Abstract:

The major innovation of this work is an establishment of a novel chiral separation process using preferential crystallization coupled with a membrane barrier. This hybrid process was proved to be promising from a significant increase in product yield and purity compared to existing chiral separation processes. This work sets up a process design platform to extend the use of this hybrid process to a separation of other mixtures. This novel process especially is a promising alternative for chiral separation of pharmaceutical compounds which include more than fifty percent of approved drugs wor

Les nonlinéarités dans les systèmes nanomécaniques peuvent provenir d’effets dispersif ou dissipatif et ce dans divers systèmes (résistifs, inductifs et capacitifs).

Abstract:

A variety of liquid crystalline (LC) materials have been examined as potential membrane separation materials. The order present in the LC phases has measurable effects on solute sorption, diffusivity, permeability, and selectivity, and can thus be used to tune the transport and separation of different species. The current work has focused on polymer dispersed liquid crystal (PDLC), linear butadiene diol based side chain liquid crystalline polymer (LCP), and linear and crosslinked acrylate based LCP membranes. The focus was primarily on the separation of propylene and propane, a separation of

Abstract:

The recent demonstration of strong interactions between optical force and mechanical motion of an optomechanical structure has led to the triumphant result of mechanical ground-state cooling, where the quantum nature of a macroscopic object is revealed. Another intriguing demonstration of quantum physics on a macroscopic level is the measurement of the Casimir force which is a manifestation of the zero- point energy. An interesting aspect of the Casimir effect is that the anharmonicity of the Casimir potential becomes significant when the separation of microscale objects is in the sub-100nm re

Abstract:

In cell biology and chemistry, total internal reflection microscopy (TIRFM) has proven to be a useful technique that allows the probing of cellular processes with high-signal-to-noise ratio imaging. However, samples on solid substrates limit the accessibility to probe processes on extracellular membrane surface closest to the microscope objective. Colloidal crystals provide a porous alternative to the traditional solid substrates. Thin crystals exhibit optical properties similar to that of a fused silica coverslip allowing for TIRFM in the same manner as with a typical coverslip as demonstrate

Abstract:

Lipopolysaccharide (LPS) is the glycolipid that comprises the outer leaflet of the Gram-negative outer membrane (OM). Because it is essential in nearly all Gram-negative species, and because it is responsible for making these bacteria impervious to many types of antibiotics, LPS biogenesis has become an important area of research. While its biosynthesis at the cytoplasmic face of the inner membrane (IM) is well studied, the process by which it is removed from the IM, transported across the aqueous periplasmic compartment, and specifically inserted into the outer leaflet of the OM is only begin

Robust control over nanoparticle (NP)-cell interactions is essential to the rational design of safe, advanced, and tailored nano-bio technologies.

Despite numerous research efforts, the propensity of surface-modified NPs to interfere (or not) with the organization and function of cell membranes is still far from clear due to the inherently complex and dynamic nature of these biological barriers.

Abstract:

Cette thèse porte sur la physique des ondes, dans le but de contrôler leur propagation. Nous cherchons à mettre en évidence des phénomènes communs à toutes les ondes grâce à un système expérimental modèle utilisant les ondes à la surface d’un liquide. Plus précisément, nous choisissons de travailler avec des ondes hydroélastiques en couvrant la surface du liquide avec un film élastique. Les déformations élastiques de cette membrane sont couplées aux mouvements du fluide, de sorte qu’en modifiant les propriétés de la membrane nous pouvons agir sur la propagation des ondes. Ainsi, en changeant l

Abstract:

Les systèmes micro et nanoélectromécaniques sont largement explorés pour des applications en photonique intégrée et pour sonder des phénomènes physiques fondamentaux. Un important corpus de recherches se concentre sur les dynamiques linéaires et non linéaires des résonateurs couplés ainsi que leurs comportements collectifs. Cette thèse présente la conception, la fabrication et la caractérisation de membranes opto-électromécaniques nanométriques couplées, dans les régimes linéaires et non linéaires, et est divisée en trois parties principales. La première partie détaille la conception, l'optimi

Abstract:

Non-stoichiometric strontium iron oxide is described by an abbreviated formula SrFeOx (2.5 ≤ x ≤ 3.0) exhibits a variety of interesting physical and chemical properties over a broad range of temperatures and in different gaseous environments. The oxide contains a mixture of iron in the trivalent and the rare tetravalent state. The material at elevated temperature is a mixed oxygen conductor and it, or its derivatives,can have practical applications in oxygen conducting devices such as pressure driven oxygen generators, partial oxidation reactors in electrodes for solid oxide fuel cells (SOFC).

Abstract:

The oxygen permeation flux through the perovskite membrane made of Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) has been measured as a function of both the temperature and the oxygen pressure gradient across the membrane. A simple model for the surface exchange fluxes was used to understand the mechanism of the oxygen transport. The limiting step of the oxygen transport was found to be the bulk diffusion for the BSCF perovskite at temperatures above 700 oC. Furthermore, the oxygen vacancy diffusion coefficient (Dv) can be deduced from the dependence of the oxygen permeation flux on the oxygen pressure grad
