6. Nanostructured Tungsten Materials by Chemical Methods
Abstract : Tungsten based-materials are used in many different technical fields, particularly in applications requiring good temperature and/or erosion resistance. Nanostructuring of tungsten alloys and composites has the potential to dramatically improve the materials’ properties, enhancing the performance in present applications or enabling totally new possibilities.

7. Experimental studies of materials migration in magnetic confinement fusion devices : Novel methods for measurement of macro particle migration, transport of atomic impurities and characterization of exposed surfaces
Abstract : During several decades of research and development in the field of Magnetically Confined Fusion (MCF) the preferred selection of materials for Plasma Facing Components (PFC) has changed repeatedly. Without doubt, endurance of the first wall will decide research availability and lifespan of the first International Thermonuclear Research Reactor (ITER). READ MORE

8. Impact of erosion and deposition processes on wall materials in tokamaks
Abstract : Understanding of material migration and control of fuel retention are essential for the safe operation of a reactor-class fusion machine. Work presented in the thesis focuses on erosion-deposition processes which are decisive for the formation and properties of co-deposited fuel-containing layers on plasma-facing and diagnostic components, and for the dust formation.

9. Material characterization for magnetically confined fusion : Surface analysis and method development
Abstract : The dream of abundant clean energy has brought scientists and laypeople alike to ponder the possibilities of nuclear fusion since it was established as the energy source of the stars in 1939. Starting from the mid-twentieth century, significant effort has been put into overcoming the technological challenges related to the construction of a power plant, but initial optimism has faded somewhat due to a notable absence of practical outcomes.

10. 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
