16. Surface reactivity of metal nanoparticles : - importance of surface active agents and biomolecules from a transformation, mobility and toxicity perspective
Sammanfattning : Metallic nanoparticles possess unique properties due to their size and are widely used in e.g. consumer products. From this follows a need to identify and assess potential risks of human and environmental exposure. LÄS MER
17. Experimental studies of ash transformation processes in thermochemical conversion of P-rich biomass and sludge
Sammanfattning : The efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus present in manure and sewage sludge. LÄS MER
18. Laser transformation hardening of steel surfaces
Sammanfattning : The process of laser transformation hardening is a complex one to model in that there are a large number of parameters to account for. These include parameters of the process itself, e.g. beam intensity, intensity distribution, beam size, velocity of movement, degree of absorptivity, etc. LÄS MER
19. Multi-scale characterisation of pasta - Effects of raw materials on water absorption, water distribution, and microstructure
Sammanfattning : Pasta is a product with a long history, but is also still being developed today. Producers want to use new raw materials to make pasta more nutritious, less allergenic, and less dependent on durum wheat. All have in common that new raw materials shall not compromise the desired texture properties of cooked pasta such as the “al dente” feeling. LÄS MER
20. Local and global contaminants in Swedish waters : studies on PCBs, DDTs, 4,5,6-trichloroguaiacol and their transformation products in fish and sediments
Sammanfattning : This thesis is focused on studies on the environmental fate and methodological improvements for determination of the global contaminants, PCBs and DDTs, and locally discharged phenolics, e.g. 4,5,6-trichloroguaiacol (4,5,6-TCG), and their transformation products. LÄS MER
