1. Thin films for indoor air monitoring : Measurements of Volatile Organic Compounds
Sammanfattning : Volatile organic compounds (VOCs) in the indoor air have adverse effects on the dwellers residing in a building or a vehicle. One of these effects is called sick building syndrome (SBS). LÄS MER
2. Volatile organic compounds from microorganisms : identification and health effects
Sammanfattning : Damp building materials are subjected to degradation processes due to moisture and also microbial growth, with both of these giving rise to emissions of volatile organic compounds (VOCs) that may contribute to indoor air health problems. The overall aim of this thesis was to investigate emissions of reactive and non-reactive VOCs from damp building materials and from the microorganisms growing on them, and also to investigate the possible health impact of these compounds.

3. From hydrothermal carbonization to blue hydrochars and activated carbons : Adsorption of volatile organic compounds and heavy metals
Sammanfattning : Hydrothermal carbonization of carbohydrate and biomass is a straightforward method for preparing hydrochars at low temperature. Hydrochars are more carbonized than their precursors. Hydrochars themselves are carbon precursors for preparing activated carbons. Activated carbons are porous materials that can be used for water and air purification. LÄS MER
4. Emissions of organic compounds from landfills
Sammanfattning : The presence of hazardous compounds in waste presents ahazard to the environment both in the short term and the longterm perspective. Landfills containing organic waste canassimilate certain levels of hazardous organic compounds sincethey offer a potential for retention and possibly degradationof organic constituents during events which occur in landfills.

5. Hyperconjugation in Group 14 Organic Compounds : Design and Property Investigations
Sammanfattning : Nowadays π-conjugated molecules are widely used as materials for devices in organic and molecular electronics. This is due to the ability of such molecules to conduct electricity. However, π-conjugation leads to molecular rigidness and associated lower solubility, which limits possible applications. LÄS MER
