Abstract:

The present research activity has been focused on surface modifications of polymers in order to enhance their flame retardancy and gas barrier properties. The work has been split into two different topics: i) fabric flame retardancy and ii) gas barrier coatings for packaging applications. Within the first topic different strategies have been applied in order to enhance the flame retardancy of synthetic poly(ethyleneterephthalate) fibres and their blends with cotton. The first strategy deals with the single step nanoparticle adsorption in a finishing-like process. In order to enhance the surf

Abstract:

The problem of homogenization the nanostructured materials placed in DC magnetic field has been discussed. The experimental data are obtained using metallic superlattices, metal-dielectric thin films and 3D-nanostructured materials. All these materials contain ferro- or ferrimagnetic component. The trans-mission and reflection coefficients were measured on the waves of millimeter waveband. It has been shown that the experimental frequency spectra of the coefficients in zero magnetic field can be described by the effective conductivity and dielectric permittivity.

Abstract:

The accelerated emergence of drug resistant bacteria is one of the most serious problems in healthcare and the difficulties in finding new antibiotics make it even more challenging. To overcome the action of antibiotics bacteria develop effective resistance mechanisms including the formation of biofilms. Biofilms are bacterial communities of cells embedded in a self-produced polymeric matrix commonly found on medical devices such as indwelling catheters. When pathogens adopt this mode of growth on the surface, they effectively circumvent host immune defences and antibiotic therapy, causing sev

A number of investigators have reported enhancement in oxidation and wear resistant of carbon-carbon composites (CCC) in the presence of protective coating layers. However, application of a surface and subsurface coating system that can preserve its oxidation and wear resistance along with maintaining lubricity at high temperature remains unsolved. To this end, thermodynamically stable protective oxides (ZnO/Al2O3/ZrO2) have been deposited by atomic layer deposition (ALD) to infiltrate porous CCC and graphite foams in order to improve the thermal stability and wear resistance in low and high

Abstract:

Friction and wear mitigation is typically accomplished by introducing a shear accommodating layer (e.g., a thin film of liquid) between surfaces in sliding and/or rolling contacts. When the operating conditions are beyond the liquid realm, attention turns to solid coatings. Solid lubricants have been widely used in governmental and industrial applications for mitigation of wear and friction (tribological properties). Conventional examples of solid lubricants are MoS2, WS2, h-BN, and graphite; however, these and some others mostly perform best only for a limited range of operating conditions

Abstract:

Metal oxide nanolaminate films are potential high temperature solid lubricants due to their ability to exhibit significant plasticity when grain size is reduced to the nanometer scale, and defective growth structure is achieved by condensation of oxygen vacancies to form intrinsic stacking faults. This is in contrast to conventional microcrystalline and single crystal oxides that exhibit brittle fracture during loading in a sliding contact. This study emphasizes the additional effect of growth orientation, in particular crystallographic texture, on determining the sliding friction behavior i

Currently available solid lubricants only perform well under a limited range of environmental conditions. Unlike them, oxides are thermodynamically stable and relatively inert over a broad range of temperatures and environments. However, conventional oxides are brittle at normal temperatures; exhibiting significant plasticity only at high temperatures (>0.5Tmelting). This prevents oxides' use in tribological applications at low temperatures. If oxides can be made lubricious at low temperatures, they would be excellent solid lubricants for a wide range of conditions. Atomic layer deposition (AL

Abstract:

Le but de cette thèse est d’étudier le processus de la génération d’harmoniques d’ordre élevé (HHG, de l’anglais high-order harmonic generation) dans des solides et la possibilité d’augmenter l’efficacité de la génération en exploitant l’exaltation locale du champ incident dans des nanostructures. La HHG dans les gaz est connue depuis plusieurs décennies et a été étudiée en détails, par contre la HHG dans les solides a été démontrée pour la première fois en 2011. Différents processus comme les oscillations interbandes et intrabandes y jouent un rôle fondamental. Le processus exact est toujours

Abstract:

<p>In this report a model analysis is presented for three different nanostructured layers: silicon nanotips (SiNTs), gold nanosandwiches and Split Ring Resonators (SRR). The last two materials are metamaterials and both may show a negative refraction index. Experimental data are obtained for every sample using a variable angle spectroscopic ellipsometer. For the gold nanosandwiches, also an infrared ellipsometric measurement is done. For complex layers like these, advanced modeling is necessary. A recently developed analysis program including options for both anisotropic permittivity and perme

Abstract:

Mannan is a polymannose isolated from the cell wall of Saccaromyces cerevisiae and has strong binding affinity to mannose receptors on antigen presenting cells (APCs), such as dendritic cells and macrophages. Mannan-functionalized nanomaterials or nanostructures are thus of high interests in studying immune responses towards fungi. In this work, we investigated the fabrication of mannan-coated silver nanostructures using a laser-deposition technique. Specifically, two different starting materials were applied for laser-deposition. One is a mixture solution of AgNO3 and mannan, and the other on

Abstract:

A challenge exists for understanding the origin of color for structurally colored, 3-dimensional bioorganic nanostructures, such as the scales of butterflies, beetles, and moths. Complex, hierarchical structures found within such scales create the overall scale appearance. The controlled alteration of color through material deposition and the addition of new optical functionalities to such structures are other areas of scientific interest. This dissertation addresses these challenges with a first-of-its-kind, systematic isolation (deconstruction) of scale component nanostructures, followed by

Abstract:

The prototypical exciton model of two interacting Dirac particles in graphene was analysed by Sabio et al, Phys. Rev. B 81, 045428 (2010), and it was found that in one of the electron-hole scattering channels the total kinetic energy vanishes, resulting in a singular behaviour. We show that this singularity can be removed by extending the quasiparticle dispersion, thus breaking the symmetry between upper and lower Dirac cones. The dynamics of an electron-electron pair are then mapped onto that of a single particle with negative mass and anisotropic dispersion. We show that the interplay betwee

Cette thèse se concentre sur l'étude numérique de l'interaction laser ultrabref avec les diélectriques transparents. En particulier, le phénomène d'auto-organisation des nanoréseaux dans la silice est discuté et un modèle multiphysique est proposé pour expliquer le mécanisme de leur formation. Les nanoréseaux en volume sont des nanostructures périodiques de périodicité sub-longueur d'onde, qui consistent en un matériau moins dense et sont générés par une irradiation laser multi-impulsionnelle femtoseconde dans certains verres, cristaux et semiconducteurs. Leur origine physique ainsi que les co

Abstract:

Le travail de thèse s’inscrit dans le cadre du projet GOLEM et de la manipulation parallèle robotisée d’objets de taille submillimétrique. L’un des enjeux majeurs de cette échelle est de développer des nouvelles méthodes de manipulation parallèle pour réussir à assembler des objets de quelques centaines de micromètres avec un haut cadencement. A cette échelle, la robotique série est limitée par la fréquence et les phénomènes physiques mis en jeu. Il faut donc trouver de nouvelles solutions dédiées à ces échelles. Pour résoudre ce verrou scientifique, ce travail de thèse propose une approche or
