Full textThis thesis is related on first hand to the technical study of a laboratory experimental set up, precursor of an innovative industrial ribbon growth process for photovoltaics, and on second hand to the scientific study of the segregation of impurities during the solidification of silicon under a strong electromagnetic stining. Numerica] and experimenta] studies, led in parallel, enabled to realize an experimenta] set up in our laboratory, without ribbon pulling. We managed the thennal control of the crystallization and we developed the system of electromagnetic retention. Those points were va]idated using mo]ten tin then liquid silicon. Various geometries of crucible were tested. We also validated experimentally the technical solutions related to the segregation of the impurities from a silicon feedstock ofknown composition in P, Fe, AI and Cu. Ingots and ]ayers of silicon were crystallized with high growth rates around 15 to 20cm/h, well above the usual crystal growth rates. The results of chemical analyses of samples showed that the turbulent flow resulting from the strong electromagnetic stining enable a coefficient of effective segregation k,rFO,54 for the phosphorus, one of the impurities which hardly segregates in silicon (ku=O,3) for a crystallization rate estimated to ]5cm/h. We developed three numerica] models to calculate the effective coefficient of segregation kefr in tUlbulent regime, in axially symmetric and in three-dimensiona] configurations. The values of kef! given by the models are locally close to our

Full textThe primary coolant of pressurised water reactors is permanently purified thanks to a device, composed of filters and the demineralizers furnished with ion exchange resins (IER), located in the chemical and volume control system (CVCS). The study of the retention mechanisms of the radiocontaminants by the IER implies, initially, to know the speciation of the primary coolant percolant through the demineralizers. Calculations of theoretical speciation of the primary coolant were carried out on the basis of known composition of the primary coolant and thanks to the use of an adapted chemical speciation code. A complementary study, dedicated to silver behaviour, considered badly extracted, suggests metallic aggregates existence generated by the radiolytic reduction of the Ag+ ions. An analysis of the purification curves of the elements Ni, Fe, Co, Cr, Mn, Sb and their principal radionuclides, relating to the cold shutdown of Fessenheim 1-cycle 20 and Tricastin 2-cycle 21, was carried out, in the light of a model based on the concept of a coupling well term–source term. Then, a thermodynamic modelling of ion exchange phenomena in column was established. The formation of the permutation front and the enrichment zones planned was validated by frontal analysis experiments of synthetic fluids (mixtures of Ni(B(OH)4)2, LiB(OH)4 and AgB(OH)4 in medium B(OH)3)), and of real fluid during the putting into service of the device mini-CVCS at the time of Tricastin 2 cold shutdown. New tools are thus proposed, opening the way with an optimised management of demineralizers and a more complete interpretation of the available experience feedback

Full textOrganic solar cells are low weight and particularly resistant to shocks (active layer and substrate in plastic). They are suitable for harsh environments such as military environment. Furthermore, conformability of these cells would permit to integrate them in mobile phones and other portable devices requiring high autonomies. The works of this thesis consisted to study different cell structures, improve reproducibility, realize cells with purified materials and make cells on flexible substrates in particular. The realization of cells on such substrates showed that the transition from a rigid substrate to a flexible substrate modifies only slightly the performance. The cells produced and characterized were mainly cells based on CuPc and C60. The deposition techniques used were spin coating and thermal vacuum sublimation. In addition, measurements of incident photon to current conversion efficiency (IPCE) showed that they depend on the incident light power. Other IPCE measurements permitted to estimate the phosphorescence time of C60 and determine the charge mobility in the CuPc. A radiometry study on the solar simulator was led in order to allow compare cell efficiencies with those of other laboratories. A method established permits to approach as close as possible the standard of illumination AM1. 5G with the simulator

Full textTrans-Golgi membranes and plasma membranes of eukaryotic cells are asymmetric, with their cytosolic leaflet enriched in aminophospholipids (APLs: phosphatidylserine and phosphatidylethanolamine). Dissipation of this asymmetry is involved in many (patho)physiological processes. P4 ATPases are prime candidates for APL transport and for maintaining asymmetry across membranes. In addition, yeast deleted for P4 ATPases display membrane trafficking defects. Besides, CDC50 proteins have been shown to interact physically with P4 type ATPases, and this interaction is important for addressing the complex to the right destination, and possibly also for its function. To gain insight into the molecular mechanism of lipid transport by P4 ATPases, the goal of my thesis was to develop the co-expression, in yeast, of a functional P4 ATPase, Drs2p, together with its partner, Cdc50p. The strategy we developed allowed us to obtain a membrane fraction enriched in Drs2p (~3%), mainly in complex with Cdc50p. Functional characterization of the complex identified phosphatidylinositol-4-phosphate (PI4P), a major regulator of membrane trafficking, as a crucial component for rapid completion of the Drs2p/Cdc50p catalytic cycle. We also purified the complex in one step on streptavidin beads. Finally, we started investigating the potential auto-inhibitory roles of the C-terminus (as the C-terminus of Drs2p contains a PI4P binding site) and the N-terminus of Drs2p, by expressing various truncated versions of Drs2p. Our work sets the stage for detailed functional and structural characterization of the Drs2p/Cdc50p complex and its role in membrane traffic

Full textThe objective of this study was to optimize the extraction of chitin by acid proteolysis. The novelty of the method is based on the stabilization of pH by the balance between substrate composition and the acid solvent. This principle allows a simultaneous demineralization and deproteinization, the two main reactions associated with the purification of chitin. To evaluate the performance of this purification, the composition of the substrate and products was characterized. Different methods of quantification of chitin and proteins have been compared. As traditional assays were not satisfaying, a direct method of amino acids determination by gaz chromatography was selected to estimate the amount of protein. The estimate of chitin amount was based on indirect methods, mainly gravimetry, elemental analysis and thermogravimetric analysis (TGA). Kinetics of demineralization and deproteinization were examined to optimize the purification of chitin. Mass balances confirmed the consistency of results. The quality of chitin extracted by enzymatic or chemical techniques was compared with the degree of acetylation and depolymerization and the crystallinity index of chitin. The structure of chitin was also observed by scanning electron microscopy (SEM). Finally, compounds solubilized by enzymatic hydrolysis were identified and quantified

Full textMalaria is a devastating disease caused by a parasite of the genus Plasmodium. Due to the spread of strains resistant to current antimalarial drugs, it is necessary to understand essential physiological functions of the parasite in order to find new drug targets. Membrane transport proteins are an important class of drug targets in humans, as they perform essential physiological roles of the cell. However, for Plasmodium parasites, just a few membrane transporters have been biochemically described. Recent gene-deletion studies in malaria mouse models have shown that the Plasmodium P4-ATPase, or lipid flippase, ATP2 is essential for the parasite. In eukaryotes, the phospholipid translocation activity of P4-ATPases is needed to maintain the asymmetric distribution of membranes, a key element in many essential processes like vesicle budding or apoptosis. Lipid flippases form heteromeric complexes with members of the Cdc50 protein family, also found in the genomes of Plasmodium parasites. To understand the functional role of these still putative transporters during malaria infection we need to study their transport mechanism and identify their substrate(s). We have conducted the heterologous expression in Saccharomyces cerevisiae of ATP2 in complex with the Cdc50 subunits from three different Plasmodium species. We succeeded to co-express the ATP2 ortholog of P. chabaudi (PcATP2) and the related putative PcCdc50 proteins. By co-immunoprecipitation and Fluorescence-detection Size Exclusion Chromatography, we have managed to identify the Cdc50 β-subunit that associates to PcATP2: PcCdc50.1. We then purified the complex PcATP2/PcCdc50.1 using immobilized nanobodies that recognize the GFP fused at the C-terminal end of PcATP2 and we initiated the functional characterization using ATPase and phosphorylation activity assays

Full textBy-products from wood industry, particularly knots, contain different types of molecules that can be valued as a source of bioactive components meeting therapeutic needs. It is on this idea that the project "Le Bois Santé" was designed. Through the collaboration of several partnerships, the present work aims initially to develop a "green" extraction processes (solid-liquid and supercritical) to obtain an extract rich in lignans from a mixture of norway spruce and silver fir knots. The effects of operating conditions on the extraction yield of each target compound and the antioxidant activity of the extracts were determined. To understand the entire process, the project aims to investigate the impact of concentration and drying processes using vacuum evaporation and lyophilisation. Moreover, the separation and purification of the compounds have been developed and optimized using frontal chromatography technique
