21. Bicyclic Ligands and Catalysts in Asymmetric Synthesis
Sammanfattning : Synthesis of compounds based on the structurally rigid bicyclo[2.2.2]octane and the dibenzobicyclo[3.3. LÄS MER
22. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia
Sammanfattning : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. LÄS MER
23. Drugs and polymers in dissolving solid dispersions : NMR imaging and spectroscopy
Sammanfattning : The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioavailability of the drug.

24. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands
Sammanfattning : This thesis concentrates on the development, synthesis and evaluation of supramolecular systems, assembled from its components by means of hydrogen bonding, using the self-complementary 2-pyridone motif. The thesis is divided in two parts. LÄS MER
25. Catalytic conversion of biomass-derived synthesis gas to liquid fuels
Sammanfattning : Climate change is one of the biggest global threats of the 21st century. Fossil fuels constitute by far the most important energy source for transportation and the different governments are starting to take action to promote the use of cleaner fuels. LÄS MER
