Abstract:

This thesis uses the techniques of atomic force microscope (AFM) and conductive AFM (C-AFM) to study the conduction properties of n-type GaN films. A total of 16 samples were examined and grouped according to their surface morphologies and conduction behaviors. The most common type of surface morpliology was that of Ga-rich samples having undulating "hillocks" with interspersed holes. Although most of the samples had this common morphology, their local conduction behaviors were not all similar. Local I-V spectra of the tip-sample Schottky contact could be grouped according to three major types

Abstract:

A combinação de algoritmos tem despertado interesse para melhorar o desempenho de filtros adaptativos. Esse método consiste em combinar linearmente as saídas de dois filtros operando em paralelo com passos de adaptação diferentes para se obter um filtro com conver- gência rápida e um erro quadrático médio em excesso (EMSE - excess mean squared error) reduzido. Nesse contexto, foi proposta a combinação afim de dois algoritmos LMS (least-mean square), cujo parâmetro de mistura não fica restrito ao intervalo [0, 1] e por isso é considerada como uma generalização da combinação convexa.

This thesis explores the experiences, encounters, responses and reactions to Islamophobia through a narrative study of forty female Pakistani and British students with a Pakistani heritage in universities across England.

Coronary artery disease (CAD) is caused by atherosclerosis, a chronic inflammatory response to modified lipoproteins. A key pathophysiological event is the lipid-induced transformation of macrophages into lipid-laden foam cells and their accumulation in atherosclerotic plaques. Heritable CAD risk is associated with common genetic variants at over 40 genomic loci; the underlying causal mechanisms remain largely unknown and could affect transcriptional regulation in foam cells. Epigenetic and gene expression changes were measured in primary human macrophages before and after exposure to atheroge

The project is concerned with the development of methods for the fabrication of magnetic sensor devices on Atomic Force Microscopy (AFM) probes and their characterization. The devices use the principle of the Hall effect (based on the Lorentz force) to sense the magnetic properties of a magnetized specimen. In the past Hall bar sensors have been fabricated using semimetals such as Bismuth, or using 2-d electron gas material based on heterojunctions in III-V material. The former probes are limited by low sensitivity. The latter are limited by the difficulty encountered when trying to integrate

Abstract:

O principal objetivo dessa dissertação é apresentar uma proposta para o ensino de função afim, desenvolvendo-se todas as atividades em turmas de primeiro ano do terceiro ciclo, o equivalente ao sétimo ano do Ensino Fundamental, a partir do emprego da Modelagem Matemática inserida em um cenário para investigação e compreendida como ambiente de aprendizagem. Pretende, também, verificar a pertinência de trabalhar tal conteúdo matemático com alunos dessa faixa etária. A turma investigada frequentava, na ocasião em que a proposta foi realizada, uma Escola de Ensino Fundamental da rede Municipal de

Abstract:

In this thesis for the first AFM has been employed for the high resolution imaging of a protein assembly. The DnaB-DnaG Helicase-Primase interaction in Bacillus is the key reaction that causes the switch from primase mode to polymerisation mode. This assembly was imaged using the AFM to a sub-molecular resolution revealing structural detail of the interaction. It is shown that the binding of the primase causes the structure of the helicase to switch from a hexamer to a trimer of dimers with one primase molecule bound to each dimer; also the existance of sub-populations with one and two primase

Abstract:

Avec l'intégration de circuits intégrés de plus en plus denses, le besoin d'outils de caractérisation adaptés à ces échelles se fait ressentir. Identifier et analyser les problèmes de fiabilité survenant dans ces structures à des dimensions inférieures à 100 nm demande la mise au point d'instruments innovants. Ce travail de thèse a consisté dans un premier temps à développer un appareil à champs proches sensible aux propriétés mécaniques de surface, et dans un second temps à analyser les résultats expérimentaux en s'appuyant sur des approches analytiques et/ou numériques.

Abstract:

Ein bedeutender Teilbereich der Nanomechanik beschäftigt sich mit der Erforschung kleiner, schwingender Systeme, welche aufgrund ihrer geringen Massen auf minimale Umgebungseinflüsse reagieren. Dies macht derartige nanoskalige Resonatoren zu äußerst empfindlichen Sensoren. Die fortschreitende Miniaturisierung nanomechanischer Systeme erfordert nun einerseits die Weiterentwicklung von Antriebs- und Detektionsmechanismen, andererseits spielt die Verbesserung der mechanischen Güte eine zentrale Rolle für die Erhöhung der Empfindlichkeit möglicher sensorischer Anwendungen. Hierfür ist die Unter

Abstract:

Replication of biological cells for the purpose of imaging and analysis under electron and scanning probe microscopy has facilitated the opportunity to study and examine some molecular processes and structures of living cells in a manner that were not possible before. The difficulties faced in direct cellular analysis when using and operating Atomic Force Microscopy (AFM) in situ for morphological studies of biological cells have led to the development of a novel method for biological cell studies based on nanoimprint lithography. The realization of the full potential of high resolution AFM im

Their potential to behave as real Josephson elements make them useful devices, with numerous applications. Powerful techniques, such as focused ion-beam and electron-beam lithography, were successfully used and are well understood in

Abstract:

The aim of this diploma thesis is to develop a linear positioning stage for Ultra High Vacuum (UHV) environment. Simple prototypes of the linear positioning stage were designed and incorporated as part of a multiaxis sample manipulator for a UHV Scanning Tunneling Microscopy / Atomic Force Microscopy (STM/AFM). Different types of position encoders and linear guideways are discussed. Implementation of the homodyne interferometer as an optimization tool for a slip-stick based linear stage is described. Scalar diffraction theory is used to model the diffraction grating optical position encoder be

Abstract:

This study describes the covalent and the electrostatic attachment of molecules, nano-particles, and proteins to patterned self-assembled monolayers. A scanning probe nanografting technique was employed to produce patterns of various sizes, down to 10 nm. Thus, we are able to demonstrate a degree of surface patterning which is an order of magnitude smaller than that used in the semiconductor industry. One efficient strategy for creating chemically specific nanostructures is to use the extraordinary catalytic properties of enzymes. However, as the dimension of a catalyst patch is reduced down t
