11. Investigation of the behaviour of gaseous I2 and RuO4 in different atmospheres
Sammanfattning : During a severe accident several hazardous and radiotoxic fission products can be released and constitute a threat to the environment. Two of the most important fission products are iodine and ruthenium which will be accumulated after inhalation in the human body in the thyroid gland and in the respiratory organs, respectively.

12. Investigation of Ilmenite from Oxygen Carrier Aided Combustion: Sulfur Interactions and Recovery of Elements
Sammanfattning : Oxygen- Carrier- Aided Combustion (OCAC) is a promising technology for the combustion of solid heterogeneous fuels such as biomass and waste in fluidized-bed (FB) units. In OCAC the conventional bed material silica sand is replaced by an oxygen carrier (OC). Replacing the bed material with an OC has many advantages. LÄS MER
13. Removal of Micropollutants from Wastewater : evaluation of effect of upgrading ozonation to electro-peroxone
Sammanfattning : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. LÄS MER
14. Titania supported vanadium oxide catalysts in the NH3-SCR reaction: Effect of vanadium loading, promoters and aging
Sammanfattning : Emissions of nitrogen oxides (NOx) from combustion processes in mobile sources attract significant attention due to their role as a major source of atmospheric contamination, along with health risks and environmental issues. Since combustion processes in heavy-duty vehicles are expected to be used for a foreseeable future, many efforts have been invested in a suitable deNOx technology. LÄS MER
15. Food and Packaging Interactions Affecting Food Quality
Sammanfattning : Food and packaging interactions that may impair the food quality have been studied and methods to determine these interactions have been developed. An off-line supercritical fluid extraction method using carbon dioxide was developed and used to extract sorbed low molecular weight compounds from polymer films. LÄS MER
