Full textThis work of thesis approaches the problems of the development of packings intended for reactive distillation. Methodology to be followed is so applied in the case of ceramic foam in Silicon Carbide. The hydrodynamic behaviour was studied as well as the mass transfer efficiency demonstrating the possible application of ceramic foam as a packing for distillation. The aspect of the catalytic activation of the support was then developed in order to determine the most efficiency method in terms of catalytic activity making it possible to approach reference packing, the KATAPAK. The coating of Amberlyst 15 then appeared as the most interesting way for the possible application of coating foam as catalytic packing for reactive distillation

Full textThe first part of this thesis deals with the prediction of the mean jet wiping flow, i.e. the film thickness distribution in the wiping region. A lubrication model is developed for that purpose, which is simplified to a zero-dimensional model giving directly the final thickness
In the second part, the prediction of splashing occurrence in jet wiping is addressed. The splashing phenomenon in jet wiping is featured by the ejection of droplets from the runback flow, and it constitutes a physical limit to the process. An experimental investigation is conducted on a water model facility, and based on a phenomenological description, a dimensionless correlation in terms of film Reynolds number and jet Weber number is derived for splashing occurrence. The latter is perfectly well validated with observations on industrial lines.
The last part of this thesis is dedicated to the study of the unsteady phenomena occurring on the free surface of the liquid film downstream wiping. This phenomenon has never been understood nor characterized up to now. In the present research, undulation is investigated both theoretically and experimentally. Two model test facilities with dedicated measurement techniques have been designed and constructed. They allow performing parametric studies of the undulation characteristics (amplitude, wavelength, wave velocity), and analyzing the jet/film interaction.

Full textIglesias, Hernandez Luis. "Resonant microsystems for hydrogen gas detection without functionalized coating." Thesis, Bordeaux, 2020. http://www.theses.fr/2020BORD0112.
Full textHydrogen is a hazardous gas that becomes explosive above a concentration of 4% in air. As a result, many applications where hydrogen is either used or produced require hydrogen sensors to ensure that this limit is never reached. These applications include radioactive waste monitoring, clean energy production or more generally industrial gas monitoring. Most existing sensing devices currently on the market are based on the use of a specifically engineered chemical component or film, which in most cases is not stable over time, lasting usually a few months. This has led to the development of methods that rely on physical sensing mechanisms rather than on chemical ones for the detection of hydrogen: these methods have the advantage of being stable over much longer periods of time. In the context of radioactive waste monitoring, previous work has shown that uncoated (no chemical film) microcantilevers are capable of detecting hydrogen gas up to 0.01% by measuring their change in resonant frequency. This work extends this study by adding the ability to distinguish hydrogen from potential interfering gases. In the case of microcantilevers, gas discrimination is achieved by measuring not only the density of the gas but also its viscosity with the measurement of both the resonant frequency and the quality factor. Capacitive micromachined ultrasonic transducers (CMUTs) have also been used as an alternative to microcantilevers. With the CMUTs, both sound velocity and acoustic attenuation have been measured by a time of flight setup instead of device measurements at resonance. In the case of attenuation measurement, a method for obtaining good selectivity of hydrogen measurement against interfering gases such as carbon dioxide and methane has been developed

Full textSilicon Carbide (SiC) fulfills many requirements, e.g. a high robustness in terms of corrosion, which makes it a suitable Material for ceramic membranes. The aim of this work was to produce ceramic membranes out of porous liquid phase sintered Silicon Carbide (LPS-SiC). As additives Alumina and Yttria were used. The SiC based on commercial abrasive powders F1200 (Membrane) and F500 (Substrate). Different techniques of membrane formation were applied in order to find the optimum processing procedure: Dip Coating, Electrophoretic Deposition (EPD), Pressure Filtration and the usage of so called Transfer Tapes, a blend of Polyacrylate and ceramic powders). For the slip based methods a water based system was developed without the need of organic additives. A pure electrostatic stabilization was facilitated by solving Yttria with Hydrochloride Acid and precipitation, resulting in the coverage of the SiC particles with finely dispersed Yttria. The EPD was not successful due to a undefined specific resistance of the substrate. The pressure filtration turned out to be the best, most versatile method, leading to defect free membranes with the lowest measured surface roughness. The pressure ranged between 2*10E4 and 1*10E5 Pa. Higher pressure lead to finer pores. The Dip Coating was controlled only by the solids content. Membranes by Dip Coating showed macroscopic defects. As a new concept for ceramic membrane fabrication the Transfer Tapes needed further investigation. The direct gluing on the substrate was possible. The thickness of the membrane was limited to 50 microns in order to keep free of cracks. The Transfer Tapes exhibited pronounced fluctuations in the debinding and sintering shrinkage, leading to increased tension during sintering. Furthermore cavities, (e.g. big pores) were bridged. Both effects lead to increased tension during sintering

Full textThe cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied. In an attempt to make these coatings bioactive and useful for bone-anchored implants, an amelogenin protein mixture (EMD), has been immobilized in these thin polyelectrolyte multilayer (PEM) films. Multilayers were also built by LbL deposition of the natural biomacromolecules collagen (Col) and hyaluronic acid (HA). Multilayer films of these two extra-cellular biomacromolecules should be of interest for use as a scaffold for tissue engineering.
The buildup of the multilayer films has been followed in situ, using ellipsometry, quartz crystal microbalance with dissipation (QCM-D), and dual polarization interferometry (DPI). The studied PLL/PGA multilayers were found to be highly hydrated, and to exhibit a two-regime buildup behavior, with an initial “slow-growing” regime, and a second “fast-growing” regime with a linear growth in film thickness and more than linear growth in mass. A net diffusion of polypeptides into the film during the buildup led to an increase in density of the films for each layer adsorbed. A change in density was also observed in the Col/HA film, where HA penetrated and diffused into the porous fibrous Col network.
The formed PLL/PGA films were further found to be rather stable during drying, and post-buildup changes in temperature and pH, not losing any mass as long as the temperature was not raised too rapidly. The film thickness responded to changes in the ambient media and collapsed reversibly when dried. A swelling/de-swelling behavior of the film was also observed for changes in the temperature and pH.
The EMD protein adsorbed to silica surfaces as nanospheres, and could by itself form multilayers. The adsorption of EMD onto PLL/PGA multilayer films increased at lower pH (5.0), and EMD could be immobilized in several layers by alternate deposition of EMD and PGA.

Full textThe aim of this study is to investigate the influence of pressure on cavitation phenomenon. During propagation of an acoustic wave in solution, cohesion forces within the liquid can break leading to formation of cavitation bubbles. Fed with solvent vapors and dissolved gases, these bubbles grow and implode violently after reaching critical size. For the study of electrochemical processes assisted by ultrasound, cavitation control is interesting. By limiting the presence of dissolved gases and using low vapor pressure solvents, it was possible to control cavitation phenomenon. Results show big decrease in cavitation for pressures below 60 kPa. Respective contributions of cavitation and acoustic streaming within global hydrodynamic agitation have been determined thanks to electrodiffusional techniques. A cavitating medium enables increase in global agitation of about 30% in comparison to a monophasic medium (without cavitation) in the case of a low frequency ultrasound irradiation. Influence of cavitation on self-assembled monolayers (SAMs) grafting and electrochemical coatings of silver and copper in ionic liquids has been assessed. In the case of SAMs, cavitation is beneficial towards organic film grafting kinetics and carbon chain orientation on the surface. Indeed, for 15 minutes modification under ultrasound irradiation without cavitation, electrochemical blocking rate is 3.6 times higher than in silent conditions. With cavitation, this blocking rate shows an additional 50% increase. Concerning electrolytic coatings, a decrease in crystallite size is evidenced with increase in cavitation activity. Indeed, a decrease of 30% and 50% was observed for copper and silver coatings, respectively
