Abstract:

Silicon and silicon-based materials have been investigated for the fabrication of electronic, optoelectronic, solar, and structural/mechanical devices. To enable the continuous use of silicon-based materials for next generation device applications, new and inexpensive ways of fabricating features of silicon, and silica-based materials are needed. This dissertation investigates: 1) novel techniques for the fabrication of silica and silicon nanofeatures with potential application in the electronics and optoelectronics industry; 2) new designs of photomodifiable material systems (resists) for mas

We now give an overview of the content of this thesis, which consists of two parts. In the first part we present some results concerning the derivation of asymptotic models for thin curved rods (see Chapters 2 and 3). The second part is devoted to the study of homogenization problems for composite materials (see Chapters 4 and 5) and for porous media (see Chapter 6).

The goal of this research project was to develop a modelling technique making it possible to simulate grain boundaries and inclusion-matrix material interfaces using numerical techniques. This is particularly of interest when investigating the effects of grain boundary sliding and decohesion of the material interfaces under hot deformation conditions. This can then be used to predict damage nucleation and growth at the grain boundaries applicable to both creep type damage and plasticity induced damage.

Abstract:

In the past two decades, phonon transport within nanoporous thin films has attracted enormous attention for their potential applications in thermoelectrics and thermal insulation. Various computational studies have been carried out to explain the thermal conductivity reduction within these thin films. Considering classical phonon size effects, the lattice thermal conductivity can be predicted assuming diffusive pore-edge scattering of phonons and bulk phonon mean free paths. Following this, detailed phonon transport can be simulated for a given porous structure to find the lattice thermal cond

This work provides evidence that channels in directionally solidified hypoeutectic Pb-Sn alloys nucleate at the dendrite tips. Using a finite-element simulator, distinctive 'convective signatures' are shown to exist for convectively unstable cases, where the instability of a system is shown to be largely a function of the thickness of an inverted density layer that exists ahead of the moving solidification front. With D the diffusion coefficient in the melt and V the solidification rate, the thickness of this layer, and therefore the stability of the systems studied, is shown to be a function

In 2015 the global fibre consumption was 96.7 million tonnes, which is an increase of 3.1% from the year before. Our high textile consumption has led to an increasing demand of raw materials and generation of textile waste. Only in Europe, a total amount of 4.3 million tonnes of apparel waste each year is sent to either incineration or landfills. Approximately 50% of the clothes we discard and donate are composed of cotton. In the future, the cotton production is predicted to stagnate since the world population is increasing and arable land to greater extent will be needed for food production.

Since the balance of linear momentum is written in terms of an integral equation that remains valid in the presence of discontinuities, the peridynamic theory is suitable for studying the material behavior in regions with singularities.

Abstract:

Ett av problemen som företag möter om de vill börja tillverka handskar är att det inte finns standarder kring mått eller konstruktion. Det finns en praxis på breddgradering som följer handens omkrets i tum, men ingenting i längd. Denna rapport undersöker olika längdgraderingar som används på den svenska marknaden. Genom att mäta och jämföra olika tillverkares handskar hittades tre olika längder på fingrar i storlek 8 och tre olika graderingar från dessa storlekar: 15 mm, 10 mm och 5 mm. Dessa graderingar delas lika över finger och handflata. Handskar i storlek 6-11 har sytts upp och provats av

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico<br>O objetivo deste trabalho foi realizar um estudo sistemÃtico de parÃmetros de soldagem TIG com alimentaÃÃo de arame frio para aplicaÃÃo de revestimento de ligas de nÃquel (UNS N06625, UNS N06686 e UNS N10276) em substratos de aÃo C-Mn considerando a anÃlise das caracterÃsticas geomÃtricas, econÃmicas e operacionais dos depÃsitos, de forma a adequar estes revestimentos para as indÃstrias do Setor de PetrÃleo e GÃs Natural. As soldagens foram realizadas utilizando um robÃ industrial e um alimentador automÃtico de arame fri

Abstract:

La durée de vie des porteurs minoritaires est l'un des principaux paramètres mesurés dans les semi-conducteurs et la décroissance de photoconductivité (PCD) l'une des méthodes les plus largement utilisées pour ce type de mesure. Aujourd'hui, grâce aux divers équipements automatisés, la mesure de durée de vie est devenue une caractérisation de routine qui permet de juger de la qualité d'un matériau dans tous les secteurs utilisant les semi-conducteurs. Cependant, l'utilisation de micro- et nano-matériaux dans l'industrie du photovoltaïque et de la microélectronique requière l'adaptation des tec

Abstract:

Kompozitní materiály se projevují komplexním způsobem porušování, které může být dále ovlivněno přítomností různých poruch plynoucích z výrobních processů nebo se vyskytujících v průběhu života součásti. Důkladné porozmění procesů porušování a jejich okolností je nezbytné pro navrhování kompozitních konstrukcí, jenž budou bezpečnější, trvanlivější a ekonomičtější. V první části disertační práce jsou popsány způsoby porušování kompozitů a uvedeny současné matematické metody pro analýzu a výpočet únosnosti. Dále jsou zde vyjmenovány hlavní druhy vad a stručně diskutován jejich vliv na vlastnosti
