Повний текст джерелаElectrical and electronic equipment (EEE) has become an essential part of our daily lives. Much of the world's population enjoys a higher standard of living, thanks to their availability, widespread use, and easy access. However, the way we produce, consume, and treat waste electrical and electronic equipment (WEEE) is not sustainable in the long term. In Europe, despite having the most advanced waste legislation in the world, less than 50% of WEEE is properly collected and recycled. For several years, the company ENVIE2E du Nord, a subsidiary of the Vitamine T group, in partnership with l’Unité des Matériaux et Transformations (UMET), has been engaged in experimental work aimed at the recovery and reprocessing of certain WEEE. In this context, the general objective of this thesis focuses on the recovery of liquid crystals (LCs) as well as other valuable materials such as indium/tin oxide (ITO) and optical foils present in end-of-life liquid crystal displays (LCDs). An orderly, manual LCD dismantling line is in place at ENVIE 2E for differentiated recycling of electronic boards, cold cathode lamps that may contain mercury, polymers, metals, and other valuable materials. There is also an extraction line where LCD panels are opened and exposed to an ultrasonically activated organic solvent bath to recover LCs. The resulting solution contains the LCs, the solvent, and organic and inorganic impurities. The first part of this study consists in purifying and characterizing the LCs using chemical, thermal, optical, and dielectric techniques. A study on the influence of adding diamond nanoparticles to purified LCs was also performed. The second part consists in recovering indium from LCD panels. The extraction process is based on their size reduction and leaching. Finally, the characterization of the optical foils is carried out to know their composition and thus their recyclability

Повний текст джерелаUsing silicon as substrate for growing 3C-SiC monocrystalline material generates too many defects in the layers due to lattice and thermal expansion mismatch. Though these difficulties are avoided by using hexagonal SiC substrates, the random formation of 60° rotated domains in the 3C layers generate a high density of twins. The use of vapour phase epitaxy for the growth did not allow reducing significantly the twin density despite the optimization of the in situ surface preparation of the seeds. On the other hand, these defects were eliminated by using Vapor-Liquid-Solid mechanism which consists in feeding a Si-Ge melt with propane. The characterization of these twin-free layers showed excellent crystalline quality. Some of the impurities incorporated during growth (Ge, Al, B, Sn) were successfully analysed using accelerated ion beam techniques though the detection and quantification of these elements inside SiC thin films are challenging

Повний текст джерелаThis thesis aims at studying phenomena by which Ion Cyclotron Resonance Heating (ICRH) induces interactions between the plasma and the walls of tokamaks, the plasma-metal interactions being deleterious not only to prevent vessel materials degradation but also not to affect plasma performance due to the presence of heavy metallic impurity compared to foreseen fuel (namely deuterium and tritium). This problematic basically affects any machine aiming at heating the ions with waves at the ion cyclotron frequency, which in particular will be the case of ITER. This thesis is the result of a collaboration between CEA Cadarache (France) and the Institute of Plasma Physics in Hefei (China). Various experimental work have been carried out on the EAST (China) and WEST (France) tokamaks in order to identify the relevant parameters allowing to optimize the efficiency by which the ICRF waves – used to heat the plasma – must be excited in order to maximize the amount of power coupled, while simultaneously minimizing the plasma interactions with the walls due to this type of waves and the so called radiofrequency sheath excitation
