1. Synthesis of Nitrogen Heterocycles via 1,3-Dipolar Cycloadditions - Method Development and Applications
Abstract : Because of the diverse properties displayed by nitrogen heterocycles, they are one of the most commonly used structural elements in drug discovery. Due to this variation in properties, however, the chemistry and synthetic pathway to each heterocycle is unique. READ MORE

2. Co-firing animal waste, sludge, residue wood, peat and forest fuels in a 50MWth CFB boiler : ash transformation, availability and process improvements
Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE

3. Particulate airborne impurities : express analysis and health effects
Abstract : The cumulative effects of air pollutants are of principal concern in research on environmental protection in Sweden. Post-industrial society has imposed many limits on emitted air pollutants, yet the number of reports on the negative effects from them is increasing, largely due to human activity in the form of industrial emissions and increased traffic flows.

4. Atmospheric corrosion of zinc-aluminum and copper-based alloys in chloride-rich environments : Microstructure, corrosion initiation, patina evolution and metal release
Abstract : Fundamental understanding of atmospheric corrosion mechanisms requires an in-depth understanding on the dynamic interaction between corrosive constituents and metal/alloy surfaces. This doctoral study comprises field and laboratory investigations that assess atmospheric corrosion and metal release processes for two different groups of alloys exposed in chloride-rich environments.

5. Preparation and characterisation of perovskite and noble metal promoted oxide based catalysts
Abstract : This work concerns efforts to improve or replace noble-metal based catalysts used for car exhaust purification.Various oxide based catalysts have been prepared by impregnating washcoats such as (-Al2O3 and SiO2 with appropriate metal ions, and assemblies calcinated at elevated temperatures have been tested for catalytic activity in the oxidation of CO and C3H6 and reduction of NO.
