1. Infrared spectroscopy studies of adsorption and photochemistry on TiO2 surfaces : From single crystals to nanostructured materials
Sammanfattning : TiO2 based photocatalysis is a green nanotechnology that can be used for removal of pollutants from water and air, as well as making synthetic fuels from water and carbon dioxide. Said photocatalysis has received major research interests during the last decades. LÄS MER
2. Adsorption and reactions of sulfur dioxide on TiO2 surfaces : Fundamental studies on single crystals and nanoparticles
Sammanfattning : Titanium dioxide (TiO2) is a material that is well-known among researchers in environmental science but is perhaps less well-known by the general public. It is commonly used in white paint because of its ability to scatter visible light, and for this reason it is manufactured at a large industrial scale. LÄS MER
3. Micromechanics of oxides - From complex scales to single crystals
Sammanfattning : Protective oxide scales shield high temperature materials from corrosion, thus ensuring safety and long material life under adverse operating conditions. Cracking and spallation of such scales can lead to fatigue crack initiation and expose the material to further oxidation. LÄS MER
4. Tungstate Scintillators Growth, Structures and Properties
Sammanfattning : Tungstate crystals are well-known scintillators, which can be used as detector material for high-energy radiation and are often chosen as references in measurements on new luminescent materials. For measurements of excitation and relaxation properties, single crystals are desirable. LÄS MER
5. Ceramic Materials as Drug Delivery Systems
Sammanfattning : The aim of this thesis is to evaluate ceramic materials for drug delivery drugs applications. Three delivery routes were investigated; abuse-deterrent oral formulation, inhalation, and novel ceramic crystals with drug entrapped. A geopolymer matrix was developed in order to withstand non-medical abuse such as crushing, snorting, extraction etc. LÄS MER
