16. Catalytic Emission Abatement and Gas Separation
Sammanfattning : Air pollution is still today a major health problem. Emissions from mobile and stationary sources are regulated, but economical considerations limit the implementation of the most efficient abatement systems. To improve urban air quality, there is therefore a need to develop simple, durable and cost efficient emission control methods. LÄS MER
17. Preparation and characterisation of biodegradable microspheres for the delivery of bioactive compounds
Sammanfattning : The incorporation of bioactive compounds into biodegradable polymer microspheres has several advantages. Firstly, the drug substance is protected from physiological degradation. Secondly, using microspheres from polymers with different degradation mechanisms, it is possible to design different release profiles with desired release rates. LÄS MER
18. Low-Temperature Oxidation of CO and Volatile Organic Compounds over Supported Platinum Catalysts
Sammanfattning : The catalytic oxidation of carbon monoxide (CO) and volatile organic compounds (VOC) is important for the reduction of harmful emissions from both vehicles and from stationary sources. Both these applications suffer from poor catalytic efficiency at lower temperatures. LÄS MER
19. Cellulose in Quaternary Ammonium-based Solvents: Dissolution, Modification and Coagulation
Sammanfattning : Processing cellulose through dissolution and regeneration is essential for many applications, yet challenges are posed because it does not readily melt or dissolve in commonly used aqueous and organic solvents. Consequently, extensive efforts have been devoted to developing novel and efficient solvents for cellulose, as well as exploring new functionalization routes. LÄS MER
20. Experimental studies on acute health effects of acrolein and other aldehydes
Sammanfattning : Aldehydes are reactive and ubiquitous in indoor as well as outdoors and can give rise to significant health problems in humans, e.g. irritation of the eyes and toxic effects on the upper respiratory tract. This thesis focuses on the irritating and inflammatory properties of three commonly occurring aldehydes; acrolein, crotonaldehyde and hexanal. LÄS MER
