1. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings
Sammanfattning : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. LÄS MER
2. Characterization of aerosol nanoparticles by transmission electron microscopy
Sammanfattning : [abstract missing].... LÄS MER
3. Char conversion kinetics and aerosol characterization in biomass gasification
Sammanfattning : Biomass gasification is a thermochemical conversion by partial oxidation at elevated temperature of solid biomass into a gaseous energy carrier. The product gas contains the major components CO, H2, CO2, CH4, as well as some tar and inorganic impurities and solid particles such as ash, bed material, soot and char. LÄS MER
4. The high Arctic summer aerosol : Size, chemical composition, morphology and evolution over the pack-ice
Sammanfattning : Aerosol particles, especially in the high Arctic are still not very well represented in climate models. Particle size and number concentrations are strongly under-predicted and temporal variations of aerosol composition and size are still not very well understood, mainly due to the sparsity of observations.

5. Aerosol Generated Core-shell Nanoparticles : Synthesis and Characterization
Sammanfattning : Aerosol technology is a promising platform to synthesize and study core-shellnanoparticles - a multi-elemental nanoparticle system where the core of one material is covered by a shell of another material. In this thesis, two distinctly separate strategies have been explored to synthesize core-shell nanoparticles by aerosol methods: physical vapor deposition (PVD) by evaporation, and surface segregation via thermal treatment.
