▼ : Soit E→P1 une surface elliptique sur Q de base P1 non triviale. On s’intéresse à la Zariski-densité des points rationnels de E . Il est conjecturé que le signe de l’équation fonctionnelle d’une courbe elliptique est relié à la parité du rang de celle-ci. Modulo cette conjecture, il est suffisant de démontrer que le signe des fibres de E varie pour démontrer la Zariski-densité de E (Q). Un théorème conditionnel de Helfgott garantit que le signe moyen d’une surface non isotriviale est strictement compris entre -1 et 1. Dans le cas où E possède une place générique de réduction multiplicative, le signe moyen serait nul. Ce travail est conditionnel à deux conjectures de théorie analytique des nombres : la conjecture sans facteur carré et la conjecture de Chowla. L’objectif principal de cette thèse est d’éviter les conjectures utilisées par Helfgott pour démontrer la variation du signe sur les surfaces elliptiques non triviales. On réussit à se passer de la conjecture sans facteur carré sous certaines hypothèses techniques. On démontre ainsi (sous l’hypothèse de la conjecture de parité) la densité des points rationnels sur certaines surfaces elliptiques dont les coefficients sont des polynômes de degré arbitraire. Une surface de Del Pezzo de degré 1 est reliée par l’éclatement d’un point canonique à une surface elliptique rationnelle. On démontre inconditionnellement la densité des points rationnels dans plusieurs cas par des arguments géométriques. On étudie aussi la variation du signe de l’équation fonctionnelle pour des surfaces elliptiques rationnelles isotriviales et on cerne des conditions pour que le signe soit fixé. Dans le cas où le signe est +1, on en déduit des exemples de surfaces elliptiques non triviales dont les points rationnels pourraient ne pas être denses.
Let E→P1 be an non-trivial elliptic surface over Q with base P1. We are interested in the Zariski density of the rational points of E. It is conjectured that the root number of an elliptic curve E has the same parity as its rank. Assuming this conjecture, it is enough to show that the root number of the fibre of E varies to prove the Zariski density of E(Q). A conditional theorem of Helfgott garanties that the average root number of a non-isotrivial elliptic surface is strictly between -1 et 1. In the case where E has a generic place of multiplicative reduction, the average root number should be zero. This work is conditional to two analytic number theory conjectures : the squarefree conjecture and the Chowla conjecture. The main aim of this Ph.D thesis is to avoid the conjectures used by Helfgott when proving the variation of the root number on non-trivial elliptic surfaces. We manage to drop the squarefree conjecture assumption under some technical hypothesis. We show thus (under the parity conjecture) the density of the rational points on some elliptic surfaces whose coefficients have arbitrary large degree. Blowing up the anticanonical point on a del Pezzo surface of degree 1, one obtains a rational elliptic surface. We show unconditionally…

▼ We give a new characterization of elements in the Veech group of a translation surface. This provides a computational test for Veech group membership. We use this computational test in an algorithm that detects when the Veech group is a lattice (has co-finite area), and in this case computes a fundamental polygon for the action of the Veech group on the hyperbolic plane. A standard result, essentially due to Poincaré, provides that a complete set of generators for the Veech group can then be obtained from the side pairings associated to this fundamental polygon.
Our approach introduces a new computational framework used to formulate a membership criterion for the Veech group of a compact translation surface (X,ω). We represent (X,ω) on a certain non-compact translation surface O that can be used to represent any translation surface within the SL(2,ℝ) orbit of the translation equivalence class of (X,ω). The surface O has an easily computed SL(2,ℝ)-action. When this action is restricted to the translation surface representations mentioned above, it corresponds to the usual SL(2,ℝ)-action on the set of equivalence classes of translation
surfaces. The Veech group of a compact translation surface is therefore the stabilizer of its representation on O.

▼ The mechanics of biological contact are important in
many natural processes, motivating extensive study of biological
adhesive systems as well as attempts at biomimickry through
microfabricated adhesive
surfaces. Improved understanding of the
physical mechanisms of biological adhesion is essential for further
progress in the design of advanced adhesive systems so that natural
systems are not just copied, but are ultimately improved upon. The
work presented here focuses on two broad classes of biological
contact problems related to the key design variables of surface
topography and material properties: geometric adhesion enhancement,
where the force and/or work required to separate two
surfaces are
increased solely through the surface geometry, and mixed mode
adhesive contact, i.e., combined normal and tangential loading or
straining, of viscoelastic or otherwise dissipative adhesive
interfaces. An analytical contact model for axisymmetric concave
surfaces is shown to predict higher adhesive pull-off forces for a
range of these geometries than for flat punches of equal size, and
experiments on gelatin validate the predictions of the model.
Axisymmetric sinusoidal wavy
surfaces are also studied
analytically, and it is shown that low-amplitude waviness can
enhance adhesion through both strengthening and toughening of the
interface. A model is developed for the wavy surface so that the
adhesive pull-off forces in the JKR-DMT transition regime can be
studied, and significant adhesion enhancement due to surface
topography is seem to be limited to the JKR regime. Mixed mode
adhesive contact is studied by introducing a phenomenological model
for increased effective work of adhesion with increasing phase
angle of mode mixity, allowing the energy dissipation due to
viscoelasticity or irreversible interfacial processes seen in
contact experiments of glass spheres on PDMS to be captured. This
phenomenological model is incorporated into an analysis of mixed
mode contact of axisymmetric wavy
surfaces, and the mechanisms
which enhance adhesion are shown to be linked to enhanced static
sliding resistance. These results highlight the importance of
surface topography and material behavior in adhesive
contact.

▼ We analyze the cutting sequences associated to
geodesic flow on a large class of translation
surfaces, including
Bouw-Möller
surfaces and certain rectilinear
surfaces. We give a
combinatorial rule that relates a cutting sequence corresponding to
a given trajectory, to the cutting sequence corresponding to the
image of that trajectory under the parabolic element of the Veech
group. This extends previous work for regular polygon
surfaces to a
larger class of translation
surfaces. We find that the
combinatorial rule is the same as for regular polygon
surfaces in
about half of the cases, and different in the other
half.

▼ In this paper we consider the behavior of certain surfaces at
certain boundary points. The surfaces under consideration satisfy
a topological definition and are of 2-dimension in 3-dimensional
Euclidean space with the boundary a finite set of straight line
segments. It is shown that the surface of minimum area with a given
boundary is locally Euclidean at all non-vertex. boundary points.
The key to the proof is a theorem in 1 which itself concerns the
behavior of a set of points under very restricted conditions. It
is shown in 1 that for almost all interior points the conditions
of the lemma are satisfied.
This paper first shows that the part of the given surface
interior to some sphere centered at any non-vertex boundary point
lies near a plane passing through the point in question. Secondly
it is shown that for any point of the surface lying in the sphere
the surface interior to any smaller neighborhood of that point lies
near a plane. "Near" here refers to nearness with respect to the
radius of the sphere or neighborhood in consideration.
From these conditions we may construct a bounded point set
satisfying the hypothesis of the aforementioned theorem. The
theorem of this paper follows immediately.

▼ We construct projective moduli spaces of semistable objects on an Enriques surface for generic Bridgeland stability condition. On the way, we prove the non-emptiness of MH,Ys(v), the moduli space of Gieseker stable sheaves on an Enriques surface Y with Mukai vector v of positive rank with respect to a generic polarization H. In the case of a primitive Mukai vector on an unnodal Enriques surface, i.e. one containing no smooth rational curves, we prove irreducibility of MH,Y(v) as well. Using Bayer and Macr`{i}'s construction of a natural nef divisor associated to a stability condition, we explore the relation between wall-crossing in the stability manifold and the minimal model program for Bridgeland moduli spaces. We give three applications of our machinery to obtain new information about the classical moduli spaces of Gieseker-stable sheaves: 1) We obtain a region in the ample cone of the moduli space of Gieseker-stable sheaves over Enriques surfaces. 2) We determine the nef cone of the Hilbert scheme of n points on an unnodal Enriques surface in terms of its half-pencils and the Cossec-Dolgachev φ-function. 3) We recover some classical results on linear systems on unnodal Enriques surfaces and obtain some new ones about n-very ample line bundles.

▼ A continuum approach is used to model a twin lamella as a flat section embedded in an elastically isotropic medium under applied stresses. The twin formation energy as the sum of self energy of the disclination dipole, and the elastic interaction between the disclination dipole and the applied strain, associated with the twin-matrix interfacial energy was calculated. The minimization of the formation energy with respect to the dimensions of the lamella is related to the twin nucleation, which gives the condition for when twin nucleation is energetically favorable. Based on the assumption that the nucleation of twin is a thermally activated process, the critical stress dependent on the sample diameter was obtained, that is the smaller the sample size, the larger the apparent strength. Compared to the conventional infinite model related to twinning, the effect of surface or boundary was studied. Theoretical analysis and molecular dynamics simulations are conducted to study systematically surface eigen-displacement and surface Poisson’s ratios of solids, which play essential roles in surface energy, surface strain and surface stress. Face-centered cubic (001) Au thin films were taken as typical examples to illustrate the physical picture. The surface eigen-displacement is a critical surface strain at the equilibrium state after normal relaxation and thus an intrinsic surface property. Surface Poisson’s ratios are also intrinsic surface properties. Combining surface eigen-displacement and surface Poisson’s ratios with surface eigen-stress and surface tangential elastic constants lays foundations of surface elasticity of solids. Taking advantages from both Gibbs and McLean adsorption isotherms, we develop a Gibbs-approach based adsorption isotherm for grain boundary (GB) segregation in nanograined (ng) polycrystals. An excess GB thickness is introduced to describe the excess of GB atomic volume in comparison with the atomic volume in lattice. The GB bulk modulus is determined with the excess GB thickness and a universal function. The newly developed adsorption isotherm is able to analyze simultaneously stresses, concentrations and their coupling behaviors in grains and GBs. Numerical calculations and plots are conducted to illustrate the theoretical analysis. The results show that the apparent solute concentration could be greatly enhanced in ng materials, due to a large grain boundary volume fraction and a considerable increase in the lattice concentration that is, in turn, boosted by the concentration-induced stresses. The Gibbs-approach based adsorption isotherm for nanograined polycrystals is applied to the H-Pd solid solutions. Using the published experimental data of lattice strain and sample strain of the nanograined Pd, with an averaged grain size of 10 nm and in thermodynamic equilibrium with a H2 partial pressure, we determined H concentrations and stresses, as a function of the H2 partial pressure, in both grains and grain boundaries. More importantly, we determined the intrinsic…

▼ We will prove the Birman exact sequence as motivated by the study of mapping class groups. In order to do so we introduce basic concepts and theorems about surfaces, exact sequences, mapping class groups, higher dimensional homotopy groups, and fiber bundles. In particular, the proof of the Birman exact sequence depends heavily on the long exact sequence of homotopy groups of a fiber bundle, and a majority of the thesis is devoted to establishing this sequence.

▼ Sur une surface superhydrophobe, les gouttes d'eau rebondissent ou roulent grâce au piégeage de poches d'air entre les microstructures (état « Fakir »). Cependant, cette même surface est inefficace vis à vis d'une goutte d'alcool qui s'imprègne dans les aspérités. Afin d'étendre l'effet superhydrophobe à une large gamme de liquides, il est nécessaire de fabriquer des microstructures présentant une géométrie dite « ré-entrante ». Ces surfaces sont alors dites superomniphobes. Dans un premier temps, nous présentons deux procédés de fabrication permettant d'obtenir de telles surfaces à base de polymère, ou à base de polymère et de nitrure de silicium. Dans un second temps, nous étudions les propriétés d'adhésion (hystérésis d’angle de contact) de ces surfaces en fonction des paramètres géométriques des microstructures. Les résultats mettent en évidence un effet de saturation non décrit par les modèles théoriques existants. Afin de contribuer à la compréhension des mécanismes physiques responsables de ce phénomène, nous présentons une expérience permettant d'imager la déformation de l'interface liquide sur ces surfaces. Les mesures montrent la formation de micro ponts liquides durant le démouillage. Nous montrons que l'analyse des modes d'instabilité de ces ponts liquides permet de justifier qualitativement la saturation observée. Ces expériences mettent également en évidence le dépôt de nano-volumes de liquide sur les structures suite au démouillage de la surface. L'hétérogénéité de ces dépôts est corrélée à la dynamique de la ligne triple. Ce phénomène présente des perspectives intéressantes pour le dépôt contrôlé et passif de colloïdes ou biomatériaux.
On a superhydrophobic surface, water drops rebound and roll off due to trapping of air pockets between micro or nano structures (“Fakir” state). However, the same surface is inefficient toward alcohol drops which spread in the asperities.In order to extend the superhydrophobic effect to a wide range of liquids, it is necessary to design microstuctures with a “re-entrant” geometry. These surfaces are then called superomniphobic. In a first time, we present two microfabrication processes enabling to obtain such surfaces in polymer, or in polymer and silicon nitride. In a second time, we study the adhesion properties (contact angle hysteresis) as a function of microstructures geometrical parameters. The results point out a saturation effect which is not described by actual models. In order to better understand the underlying physical mechanisms responsible for this phenomenon, we present an experiment enabling to visualize the liquid interface deformation on these surfaces. Measurements show that dewetting occurs through the formation of micro capillary bridges. By analyzing the instability modes of these liquid bridges, we show that it is possible to qualitatively demonstrate the observed saturation effect. The experiments also point out the presence of nano-scale liquid volumes on the micro-structures resulting from de-wetting of the surface. The heterogeneities of…

▼ Wetting layer at surfaces plays a very important role in the growth of thin film and nanostructures as it defines a modified surface layer on which other structures are grown. The wetting layer also changes the physical and electronic properties of the surface and hence it can influence the growth and properties of nanostructures which sit on top. In this thesis, we will characterize the wetting layers and the nanostructures on top using Low Energy Electron Microscopy/Diffraction (LEEM/LEED), and Spectroscopic PhotoEmission and Low Energy Electron Microcopy. We will examine my research on two different metal on semiconductor systems, Pb/Si(111) and Fe/ZnS(001), as well as carbon-based layers on metal surfaces, C60/Pt(111) and graphene/Ru(0001). The main accomplishments of this thesis are summarized as follows. An exceptionally unusual mass transport behavior has been discovered in the dense Pb wetting layer on the Si(111) surface. Mass transport is studied by observing non-equilibrium coverage profile evolution with LEEM and micro-LEED. During equilibration, an initial coverage step profile produced by laser induced thermal desorption retains its shape as it is displaced linearly in time. This contrasts with the profile broadening and gradual time-dependent evolution that is expected from classical consideration. Equally inexplicable in the classical context is a small but discrete coverage discontinuity in the wetting layer that expands radially outward like a wavefront. Our observations signal the presence of a very novel super-diffusive mass transport mechanism, which is much more efficient at transporting mass across a surface than stochastic atomic hopping processes. In the study of Fe/ZnS(001), nanowires of high aspect ratio are prepared by epitaxial growth and we observed a complex and strongly temperature dependent nanowire growth behavior. Two kinds of magnetic nanowires have been found, one of which is pure Fe and the other may contain some kind of iron sulfide, probably greigite (Fe3S4), at least on the surface. C60 on the Pt(111) surface forms two ordered phases: (√13x√13)R13.9° and (2√3x2√3x)R30° that normally coexist. In the current work, the two phases are isolated experimentally and intensity vs. voltage, I(V), curves are measured. Their structural details are extracted by combined dynamic LEED analysis of I(V) curves and density functional theory calculations. Our results show that both phases involve substrate reconstruction, producing atom vacancies directly under the C60 molecules. In graphene/Ru(0001), we have found no evidence of broken mirror symmetry in the diffraction peak intensities measured with micro-LEED on a length scale of 250 nm to support the recent report of chirality in this system. Instead, small rotations of the graphene lattice from orientational coincidence with the substrate are evident in moiré-derived diffraction features. Additionally, bias of the lattice rotation on the two different surface terminations of the hcp substrate has been found.

▼ Micrometre-sized colloidal particles can be viewed as large atoms with tailorable size, shape and interactions. These building blocks can assemble into extremely rich structures and phases, in which the thermal motions of particles can be directly imaged and tracked using optical microscopy. Hence, colloidal particles are excellent model systems for studying phase transitions, especially for poorly understood kinetic and non-equilibrium processes. In this thesis, we report a dye-induced attraction between colloidal spheres which can be finely tuned by temperature. It opens the way to study surface physics in colloidal model systems (Chapter 2). We epitaxially grew high-quality colloidal crystals with free surfaces, and observed the surface premelting, grain-boundary-mediated 2D melting and isostructural solid-solid transitions at the single-particle level for the first time. Analogues to the surface liquid in premelting, we discovered a layer of square lattice on the surface of the bulk triangular lattice. In Chapter 3, we focus on the surface premelting and melting in colloidal crystals. We find that monolayer colloidal crystals exhibit incomplete premelting, with a constant liquid-layer thickness. In contrast, two- and three-layer crystals exhibit conventional complete melting, with the thickness of the surface liquid diverging as approaching the melting point. Incomplete premelting in the monolayer crystals is triggered by a bulk isostructural solidsolid transition and truncated by the first order homogeneous bulk melting. The interplay between surface premelting, bulk melting and solidsolid transitions challenges both premelting and melting theories. In Chapter 4, we report the discovery of a thin layer of ☐-lattice formed on the surface of the Δ-lattice of a colloidal thin-film crystal. The surface crystal wets both the bulk crystal and the surface liquid, thus effectively reduce the interfacial energy. The wetted structure also exists in the epitaxial growth process. The discovered phenomenon provide a novel way to tune the surface properties of crystals.

▼ Central Composite Designs (CCDs) with cuboidal and spherical regions are among the most popular experimental designs for studying response
surfaces. Cuboidal regions are typically used when the experimenter believes the levels of one or more of the factors are bounded while a spherical region is employed when there are no restrictions on the levels of any of the factors. We propose what we call a cylindrical design in which the levels of some factors are restricted while the other factors' levels need not be. Assuming the use of a second-order model, we give the general form for the model matrix X of such a design and give a closed form for the determinant of the X 0X matrix as well as its inverse. We use the results for the determinant and inverse of X 0X to compare designs using the alphabetic design optimality criteria. D-efficiencies, A-efficiencies, G-efficiencies, and IV-efficiencies for CCDs will be compared with those of the cylindrical design. Graphical assessment of the maximum spherical prediction variance will also be done. It will be shown that the cylindrical design is an excellent alternative when some but not all factors have restricted levels.

▼ Le procédé de flottation est une technique de
séparation de minerais basée sur la différence d’hydrophobicité des
espèces minérales introduites dans des cellules dans le but de
séparer les espèces minérales en fonction de ce critère. L’étude de
la mouillabilité d’une surface de minerai devient alors un concept
intéressant dans une optique d’optimisation de procédé. Les
technologies standards qui permettent l’étude de ce facteur sont
souvent imprécises due à la morphologie, aux défauts de surface
ainsi qu’à la chimie variable des particules présentes au sein d’un
même échantillon. Ayant pour but d’évaluer ce paramètre et
permettant d’avoir des échantillons suffisants pour effectuer
différents tests chimiques et minéralogiques, un nouveau montage
basé sur la flottation de surface a été développé. Des tests
comparatifs entre des technologies standards de flottation de
laboratoire ainsi que la flottation de surface ont été réalisés en
utilisant une matrice minérale composée de graphite et de quartz,
dans le but de comparer leur efficacité de séparation. Les
différents tests montrent, pour la flottation de surface, une
séparation sélective similaire à celle obtenue en cellule Denver en
plus d’être plus reproductible. Ensuite, des tests de flottation de
surface avec de la sphalérite et des moussants confirment la
compatibilité du montage avec des échantillons de minerais
complexes et exposent les changements de la flottabilité des
particules causés par la présence de surfactants. Un modèle par
régression logistique sur la minéralogie des échantillons démontre
une influence significative de la part des agents moussants sur la
probabilité qu’une particule flotte ou au contraire coule. Le
montage de flottation de surface est donc un outil de
caractérisation robuste et polyvalent pour l’analyse de la
mouillabilité d’un échantillon en reproduisant, de façon isolée,
l’étape de collision entre une bulle d’air et une
particule.
The flotation process is a separation technique
based on the wettability difference of minerals’ surface introduced
in the flotation cell to concentrate different mineral species
according to this criterion. In the optics of optimizing the
process, studying the wettability property of a mineral surface
becomes interesting. The standard technologies used to assess this
parameter are sometimes inaccurate for complex minerals due to
their irregular morphology, their surface defects and their
surface’s chemical heterogeneity which can bias the results. To
study the wettability of mineral samples, a new surface flotation
apparatus has been developed keeping in mind the necessity of
obtaining a sufficient amount of separated minerals in both the
overflow and underflow allowing chemical and mineralogical
analyses. Comparative tests have been conducted with the new
surface flotation design and two standard laboratory flotation
methods using a mineral matrix composed of graphite and quartz to
compare their separation efficiency. The results proved that the
new design of the surface flotation generates a…

▼ Manufacturing processes may significantly affect the quality of resultant surfaces and structural integrity of the metal end products. Controlling manufacturing process induced changes to the product’s surface integrity may improve the fatigue life and overall reliability of the end product. The goal of this study is to model the phenomena that result in microstructural alterations and improve the surface integrity of the manufactured parts by utilizing physics-based process simulations and other computational methods. Two different (both conventional and advanced) manufacturing processes; i.e. machining of Titanium and Nickel-based alloys and selective laser melting of Nickel-based powder alloys are studied. 3D Finite Element (FE) process simulations are developed and experimental data that validates these process simulation models are generated to compare against predictions. Computational process modeling and optimization have been performed for machining induced microstructure that includes; i) predicting recrystallization and grain size using FE simulations and the Johnson-Mehl-Avrami-Kolmogorov (JMAK) model, ii) predicting microhardness using non-linear regression models and the Random Forests method, and iii) multi-objective machining optimization for minimizing microstructural changes. Experimental analysis and computational process modeling of selective laser melting have been also conducted including; i) microstructural analysis of grain sizes and growth directions using SEM imaging and machine learning algorithms, ii) analysis of thermal imaging for spattering, heating/cooling rates and meltpool size, iii) predicting thermal field, meltpool size, and growth directions via thermal gradients using 3D FE simulations, iv) predicting localized solidification using the Phase Field method. These computational process models and predictive models, once utilized by industry to optimize process parameters, have the ultimate potential to improve performance of products in their service life.

▼ The thesis presents the design and development of a novel, rotational micro mirror using Flexible Printed Circuit Boards (FPCB) for the applications in laser marking/engraving system. The use of the new material helps in reducing the overall cost of the laser scanning system when compared to other MEMS based scanners but with higher mirror surface quality. The device mainly caters to applications that require low powered laser (<1watt), small working area (< 20x20mm) and slow scanning speed (2 mm/sec). The scanner consists of two orthogonally positioned quasi static micromirrors which are driven by magnetic lorentz force. Based on the developed laser scanner, a complete laser marking/engraving system was developed which is capable of engraving materials such as leather, TPU smartphone cases, etc. Further, the thesis also addresses a new problem (drifting) associated with the polyimide material used as the substrate for FPCB actuators and a modified vector scanning methodology is proposed to overcome it.

▼ In 2009, David Bachman introduced the notions of topologically minimal surfaces and topological index to generalize classes of surfaces such as strongly irreducible and incompressible surfaces. Topologically minimal surfaces have been useful in problems that deal with stabilization, amalgamation, and isotopy of Heegaard splittings of 3-manifolds and bridge spheres for knots. In this thesis, we will introduce the theory of topologically minimal surfaces and study Heegaard splittings from this perspective. In particular, we prove that Heegaard surfaces of genus g > 1 for the 3-sphere are topologically minimal, which disproves the conjecture that the 3-sphere contains no topologically minimal surfaces.

▼ This thesis concerns the spectral theory of the Laplacian on Riemann
surfaces of finite type, with emphasis on the quotients of the upper half plane by congruence subgroups. In a first part we show, following Otal, that on a Riemann surface M of genus g with n punctures there are at most 2g [-] 2 + n eigenvalues [lamda] with [lamda] [LESS-THAN OR EQUAL TO] 1/4. In a second part, we focus on arithmetic
surfaces. This
subject is treated by Maass in a paper that is difficult to read. We work out some examples of his construction of Maass forms.

▼ Abstract: The development of alternative high-k gate dielectrics for future complementary metal-oxide-semiconductor (CMOS) devices is indispensable in achieving both low leakage current and small equivalent oxide thickness. The thermal stability of these dielectrics on Si or Ge is a crucial issue to integrate them into CMOS, because standard device fabrication requires high temperature annealing, i.e. a dopant activation process (> 900 °C for Si and > 400 °C for Ge). HfO2 is one of the best candidates because of its high dielectric constant and high conduction band offset. On the other hand the formation of metallic Hf-silicide or GeO2 during the annealing process for activation is one of the most serious problems for Si-CMOS or Ge-CMOS, respectively. This thesis reports the results of a systematic study on the thermal stability of the HfO2 ultrathin films grown on Si3N4/Si, (100) and (111)
surfaces, for different silicon nitride film thickness deposited by low energy nitrogen ion implantation technique. Also the thermal stability of HfO2 ultrathin films grown on Ge/Si(100) and Ge/Si(111)
surfaces were studied as a function of annealing temperature. From these studies it was possible (1) to determine the minimum thickness of Si3N4 buffer layer to stabilize the HfO2 film up to 950 °C on top of the silicon
surfaces and (2) to avoid the formation of GeO2 interlayer in the HfO2/Ge/Si(111) system probably because the crystallographic orientation of Si surface

▼ AFRIKAANSE OPSOMMING: Berekeninge met Density Functional Theory (DFT) is ’n nuttige tegniek om die dinamika
van molekules op potensiële energievlakke te verstaan. Beginnende met ’n
prototipe molekuul formaldimien, wat die kern vorm van die groter fotochromiese
molekuul dithizonatophenyl kwik (DPM), word die modellering van die molekuul
meer ingewikkeld tot laasgenoemde bestudeer kan word asook sy fotochromiese
afgeleides wat vervanging van elektronryk en elektronarm radikale by orto, meta en
para posisies van die phenyl ringe insluit. DFT berekeninge word met spektra van
Absorpsiespektroskopie met UV en sigbare lig asook tyd opgeloste spektra, verkry
dmv femtosekondespektroskopie, vergelyk. In pol^ere aprotiese, pol^ere protiese en
nie-pol^ere oplosmiddels, isomeriseer die molekuul om die C=N dubbelbinding. Daar
kan tussen die twee isomere onderskei word deur dat die een in oplossing in sy
grondtoestand blou en die ander een oranje voorkom. Die isomerisering is’n fotogeinduseerde
proses. Die optimering van die molekul^ere struktuur, absorpsiespektra,
oplosmiddel-afhanklikheid, en potensiële energievlak metings van die molekuul word
bestudeer. Die sterk/swak wisselwerking wat in pol^ere protiese/aprotiese oplosmiddels
verskyn word geopenbaar deur die hoe/lae absorpsie van die sekond^ere bande
van die molekules. Daar is gevind dat die absorpsiespektra van DPM bathochromies
in oplosmiddels met hoë diëlektriese konstantes is. Vir die potensiële energievlak
berekeninge van die grondtoestand word rigiede en ontspanne metodes gebruik waar
laasgenoemde met gebroke simmetrie berekeninge verkry word. Van alle metodes
wat vir berekeninge gebruik was, gee die B3LYP/CEP-31G metode die beste benadering
aan eksperimentele data. Alle berekeninge word gedoen met twee bekende
sagteware pakkette; Amsterdam Density Functional (ADF) en Gaussian, wat op twee
verskillende DFT metodes gebaseer is.
ENGLISH ABSTRACT: Density functional theory is a useful computational tool in the understanding of
molecular dynamics on potential energy surfaces. Starting with a prototype molecule
formaldimine, the photochromic molecule dithizonatophenylmercury II (DPM) and a
set of its photochromic derivatives, (involving substitutions of electron donating and
electron withdrawing substituents at ortho, meta and para positions of the dithizonato
phenyl rings), are studied through density functional calculation in comparison
with steady state absorption spectra obtained from UV-Visible and femto second
spectroscopy experiments. In polar aprotic, polar protic and non-polar solvents these
molecules isomerise around C=N double bond chromophore, from orange electronic
ground states to blue electronic ground states upon photo-excitation. We investigate
the structural optimisations, the absorption spectra, the solvent dependence and the
potential energy surface (PES) of these molecules. The strong (weak) interactions
exhibited by the polar protic (aprotic) solvents used are revealed through high (low)
absorbance in the…

▼ In an effort to understand the resuspension phenomena, interactions of spherical micro-meter particles (glass beads (GB) and Stainless steel (SS)) were investigated experimentally on different
surfaces (glass, ceramic, hardwood, metal and chemical agent resistant coated metal (CARC)). Particles were deposited on the lower surface of a 10 cm square wind tunnel by gravitational settling. Air flows were imposed from an open entrance at average velocities up to 16 m/s. Individual particle trajectories obtained by high-speed imaging reveal three different types of motion: rolling/bouncing, immediate liftoff and complex motion. Surface roughness significantly affects the particle initial motion prior to liftoff. The majority of particle trajectories from the glass substrate were parallel to the surface with complex motion, covering 25% of the total distance traveled in rolling/bouncing motion before liftoff. Hardwood substrates took the longest time for initial particle movement (t >1 s) causing a more rapid liftoff. The ceramic substrate showed the most rolling/bouncing motion, for 80% of the particles. Additionally, single layer detachment showed that the detachment percentage initially follow an exponentially increasing trend for a period of ~ 1 s, followed by a plateau phase for a period of 5 s. Changing velocity, substrate and particle size significantly affects GB particle detachment. Furthermore, detachment from the metal substrate was consistently higher than the CARC substrates. However, particle density is not a significant difference in the bigger particle size studied. Initial 3-D particle tracking showed that particles seem to travel in a constant angle to the left rather than going straight in the flow direction. A detachment mode model showed that the detachment by direct liftoff required a much higher speed than rolling motion with a minimum of 14 m/s for both GB70 and SS70 on glass and metal surface, and the velocity increased to 21 m/s for the smaller particle. Incorporating the different types of particle motion prior to liftoff into resuspension models, and how their relative contributions change with different particle and substrate materials, can potentially yield improved predictive capabilities.

▼ Studying the reactions at the
surfaces of natural solids is important for understanding and regulating a number of environmental processes, including concentration and distribution of contaminants and nutrients in Earth’s aqueous systems. Mineral
surfaces, specifically, control permeability and exchange of contaminants and nutrients in soils, in part through the reactions that take place on these
surfaces. In this work, organic acid probe molecules (such as trifluoroacetic acid, TFA) were used to determine the type of binding sites and the species binding to the
surfaces of environmentally relevant model solids, such as kaolinite (KGa-2, KGa-1b), gibbsite and fumed silica. These determinations of surface chemistries and “reactive surface area” (RSA) provide a more comprehensive description of how a material will behave in the environment. In this context, reactive surface area is a measurement of the surface sites or functional groups that directly participate in surface reactions. Therefore, RSA represents the quantity of material available for reaction in a particular system and under specific conditions.
Solid-state nuclear magnetic resonance (NMR) was used in this work for structural information about specific nuclei and their surrounding environments, thus enabling a determination of RSA binding sites and the species being bound to the
surfaces. Bloch-decay magic angle spinning (MAS) NMR experiments were used to study the bulk structures of the materials and to determine the coordination environments of NMR-active nuclei, such as fluorine (19F), within probe molecules. Attenuated Total Reflectance Infrared Fourier-transform (ATR-FTIR) spectroscopy was also used (by our collaborators at PSU) to help elucidate the RSA of the environmentally relevant solids used in this work.

▼ In this thesis, we study generalized complex structures on Kodaira surfaces, which are non-Kähler surfaces that admit holomorphic symplectic structures. We show, in particular, that the moduli space of even-type generalized complex structures on a Kodaira surface is smooth of complex dimension four. Furthermore, we give an explicit description of this moduli space using deformation theory. We also obtain a Global Torelli Theorem for Kodaira surfaces in the generalized setting, which is an analogue of Huybrechts' result for generalized K3 surfaces. Finally, we study generalized holomorphic bundles with respect to the even-type generalized complex structures previously obtained.

▼ La formation des biofilms dans le secteur alimentaire et hospitalier constitue une cause principale soit d’intoxications alimentaires, soit d’infections nosocomiales. Pour prévenir ces infections, les travaux de thèse ont concerné, dans un premier temps, l’étude de l’effet de la température de culture sur la prédiction théorique de l’adhésion bactérienne, de Pseudomonas aeruginosa et de Staphylococcus aureus, sur l’acier et le polycarbonate. Les résultats ont montré que l’historique écologique de la bactérie influence significativement les propriétés de la surface bactérienne et par conséquent l’adhésion cellulaires sur les supports abiotiques. Cependant, les modèles mathématiques étudiés ne semblent pas être adéquats pour prédire les données expérimentales. Dans un deuxième temps, un system statique de formation des biofilms a été mis au point. Ce système a permis d’étudier l’effet de la température de culture, le type de support et l’âge physiologique sur la résistance des biofilms aux désinfectants. La structure tridimensionnelle des biofilms, la production qualitative, et quantitative, de la matrice extracellulaire ont été étudiés pour comprendre les mécanismes de résistance des biofilms. De plus, le profil d’acides gras membranaires des bactéries structurées en biofilm a été caractérisé afin d’étudier les mécanismes de résistance des biofilms à l’échelle cellulaire. Les résultats montrent que la résistance des biofilms aux agents biocides dépend des conditions environnementales de la formation des biofilms. Les résultats montrent aussi que la matrice extracellulaire ne permet pas toujours d’expliquer la résistance des biofilms aux traitements biocides et que l’état physiologie des bactéries structurées en biofilm joue un rôle significatif dans cette résistance.
The biofilm formation in food and medical sectors represents a significant source of infections worldwide such as the foodborne and nosocomial ones. To prevent infections, the the first part of this PhD thesis has dealt with the effect of growth temperature of Pseudomonas aeruginosa, and Staphylococcus aureus, cells on the theoretical prediction of bacterial adhesion to stainless steel and polycarbonate. The results showed that the bacterial background influenced the surface properties of bacterial cells and therefore the bacterial adhesion to the two selected surfaces. However, the mathematical theories seem to be inadequate to predict the bacterial adhesion to abiotic surfaces. Thereafter, a static biofilm reactor was established. This system has served to study the effect of the growth temperature, surface type and incubation time on the biofilm resistance to disinfectants. In order to understand the mechanisms of biofilm resistance to disinfectants, the investigations were carried out at a microscopic and macroscopic level. In fact, the three-dimensional structure of biofilms was investigated under the conditions selected for this study. Moreover, qualitative and quantitative studies of the biofilm matrix were also realized. In addition, the…

▼ Injury has been defined as body feeling that something wrong was happening (Deretke Clayton, 1981). One important element in determining the causes of injuries and prevention is having proper understanding of causes and ways of preventing as well as rehabilitation techniques. The long distance training requires prolonged hard working on the other hand the existence of biomechanical imbalance, too much running on the hard
surfaces and training shoes contributes for injures in the bones, muscles, ligaments and joints in the acute and sever cases. The purpose was to find out and recommend the causes and prevention of injures in the long distance athletes. The area of the problems were scarcity of proper foot wear, absence of sport medicine professional, qualification of coaches, the training
surfaces, prolonged training habits of athletes, and proper warm up and cool down, and stretching for flexibility increments and site conditioning and strengthen the ligaments and joints. The research methods selected for this study is descriptive survey research since the aim of the study is to describe facts. The primary sources of the data for the study long distance track athletes, the clubs coaches’ club administrators and athletics professional as well as sport medicine physicians. And also the document analysis, IAAF coaching materials, important internet websites and j provided important constructive topic under study. Questionnaires, interview, document analysis, discussion and observation were used in generating information from the respondents. These points raised as problem should be improved and understood by all stalk holders involved in the issues directly and indirectly to resolve the long distance athletes’ injury in the course of training and races.

▼ Arquitetos, em colaboração com artistas plásticos, designers e especialistas de
computação gráfica, têm concebido propostas em que sistemas de multimédia digitais interativos
ocupam parte importante do espaço construído assumindo-se como elementos diferenciadores
da vivência do espaço. Para a conceção e concretização destes projetos são necessárias novas
competências e instrumentos de trabalho que requerem a adoção de estratégias de planeamento
e produção específicas.
O projeto desenvolvido ao longo da investigação aqui apresentada versa sobre a
presença de elementos de comunicação visual em espaços urbanos e públicos, nomeadamente
através de superfícies multimédia interativas.
O estudo e a aplicação de uma superfície interativa aplica-se ao Conservatório Nacional
de Música de Lisboa, cujo projeto de reabilitação e ampliação é desenvolvido na vertente prática
deste trabalho de projeto.
Estudaram-se abordagens e tecnologias utilizadas atualmente na conceção de superfícies
interativas assim como se analisaram diferentes casos de implementação e aplicação em áreas de
edifícios. A proposta apresentada propõe explorar as possibilidades de incorporar na arquitetura
superfícies digitais capazes de criar uma nova dinâmica no espaço físico através da exposição
de conteúdos visuais que interagem em tempo real a estímulos recebidos dos visitantes desse
espaço. Dado tratar-se de um espaço dedicado à música, é o som emitido pelas pessoas e
instrumentos que será o estímulo exterior que despoleta reações da superfície interativa.
Para avaliar o carácter intuitivo e a pertinência da proposta, foram realizados testes de satisfação
e usabilidade com os possíveis utilizadores: os alunos do Conservatório de Música de onde se
concluiu que este apreciaram a proposta afirmando que é percetível os efeitos de som/imagem
apresentados.

▼ The simulation of adsorption processes on a heterogeneous crystal surface is the main interest of this thesis. Two applications of this event have been developed with Kinetic Monte Carlo simulation. One is how to control the crystal growth by macromolecules and the other is how to measure the effective rate of interactions near a crystal surface. The first part of this thesis, considers the effective rate of catalytic conversion on a heterogeneous catalytic surface. We assume the crystal surface has two types of active site, one is neutral and the other one is highly active. We compared our result from simulation with the analytical method that is given by the homogenization theory. Our result revealed the importance of patterns of surface energies and the size of them on reaction rate.
In the second project we consider the adsorption of a homopolymer chain on a crystal surface with two types of surface energies in order to limit the growth of one site and let the other sites grow more. We developed a new Kinetic Monte Carlo simulation method in this part, which was also applied to block copolymer chains that are more complex than a homo-polymer chain. Using this method four important phases of the polymer chains at high temperatures and also the free energies of the system across different patterns of active sites have been found. We tested different types of co-polymers to find the most differentiative block copolymer for controlling the crystal growth.

▼ Surface enhanced Raman spectroscopy (SERS) is undoubtedly a powerful tool as it allows one to
overcome the major disadvantage of Raman spectroscopy: the weakness of its signal. Enhancement
factors (EF) of up to 1010 make it even possible to detect single molecules. However, using
it as an analytical tool to make reproducible, quantitative measurements has so far been difficult
as the enhancement of the signal is "bought" at the expense of reproducibility: The larger the EF
the more the reproducibility of the substrate suffers. This has been dubbed informally the "SERS
uncertainty principle" by Natan [1]. While currently a lot of research effort is taking place at the
high-EF-side of the spectrum and ever more sophisticated SERS substrates are being explored, in
this thesis we would like to make a shift in paradigm and revisit SERS on flat metallic
surfaces,
which arguably constitute the simplest substrates available. To this end we will show their usefulness
in making quantitative measurements and how they are an ideal platform for a new hybrid
technique that combines reproducibility and extreme sensitivity with substantial EFs.
For making quantitativemeasurements two examples are explored in a systematic way: in the first
example (Chapter 2) the determination of an unknown, resonant Raman cross-section is demonstrated
on flat metallic films (possibly with some surface roughness) and confirmed with measurements
done on more commonly used SERS substrates. Here the quantitative measurement
is made possible by introducing a reference molecule as a standard and having statistics as our
main ally: even though we do not know the exact EF that the individual molecules experience on
the various substrates, we know that on average both, the unknown sample and the known reference,
experience the same. In the second example (Chapter 3) we use commercially available flat
films for which we verify experimentally that surface roughness is irrelevant. By themselves these
substrates yield no enhancement – in fact they even quench the Raman signal. Yet they allow us
to calculate and control the electric field on the surface which enables us to determine the orientation
of adsorbed molecules by using surface selection rules (SSR). While the first example is
mostly empirical, the second one allows us to test our theoretical understanding of plasmonic systems
with proper numerical calculations that are in excellent agreement with the observed data.
Finally, in Chapter 4, we use those flat films in a special configuration (called the Kretschmann
configuration) to excite Surface Plasmon-Polaritons (SPP). This not only allows us to combine the
spatial homogeneity of a flat surface with useful EFs easily predicted fromtheory but also to combine
the extreme sensitivity of surface plasmon resonance spectroscopy (SPRS) with the analytical
power of SERS.
It is not our intention to claim that the work presented here is the first attempt to do analytical
work with SERS. Rather the newmethods presented in this thesis will add new strategies and…

▼ Ces travaux de thèse ont porté sur l’étude de solutions originales pour limiter la biopollution dans des systèmes microfluidiques à base d'électromouillage (EWOD) couplés à un biocapteur à résonance de plasmons de surface (SPR). Deux approches complémentaires ont été étudiées. Dans un premier temps nous avons mis à profit la forte adsorption de protéines sur des nanofeuillets d'oxyde de graphène (GO): les caractérisations de mouillage de solutions contenant un mélange de GO et de protéines (albumine sérique bovine - BSA) ont permis de montrer que le GO maintenait en suspension les protéines en évitant leur adsorption sur la surface. Le résultat le plus remarquable obtenu concerne le déplacement par EWOD de BSA, à une concentration de 195ng/µL (pour 500ng/µL de GO), 30 fois plus que ce qu’il est possible de transporter sans GO. Nous avons montré que la présence des feuillets de GO n’altère pas l’activité enzymatique. Une autre solution a consisté à développer des surfaces superomniphobes (connues pour leur propriété d’auto-nettoyage) via un dépôt chimique de nanostructures d’oxyde de zinc (ZnO). Nous avons montré que certaines nanostructures de forme réentrante présentent des angles de contact supérieurs à 140°, des hystérésis inférieures à 20° pour des liquides de tensions de surface supérieures à 35mN/m. Pour finir, ces deux approches ont été validées pour l’application envisagée. L’interaction entre biomolécules et biodétecteur SPR a pu être validée (i) en contrôlant la désorption des protéines du GO par une solution basique, (ii) en réalisant des ouvertures dans les nanostructures de ZnO.
This work reports on the study of original strategies to limit biofouling in Electrowetting-on-Dielectric (EWOD) based microfluidic devices coupled with a Surface Plasmon Resonance (SPR) biosensor. Two complementary approaches have been investigated. In the first part, we take advantage of the high adsorption capacity of graphene oxide (GO) for biomolecules: the wetting properties of a mixed solution containing Bovin Serum Albumine (BSA) and GO show that GO keeps proteins in suspension inhibiting their adsorption on the surface. The most important result concerns the EWOD motion of BSA droplet with a concentration of 195ng/µL (with 500ng/µL of GO). In this case, the BSA concentration is 30 times higher than the BSA concentration which can be displaced without GO. We show also that the presence of GO in the droplet does not alter the enzymatic activity of horseradish peroxidase (HRP) after GO/HRP displacement. The other developed solution consists in the development of superomniphobic surfaces (known for their self-cleaning properties) via chemical deposition of zinc oxide (ZnO) nanostructures. The chemically functionalized ZnO nanostructures display contact angles higher than 140° and hysteresis lower than 20° for liquids of surface tensions higher than 35 mN/m. To conclude, these two approaches have been validated for the targeted application. Interaction between biomolecules and the SPR biosensor can be realized (i) by…
