11. Studies of plasma-facing materials and macromolecules using scanning probe microscopy
Abstract : The main topic of this thesis is experimental analysis of material surfaces using scanning probe microscopies. These microscopes are used for characterization through high-resolution topographical imaging, but also for controlled modification of surfaces and molecules. READ MORE

12. Environmentally Degradable Polyethylene : Effects of Additives and Environment on the Degradation and Degradation products
Abstract : This thesis summarises and compares the influences ofdifferent additives (photosensitisers, pro-oxidants, abiodegradable filler) on blown low-density polyethylene (LDPE)films during photo- and thermal degradation with respect tochemical changes in the polymer matrices and identifieddegradation products. Additives studied were irondimethyldithiocarbamate (FeDMC), nickel dibutyldithocarbamate(NiDBC), carbon black, starch, a pro-oxidant that consisted ofmanganese stearate together with styrene butadiene rubber (SBR)or natural rubber (NR) and a master batch containing linearLDPE, starch and pro-oxidant.

13. Analysis of human epidermal Langerhans' cells and allergens with confocal laser scanning microscopy
Abstract : The aim of the thesis was to explore confocal laser scanning microscopy (CLSM) as a tool for 1) quantitative and 3-dimensional (3-D) analysis of the human antigen-presenting Langerhans' cell (LC) in epidermis and 2) for localization of allergens in yeast cells and in birch pollen. Epidermal LCs were investigated after occlusion with patch tests and in basal cell carcinoma (BCC) skin. READ MORE

14. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders
Abstract : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. READ MORE

15. Imperfections in Recycled Aluminium-Silicon Cast Alloys
Abstract : In striving to produce high quality cast components from recycled aluminium alloys,imperfections have to be considered, because recycled aluminium usually containsmore of it. However, there are great energy savings to be made by using recycledaluminium; as little as 5% of the energy needed for primary aluminium productionmay be required. READ MORE
