21. Polarization transfer solid-state NMR for studying soft matter: From surfactants to the stratum corneum
Sammanfattning : The work presented in this thesis is dedicated to theoretical development, experimental testing and application of polarization transfer solid-state nuclear magnetic resonance (PT ssNMR). PT ssNMR is an analytical tool which provides detailed information about molecular mobility in model or simple soft matter systems at the low water content regime, enabling the creation of phase diagrams.

22. Corrosion of ferritic stainless steels used in solid oxide fuel cells - Investigation of novel coatings in single- and dual-atmosphere conditions
Sammanfattning : Solid Oxide Fuel Cells (SOFCs) are systems that convert chemical energy into electrical energy. Their high electrical efficiency and clean emissions (when H2 is used as fuel) make them a strong candidate for replacing conventional conversion systems, such as combustion engines. LÄS MER
23. Preparation and long-term performance of poly(ethylene-co-butyl acrylate) nanocomposites and polyethylene
Sammanfattning : The current study discusses the preparation and long-term performance of polymer composites used for various purposes under different ageing conditions.The first part deals with the preparation and characterization of polymer nanocomposites based on poly(ethylene-co-butyl acrylate) (EBA–13 and EBA–28 with 13 and 28 wt % butyl acrylate, respectively) and 2–12 wt % (0.

24. 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.

25. Condensation irrigation : simulations of heat and mass transfer
Sammanfattning : There is a growing water demand in the world. Along with the deterioration of existing water supplies, the escalating world population leads to the assumption that two out of three people will lack sufficient freshwater by the year 2025. LÄS MER
