1. Modelling of molybdopterin-dependent enzymes
Sammanfattning : The thesis deals with models for molybdopterin-dependent enzymes. Several model systems containing molybdenum or tungsten have been prepared and characterised, and their reactivity with oxygen atom acceptors and donors have been investigated. LÄS MER
2. The Formation and Breakdown of Passive Film on Ni Alloys : in situ synchrotron studies
Sammanfattning : Corrosion results in huge annual costs and a large environmental footprint. The corrosion rate of some alloys can be made negligible by the presence of a spontaneously forming oxide film on the surface, a so-called passive film. Famous examples of alloys exhibiting passivity are stainless steels. LÄS MER
3. Photophysics of Perovskite Nano- and Microcrystals
Sammanfattning : The demand and consumption of energy is increasing dramatically all around the world. Broad adoption of fossil fuels has triggered an enormous threat to the environment. To ensure sustainability of our species and habitat, new solutions to fulfill the energy demand have to be found. LÄS MER
4. In-situ Study of the Growth, Composition and Morphology of III-V Semiconductor Nanowires
Sammanfattning : It is widely known that nanoparticle seeded growth of III-V semiconductor nanowires often occurs via the vapor-liquid-solid mechanism. However, conventional growth of nanowires is carried out in closed systems, where mostof the details and dynamics of the growth are impossible to follow. LÄS MER
5. NMR Self-Diffusion Studies and Stability Studies of Emulsions
Sammanfattning : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. LÄS MER
