1. Chemical reactions in ventilation systems : Ozonolysis of monoterpenes
Sammanfattning : Chemicals in indoor air, either emitted from a source or from a reaction, have been suggested to cause ill health in buildings. However, no clear correlations between exposure and health effects have been made. In this thesis we studied the reaction between monoterpenes, a group of biogenic unsaturated C10 hydrocarbons, and ozone. LÄS MER
2. Physical and Chemical Processes in the Formation of Biogenic secondary Organic Aerosols
Sammanfattning : Vegetation emits a vast number of biogenic volatile organic compounds (BVOC). In the atmosphere they are oxidised, predominantly by O3, OH radicals or NO3 radicals, depending e.g. on chemical structure. LÄS MER
3. Formation, ageing and thermal properties of secondary organic aerosol
Sammanfattning : In order to properly represent and predict the effects of aerosol in climate systems, an accurate description of their formation and properties is needed. This thesis describes work done to increase the knowledge of processes and properties of atmospherically relevant secondary organic aerosol (SOA) from both biogenic and anthropogenic origin. LÄS MER
4. Theoretical studies of response properties of organic molecules
Sammanfattning : In this thesis eight papers are presented. They represent development of theory and implementation technique in quantum chemistry, as well applications. The first two papers describe advances in geometry optimization techniques. LÄS MER
5. Development of Mild Methods for Selective Covalent Functionalization of Graphene
Sammanfattning : This thesis discusses methods for the comparatively mild covalent functionalization of graphene. Several graphene models were investigated: polycyclic aromatic hydrocarbons (PAHs), chemical vapor deposition (CVD)-graphene on SiO2/Si substrate, graphite foil, graphite flakes, kish graphite and highly oriented pyrolytic graphite.
