Full text

Abstract:

An extremely wide variety of self-organised nanostructured patterns can be produced by spin-casting solutions of colloidal nanoparticles onto solid substrates. This is an experimental regime that is extremely far from thermodynamic equilibrium, due to the rapidity with which the solvent evaporates. It is the dynamics of ﬂow and evaporation that lead to the formation of the complex structures that are observed by atomic force microscopy (AFM). The mechanisms involved in the formation of these patterns are not yet fully understood, largely because it is somewhat challenging to directly observe t

Abstract:

This thesis is concerned with modeling geometric patterns. Specifically, a clear and practical definition for regular patterns is proposed. Based on this definition, this thesis proposes the following modeling setting to describe the semantic transfer of a model between various forms of pattern regularity: (1) recognition or identification of patterns in digital models of 3D assemblies and scenes, (2) pattern regularization, (3) pattern modification and editing by varying the repetition parameters, and (4) establishing exceptions (designed irregularities) in regular patterns. In line with this

Abstract:

Colloidal nanoparticles exhibit unusual individual and collective behaviour, often associated with interesting electrical, optical or electromagnetic properties. Thiol-passivated colloidal gold nanoparticles possess in addition a self-organising property, which, when the particles are deposited on a substrate, yields a plethora of fascinating patterns. The conditions of formation of these patterns are investigated, in order to understand the principles of - and gain control over - non-equilibrium self-organisation following drop evaporation. The work presented in this thesis relies mostly on e

Abstract:

This work is centered on the study of self-organisation and pattern formation in a prototypical nanostructured system, namely colloidal nanoparticle assemblies. The particular system chosen for investigation, Au nanocrystals spin cast onto silicon substrates from a solvent, despite being chemically rather simple exhibits a rich variety of complex patterns. In the majority of experiments discussed in this thesis, far-from-equilibrium conditions are attained by a spin-casting process which drives rapid solvent evaporation. A systematic study was carried out to determine the various factors affec

Abstract:

Pollinator visitation patterns should affect pollination success and mating patterns in flowering species. In the orchid family, about one third of the species do not provide any reward for their pollinators. Pollination by deceit is typically associated with low fruit set but may increase the chance of cross-pollination since the pollinator should soon leave the individual plant when there is no reward in the flowers. This may be beneficial if self-fertilisation results in inbreeding depression. I studied the mating patterns of one rewarding and one deceptive orchid in two closely related gen

Estuaries are naturally stressed systems with a high degree of variability in their physical-chemical characteristics. The natural gradient of salinity, linked with other gradients (e.g. sediment type and dynamics, oxygen availability, temperature and current speed) are well documented as important factors in determining temporal and spatial variations in meiofauna communities. Among the estuarine biological components, meiobenthic communities are good indicators of environmental conditions and therefore changes in their density, diversity, structure and functioning indicate important alterati

Applications in paleontological research are far from being limited to taxonomic collection and identification. Nor is such research limited to working solely on fossil data. Actualistic paleontology is the study of modern or recent organisms and processes to better understand those of the past. The bulk of this body of research falls under the category of actualistic paleontology, and examines geochronological methods and error biases in dating biological specimens ranging in age from modern to thousands of years old. Although such methods are arguably not perfect, error rates of Â± a few

Abstract:

This dissertation describes the impact of defects on monolayer properties for self-assembled monolayers (SAMs) created by interfacial patterning methods. When forming a two-dimensional interfacial pattern with n-alkanethiols on gold, the desired electrochemical properties are those of a homogeneous, solution adsorbed monolayer. However, even well-ordered SAMs contain a small degree of defects, especially at domain boundaries where two nucleating domains converge. Patterning a surface creates user-defined domain boundaries within the monolayer, potentially having a significant impact on the pro

Abstract:

Gold (Au) implantation in silicon (Si) has been a topic of great interest from both fundamental and applied perspectives. Ion implantation is a versatile technique due to its ability to form surface-embedded nanoparticles that provide better adhesion. Also, being an integral part of the substrate lattice, the nanoclusters produced by ion implantation are free from impurities and their size distribution can be controlled by carefully optimizing the beam parameters. During our experiments to produce nanoclusters of Au on Si for use as seeds for the growth of nanowires, we stumbled across an unus

As top-down lithography reaches the length scale of a single macromolecule, the combination with the bottom-up synthesis of polymer brushes by surface-initiated polymerization becomes one main avenue to design new materials for nanotechnology. Recent developments in surface-initiated polymerizations are highlighted along with diverse strategies to create patterned polymer brushes on all length scales based on irradiation (photo- and interference lithography, electron-beam lithography), mechanic

Abstract:

Nous étudions les propriétés photoniques dans le plan de monocouches de nanostructures auto-organisées. L'objectif de cette l'étude est d'appliquer les nanostructures auto-organisées pour la réalisation de cavités à cristaux photoniques (CP), et de nouvelles sources de lumière organiques. Le premier chapitre présente les opales et les opales-inverse réalisées à partir de nanoparticules auto-organisées et leurs propriétés optiques. Dans une deuxième partie, sont introduits les cristaux photoniques, leur physique et les outils numériques pour les quantifier. Le deuxième chapitre se concentre sur

Abstract:

Late Iron Age and Early Roman Britain has often been homogenised by models that focus on the resistance/assimilation dichotomy during the period of transition. The main objective of this thesis is to examine the rural settlements of this period through the lens of Cultural Theory in order to tease out the more nuanced and diverse human landscape that the material suggests. This approach begins to develop new ways of thinking about the variability observed in rural settlement from the end of the Middle Iron Age (MIA) to the beginning of the 2nd century AD. The selected study area is the Upper a

Abstract:

Cette thèse traite d'une méthodologie de Reverse Engineering (RE) d'assemblages mécaniques à partir de données hétérogènes dans un contexte routinier. Cette activité consiste à partir d'un produit ou d'un assemblage, à récupérer la donnée numérique en partant de la donnée physique dans le but de reconstruire sa maquette numérique. Plusieurs techniques de numérisation peuvent être employées et permettent de générer des données de différents types (ex : nuage de points, photographies). Ces dernières sont utilisées comme données d'entrée à notre processus de RE et peuvent aussi être associées à

Abstract:

<p>Nanofabrication techniques were used to manufacture nanometer scale protein templates. The fabrication approach employs electron beam lithography (EBL) patterning on poly(ethylene glycol) (PEG) thiol (CH3O(CH2CH2O)17NHCO(CH2)2SH) self-assembled monolayers (SAM) on Au. The PEG SAM prevented protein surface adhesion and binding sites for protein were created in the SAM by EBL. Subsequent to EBL, the patterns in the PEG SAM were backfilled with 40-nm NeutrAvidin-coated fluorescent spheres (FluoSpheres). The spontaneous and directed immobilization of the spheres from a solution to the patterns

To be successful, no-take zones require continuous monitoring of the fish community to evaluate the response of marine ecosystems to anthropogenic impacts and environmental change. Obtaining an understanding of the patterns of species composition, abundance, and distribution, allows monitoring efforts to be focused, efficient, and properly interpreted. Baited remote underwater
