1. Hygroscopic Properties of Aerosols from Open-Air Burning and Controlled Combustion of Biomass
Abstract : The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor.

2. Methods to Generate Size- and Composition Controlled Aerosol Nanoparticles
Abstract : This thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. READ MORE

3. Characteristics of fresh and aged carbonaceous aerosol from anthropogenic combustion sources
Abstract : Emissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. READ MORE

4. Fine and Ultrafine Particles from Combustion Sources - Investigations with In-situ Techniques
Abstract : Fine airborne particles are associated with adverse health effects in the human population. The aim of this research was to develop and evaluate methods for in-situ characterisation of fine and ultrafine particles and to determine their deposition in the human airways. READ MORE

5. Formation of nanoparticles by laser-activated processes
Abstract : Due to the small dimensions, nanoparticles and materials consisting of nano-sized building blocks exhibit unique — mostly superior — properties, well differing from their bulk counterpart. Most of the novel properties of nanoparticles (and nanomaterials) are size-dependent, while the majority of the common gasphase methods used for generation of nanopowders result in different, usually wide, size-dispersions.
