Texto completo da fonteIn the context of climate change, understanding the mechanisms by which vines adapt to the increasing frequency of heat waves is crucial for maintaining vine growth. Identifying key genes involved in the heat stress response is of paramount importance to promote grapevine adaptation and maintain grape quality. Such genes can also be used as molecular markers for breeding heat-tolerant varieties. Among these genes, transcription factors play a pivotal role in the regulation of heat stress responses, despite their incomplete characterization. The present thesis focuses on the involvement of VvCRF4, a transcription factor belonging to the AP2-ERF family, which is induced by high temperatures and plays a key role in grapevine thermotolerance. Using a transgenic approach in microvines, we demonstrated that VvCRF4 overexpression significantly improves thermotolerance. In addition, a combination of transcriptomic, cistromic and metabolomic approaches enabled the identification of genes and metabolic pathways associated with VvCRF4 activation under high temperatures. These findings contribute to a better understanding of the molecular mechanisms underlying grapevine's response to heat stress, and open up new prospects for developing more resilient grapevine varieties to face the challenges raised by climate change

Texto completo da fonteFor the application as a thermal barrier coating (TBC), the partially stabilized zirconia approaches some limits of performance which hardly can be overcome in the near future. Considerable effort is being invested, therefore, in identifying new materials with better performance than the current industry standard. Intuitive arguments based on crystallography and simulation may lead most rapidly to the development of new TBC materials. In this work, we have studied the physical properties of some ceramics that can be used in TBC system, such as : perovskite and pyrochlore compounds, zirconia and hafnia as well as zircon. The full-potential linearized augmented plane wave (FPLAPW) method is used to investigated the structural and electronic properties, giving more insight on the mechanical behaviour of these materials. The quasi-harmonic Debye model is applied to determine the thermal properties such as temperature dependence of bulk modulus, thermal expansion coefficient, specific heats at constant volume and pressure. Our results show mainly that lanthanum pyrohafnate is the best candidate for application as TBC

Texto completo da fonteA metal oxidation leads to a specific strain link to the oxide growth. This growth strain is supposed to be proportional to the oxide layer thickness. We study the " growth " stresses in some metals : nickel, untreated iron and phosphated iron. The first two materials oxidation is parabolic. On the other hand, the phosphated iron oxidation shows several features : phases inversion in the oxide layer, kinetic transition. Complementary analyses led by X – Rays Diffraction showed that the layer of phosphate seemed to play the role of a diffusion barrier. The stability of the phosphate layer during the oxidation and the oxide layers morphology confirmed that the kinetic accident has a mechanical origin. The measure of the stresses in the oxides has been achieved by XRD, with Synchrotron Radiation. In the first time, the stresses modelling in thermal oxides on metals allowed us to reproduce experimental results. Finally, we develop an identification method of the system parameters

Texto completo da fonteIn the glass making industry, for glass wool insulation production, cobalt or nickel based alloys are used. They operate at high temperature (HT) under specific conditions resulting from glass melts contact and burner proximity. When the T exceeds 1200°C, the properties of these alloys are lost. Increasing T can only be obtained by changing the alloys’ based material. In this frame, choosing chromium alloys is relevant because of the properties its oxide Cr2O3 confers. However, due to its high brittleness at low T and its ductility at HT, Cr has to be alloyed with other elements. In this work, the oxidation behavior of Cr at 1300°C was studied. Then 3 different systems were characterized. Towards the oxidation behavior only one is compatible with a HT environment. Its characterization then its optimization as well as the study of the phenomena met at HT (oxidation, corrosion, ageing, …) were then begun

Texto completo da fonteGlassy thin films are promising candidates as protective coating for high temperature applications. However, due to thermal and/or mechanical stresses under operating conditions, these materials may crack. Previous studies have shown that self-healing glasses in bulk form can be prepared by incorporating active particles. These latter, when damages occur in the material, oxidize at high temperature to form oxides that flow into the crack and form a “new” glass by reaction with surrounding matrix.Based on these results, our work aimed at transposing this concept to glass materials deposited as thin layers, and so to envisage coating applications. We have shown the feasibility of forming these innovative coatings composed of alternating vitreous and healing agent layers. They have been prepared by Pulsed Laser Deposition (PLD) and Electron Beam-Physical Vapor Deposition (EB-PVD). A first part of our work was devoted to the optimization of the deposition parameters and their influence on homogeneity, thickness and composition of thin films. The efficiency of the self-healing process of these composite materials was demonstrated in situ at 700°C by High Temperature Environmental Scanning Electronic Microscopy (HT-ESEM). Finally, we studied the behavior of these coatings when they were submitted to thermal cycles as well as the structural changes generated by their crystallization

Texto completo da fonteThe effects of microstructure on vortex pinning have been studied in the melt textured YBCO composite. TEM has been used in order to characterize the microstructural changes after postprocessing treatments. The different contributions to the critical current density have been separated and associated to a particular type of defect. In-plane dislocations have been found to contribute to weak pinning when the magnetic field is applied parallel to the c-axis. Y2BaCuO5 precipitates, twin boundaries and neutron irradiation induced defect cascades were found to contribute to strong pinning. Finally, the effects of adding Y2BaCuO5 and Ag2O inclusions on the microstructure features and critical current have been studied. In these two cases, an augmentation of the density of extended defects in the YBCO matrix was observed. These two types of materials allowed to quantify the effect of microcracks on the critical currents and to confirm the relevance of the model based on the partition of defect contributions
