavitand, which structure is based on a calix[4]arene modified by four phenanthroline tris-carbonyl rhenium(I) complexes, was studied in solution and deposited on a conductive transparent surface. The aim of this study was to control through an electrochemical stimulus the closing and opening of the wide rim of the cavitand. Complexity of the redox properties of the metallocavitand led us to investigate in detail the electrochemical properties of simpler examples of these rhenium(I) complexes. These properties were previously described in the literature ; however, there was disagreement in the interpretation of the results. Finally this study led us to a more precise and better understanding of the mechanism of the reduction of CO2 by a complex of this kind. In the second part, which is the main part of this PhD, synthesis, physico-chemical characterization and spectro-electrochemical study of bipyridine tris-carbonyl manganese complexes, analogues of the rhenium complexes mentioned above, were undertaken. The aim was to develop an innovative catalyst for the electrochemical reduction of carbon dioxide, based on a metallic complex, by substituting rare and noble metals currently used by a non-noble and abundant metal: manganese. Electrochemical properties of newly synthesized manganese complexes were investigated in detail. Simulations of cyclic voltammetry, associated with mechanism studies by UV-vis spectro-electrochemistry, allowed us to determine kinetic and thermodynamic properties of the different chemical reactions coupled with the irreversible electron transfers. These manganese complexes proved to electrocatalyse the reduction of carbon dioxide at least as efficiently as the analog rhenium complexes which were, until now, the best system for this application. These manganese electrocatalysts exhibit a very good selectivity (high faradic yields and no or very little H2) and a good efficiency for reduction of CO2 to CO in aqueous-organic media. Preparative scale electrolysis operates at low overpotential. Mechanisms of the different catalytic pathways were studied using UV-vis and EPR (continuous wave or pulsed) spectro-electrochemistry associated with DFT calculations. A key-intermediate was evinced and investigated. Finally the study of photo-induced decarbonylation reactions of these complexes is also described

Texto completoThe aim of this thesis is to investigate how material surfaces are affected by various surface treatments and how this relates to the adhesion of the coating. The materials that were studied were WC-Co and Cermets and the surface treatments used were polishing, grinding with coarser and finer abrasive grains, and finally wet blasting and dry blasting. Focus was on deformations and residual stresses in the surface, surface roughness and cracks. The test methods used for examining the samples included surface roughness measurements, residual stress measurements, adhesion tests using Rockwell indentation and SEM images of the surface and the cross section.
The results concluded that polishing gives very good adhesion. Additionally, the adhesion for ground surfaces was good for WC-Co but very poor for Cermets. Furthermore, it was observed that finer abrasive grains did not result in better adhesion. In fact, the coarser grains gave slightly better results. Finally, it was concluded that wet blasting has a clear advantage over dry blasting and results in much better adhesion, especially for the Cermets. The results for the WC-Co were a bit inconsistent and so further research is required.

Texto completoChemical Mechanical Polishing (CMP) consists in applying a slurry of colloidal particles onto a solid surface called substrate, through a pressure applied with a rotating polymeric pad. A silica substrate and CeO2 particles were chosen as reference system to study the mechanism of CMP. Macroscopic studies have shown the effect of the concentration and the size of abrasive particles, as well as the importance of pH and ionic strength. The mechanism was more thoroughly studied by recirculating the slurry in fixed conditions. Surface interactions between the substrate and the particles were studied thanks to a multi-instrumental approach (zeta potential, ATR-FTIR, TEM, SAXS, chemical analysis, AFM).A good understanding of the surfaces at stake is necessary to study the mechanism of polishing. Acid-basic and redox properties of the CeO2 surface were therefore investigated. Finally, the surface chemistry of the abrasive particles were modified (synthesis of core-shell particles and solid solutions), and different ceria morphologies were tested

Texto completoFor an idealized one-dimensional crystal it is possible to have energy levels whose wave functions are localized at the surface. These states are called surface states. There is one surface state for each energy gap between the ordinary allowed bands of energies. These electron states are called Tamm states. This Tamm state has an energy that lies almost at the middle of the energy gap and is mainly localized at the surface atomic layer. The image potential states are generated by a potential well formed by the Coulomb-like image potential barrier. These image states that are also called Shockley states are localized in a slowly decaying tail in the vacuum.
I also studied the lateral (in-plane) motion of electrons confined to terraces between steps on a vicinal Cu (111) surface. The local density of states showed a number of peaks at energies where electrons can occupy new quantum-well states on a step. I also tested the influence of the electron lifetime on the local density of states.

Texto completoTotally implantable venous-access ports are medical devices used for the administration of chemotherapy drugs and/or parenteral nutrition. Infections can occur and it is indispensable in modern-day medical practice to prevent and reduce the rare infectious complications. In this context, the goal of this work was to study the contribution of the modification of physico-chemical properties of titanium based surfaces on the adherence of microorganisms. Surfaces with different characteristics were produced and the adherence of the bacterium Staphylococcus aureus and the yeast Candida albicans was studied in vitro in static conditions. Model surfaces made of titanium dioxide with roughness from nanometer to micrometer were elaborated using silicon wafers recovered with a thin film of titanium dioxide deposited by plasma vapor deposition. Titanium alloy surfaces (Ti grade 2 and Ti grade 5) were modified by polishing, grit-blasting or wire erosion, to create different surface morphologies. In vitro studies were performed and it was found that the number of adhering microorganisms changed with roughness, but more importantly with the surface morphology of the biomaterials and microorganisms size. Flat titanium dioxide thin films were then functionalized by molecular grafting to modify the hydrophobicity of the surface. Study of plasma protein adsorption, by QCM, allowed to better explain the adherence of bacteria and yeast onto these surfaces. The influence of parenteral nutrition and chemotherapy drugs was also studied in order to better approach the real conditions of totally implantable venous-access ports

In this thesis, I created an algorithm to compensate for the saturation of data collected by the Mars Orbiter Laser Altimeter (MOLA). Saturation of the energy measurements had made it impossible to measure surface roughness at 100 m length scales. By calculating the returned energy, the problem of saturation can be avoided. This algorithm was applied to MOLA data across the Martian surface to create an estimate of surface roughness across the planet. The method calculates pulse spreading from returned pulse energy using the link equation. The accuracy of the method is limited by the accuracy of albedo measurements. This analysis improved the estimation of surface roughness on Mars. Further improvements could be gained by correcting for the opacity of atmospheric dust as a cause of pulse spreading.

Texto completoThe pattern of interannual variability of SST displays a dipole-like structure in the vicinity of the confluence of the two currents. That is, the SST fluctuations in both currents are roughly out-of-phase: warm episodes in one current accompany cold episodes in the other. It is suggested that the variability in the oceanic advection of the currents accounts for part of the observed variability in SST in the confluence region, the dipole pattern being associated with the strength of the temperature gradient in the confluence.
The pattern of variability of the air-sea heat exchange associated with the observed SST fluctuations displays a distribution of ocean-to-atmosphere flux anomalies roughly out-of-phase with those of SST. It is concluded that the SST fluctuations associated with the Brazil and Malvinas Currents are related to the variability in both the air-sea heat exchange and the oceanic advection of the currents.
The warm and cold events observed in the currents are associated with distinct atmospheric circulation patterns. Thus, it is suggested that changes in the atmospheric circulation on interannual timescales induce anomalies in the air-sea heat exchange, which have been found to be partly responsible for the variability in SST of the Brazil and Malvinas Currents.
