Bruneau, Marion. "Elaboration de matériaux composites hybrides pour l'encapsulation de molécules d'intérêt relargables sous différents stimuli." Thesis, Mulhouse, 2020. http://www.theses.fr/2020MULH3696.
Повний текст джерелаThis work is devoted to the development of materials allowing the controlled release of molecules of interest. In the first part of this project, syntheses of organic-inorganic hybrids having a talc type structure were carried out with different silica sources, which induces variable crystallinity and polycondensation of silicic species. These hybrids were then characterized. The folic acid (molecule of interest) once added to the synthesis medium was encapsulated into the hybrid. The incorporation of folic acid does not induce significant changes in the structure of the hybrids formed. The different characterization techniques have shown that the folic acid is not very mobile in the structure and is therefore well encapsulated in the interlayer space of the hybrids. The hybrids showed a fast releasing kinetics, both in water or in a model soil. Hybrids prepared from N2TMS (N- [3-(trimethoxysilyl))propyl]ethylenediamine) showed the fastest release, while those synthesized with C16TMS (Hexadecyltrimethoxysilane) exhibited the slowest releasing kinetics due to the highly hydrophobic nature of the organic chain of the hybrid. The second part of the thesis was focused on finding and testing materials potentially active in the photo-controlled release of active molecules. The hybrid materials synthesized from NBATES (3-(triethoxysilylpropyl)-4- nitrobenzamide) have shown promising results: under UV irradiation at 254 nm, the quantity released of a model molecule was indeed two times higher than that measured in the absence of light. For the hybrids synthesized from MCTES (O-4-methylcoumarinyl-N-[3- (triethoxysilyl)propyl]carbamate), the best results was obtained under UV irradiation at 365 nm. The photosensitive functional groups present in the talc type hybrids made possible to obtain photosensitive composites. These promising results are the base for further developments in agricultural applications

Повний текст джерелаThis thesis describes the synthesis and study of organic-inorganic talc like hybrid. The synthesis is inspired frome the work of Fukushima & Tani in 1995. This synthesis is particularly attractive because of soft conditions. Thus this work describes the search for optimum conditions of synthesis on the example N- phenylaminomethyl - TLH. Subsequently, we describe the synthesis of a wide range of organic-inorganic talc like hybrid. Many characterization techniques are then used to precisely describe the structure of these materials. The last chapter illustrates the application as a reinforcement of these hybrid materials

Повний текст джерелаThe aim of this PhD work was to synthesize and test new nano-objects for the diagnosis and treatment of cancer. For this purpose, we developed hybrid nanoparticles made of an inorganic core surrounded by a human serum albumin (HSA) organic coating. The inorganic core is a composite by itself as it is made of an iron oxide core (IO) surrounded by a mesoporous silica (MS) shell. The IO core ensures, through its magnetic properties, diagnosis by magnetic resonance imaging (MRI) and therapy by magnetic hyperthermia, whereas the MS shell allows the loading of anticancer drugs for chemotherapy within its porosities. The pore sizes of the silica shell were modulated to enhance the drug loading content and the IO core size was also tuned to improve magnetic hyperthermia as well as T2 MRI imaging properties of the final core-shell system. The use of a thick shell of HSA as gatekeeper for controlled drug delivery triggered by its degradation with proteases was also studied. In parallel the synthesis of drug loaded HSA nanocapsules using MS as sacrificial template was performed. Finally, the biological activities of these nanoparticles were tested on various cancer cell lines

Повний текст джерелаIn most real shop floor, improving the coordination and the planning of the production with respect to the logistic activities, namely resources : machines and material handling equipments, became a great necessity for the lowering of costs and reducing of lead-times delivery. The present thesis is split into four parts. The first one is a survey of the scheduling problems ; the emphasis is on the Job Shop environments. In the second part, we provide a more detailed study of these environments : problematic, state of the art, modelling and methods of resolution. As part of the internal logistics of the production facilities in Job Shop Scheduling Problem, the third part is devoted to showing two problems, the Job Shop Scheduling Problem with transportationfor just-in-time production as well as the flexible Job Shop Scheduling problem with machines availability constraints. Finally, the last part addresses the aircraft landing problem that we formulated as a Job Shop problem. In the various study cases previously cited, our work revolves around a systematic study based on three fundamental processes, a mathematical and/or graphical formulations, and then an approach for resolution optimization based on hybrid metaheuristics, finally a validation of the results by numerical simulations. The objective is to develop dynamic scheduling systems to resolve these NP-hard problems

Повний текст джерелаThe increase of world energy production involves the research and development of new more efficient and ecofriendly processes for uranium ores valorization. Therefore, the development of new materials for an efficient solid-liquid extraction of U is necessary. In this thesis, the synthesis of materials named Metal Organic Framework (MOF) and their use to the uranium extraction from ores are studied. MOFs are hybrid and crystalline materials showing high performances for uranium extractions in weak acid solutions.In order to answer to this objective, the stability of two type of MOFs has been studied at different contact time in acidic solution simulating the ore leachate. Afterwards, zirconium based MOFs functionalized with two different organic functions have been synthesized and characterized with PXRD, BET, TGA, SEM, FT-IR and NMR. The uranium extraction behavior with three functionalized MOFs has been studied in function of the contact time, uranium concentration, sulfate concentration and pH. The uranium extraction values coupled with spectroscopic analysis of uranium loaded materials afford the understanding of uranium extraction mechanisms for both materials.Keywords: MOFs, organic synthesis, solid-liquid separation, uranium

Повний текст джерелаThe indoor air pollution awareness of general public and the increasing demands of regulations / recommendations, combined with a need to stand out from the competition, make limiting the concentration of VOCs (VOCs : volatile organic compounds ) in the air cockpit crucial for the automotive industry. For example, inside a vehicle, the VOCs are originated from the outside air by combustion and evaporation of fuel. However, unlike other pollutants, it may also have an inner origin from the desorption of existing chemical substances used in the manufacture of the vehicle. Thus, the capture of VOCs by adsorption is one of the challenging techniques today. In this context, activated carbon and zeolite based VOC abatement are effective and least expensive but suffers some limitations in stability, selectivity and regeneration. The aim of this thesis was to study an alternative class of 'hybrid' adsorbents i.e. Metal-Organic Frameworks (MOFs). These porous crystalline materials are built by the association of inorganic bricks connected by organic ligands. They have highly tunable structural diversity,chemical composition (metal:ligand) and porosity (pore size, surface area and pore volume). Moreover, they possess almost infinite ability to vary both the metal center and the organic ligand that is not found at this level in zeolites and activated carbons. The work was to evaluate the performance of a series of ten MOFs, having diverse architecture (size and shape of the pores, rigid or flexible networks ...), chemical properties (acidity, redox, hydrophilic / hydrophobic, ...) and stability (water temperature). In addition to the usual characterization (X-ray diffraction, thermogravimetric analysis, infrared spectroscopy, porosimetry N2 at 77K), Infra-Red spectroscopy operando was performed to simulate the behavior of these MOFs in the presence of VOCs in conditions as close as possible to the reality. Furthermore, the most promising adsorbents were scaled up (50-100 g) and formatted/fabricated as pellets and tested for environmental simulation chamber

Повний текст джерелаSol-gel coatings for corrosion protection of metals are a good alternative to replace toxic chromate treatments. The present work was focused on the incorporation of inorganic fillers functionalized with organic corrosion inhibitors in a sol-gel coating. Talc-like phyllosilicates were selected as inorganic fillers. Talc lamellar structure was evidenced but, in contrast with natural talc, the large specific surface allows talc-like phyllosilicates to be easily functionalized by covalent grafting of corrosion inhibitors. Small size (about 300 nm) and hydrophilicity of the particles are also important parameters because they improve the talc-like phyllosilicates dispersion in sol-gel coatings. Grafted and non-grafted materials incorporation in coatings deposited on a XC35 carbon steel permitted to reinforce barrier properties and to decrease metal corrosion. On the other hand, it was impossible to conclude about grafted corrosion inhibitors efficiency due to the low adhesion of the coating on the metal substrate
