11. Platelet-activating factor and lysophospatidylcholine in oxidized low density lipoprotein-mediated immune activation
Sammanfattning : Inflammation is a risk factor for development of cardiovascular disease, as in addition to known risk factors such as hypertension, hyperlipidemia, smoking and diabetes. Patients with inflammatory diseases including SLE have an enhanced risk of cardiovascular disease. LÄS MER
12. Activation of retrovirus spikes for membrane fusion
Sammanfattning : Retroviruses are enveloped viruses that use reverse transcriptase to convert their RNA genome into DNA which is integrated into the host DNA. They enter into the cell by a membrane fusion process. In this the viral membrane fuses with that of the cell so that the internal capsid of the virus with the genome can be released into the cell cytoplasm. LÄS MER
13. Theoretical Investigations of C–O Activation in Biomass
Sammanfattning : This thesis focuses on using computational chemistry approaches to study how biobased molecules interact with both homo- and heterogeneous catalysts. The reaction mechanisms of such transformations have also been studied. LÄS MER
14. First principles studies of CO2 activation and reduction over indium oxide and copper surfaces
Sammanfattning : Catalytic recycling of carbon dioxide (CO2) to added-value chemicals, such as methanol (CH3OH), have been proposed as a possible path for sustainable production of fuel and chemicals, in addition to providing a route to mitigate anthropogenic carbon emissions. Several catalytic systems are known to be active for conversion of CO2 to methanol, Cu/ZnO/Al2O3 being the main industrial catalyst for the process. LÄS MER
15. Micro-reaction Mechanism Study of the Biomass Thermal Conversion Process using Density Functional Theory
Sammanfattning : Biomass, or bio-energy, is one of the most important alternative energies because of environmental concerns and the future shortage of fossil fuels. Multi-scaled bioenergy studies have been performed in the division of Energy and Furnace Technology, which included studies of macroscopic systems such as systems and reactors, modeling of computational fluid dynamics (CFD), and atomic/molecular level studies.
