1. Development of Nanostructured Tungsten Based Composites for Energy Applications
Sammanfattning : Tungsten (W) based materials can be used in fusion reactors due to several advantages. Different fabrication routes can be applied to develop tungsten materials with intended microstructure and properties for specific application including nanostructured grades. LÄS MER
2. Bacteria-sulfide mineral interactions with reference to flotation and flocculation
Sammanfattning : Biological processes have been attracting attention in mineral processing industry due to their lower operating costs, environmental acceptability and flexibility in adaptation. Bio-hydrometallurgical methods to treat various sulfide and oxide ores have been developed during the years and these processes have been adopted by certain industries. LÄS MER
3. Cell-protein-material Interactions on Bioceramics and Model Surfaces
Sammanfattning : The objective of this thesis was to investigate and characterize the interaction between blood proteins and different surfaces with emphasis on protein adsorption to bioceramics and model surfaces. Special effort was made to monitor the spontaneous and selective adsorption of proteins from human plasma and to examine the orientation, conformation and functional behavior of single proteins after adsorption.

4. Symbolic and Material Boundaries : An archaeological genealogy of the Urus of Lake Poopó, Bolivia
Sammanfattning : The thesis focuses on Bolivian Indians who are assimilated into ethnic groups as one of many consequences of the colonial past. An understanding of the complexity of this construction draws from disciplines such as Anthropology, Archaeology, History, Sociology, in an effort to expose the power relations behind the construction.

5. Modelling and Characterisation of the Martensite Formation in Low Alloyed Carbon Steels
Sammanfattning : The current work contains experimental and theoretical work about the formation of martensite from the austenitic state of the steel Hardox 450. Simulation of rolling and subsequent quenching of martensitic steel plates requires a model that can account for previous deformation, current stresses and the temperature history, therefore dilatometry experiments were performed, with and without deformation.
