1. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation
Sammanfattning : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

2. Secondary Organic Aerosols: Composition, Gas-to-Particle Partitioning and Physical Properties
Sammanfattning : Atmospheric aerosols influence our climate and air quality. Aerosol particles in the atmosphere are transformed through many different physical and chemical reactions. A substantial fraction of the particles in the atmosphere are of secondary origin, formed as a result of gas to particle conversion. LÄS MER
3. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds
Sammanfattning : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. LÄS MER
4. Physical properties and processes of secondary organic aerosol and its constituents
Sammanfattning : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. LÄS MER
5. Information in use : Aspects of information quality in workflows
Sammanfattning : This thesis is founded on the global growth of the service sector and its significance for society as a whole and for the individual human being. In the last decade, technology has changed the way services are created, developed and delivered in remarkable ways. LÄS MER
