11. Orientation of collectors adsorbed at the ZnS/solution interface
Sammanfattning : The separation and concentration of minerals by flotation is a well-known industrial process. In this process collectors are used to increase the hydrophobicity of the surfaces of the minerals. LÄS MER
12. Magnetodynamics in Spin Valves and Magnetic Tunnel Junctions with Perpendicular and Tilted Anisotropies
Sammanfattning : Spin-torque transfer (STT) effects have brought spintronics ever closer to practical electronic applications, such as MRAM and active broadband microwave spin-torque oscillator (STO), and have emerged as an increasingly attractive field of research in spin dynamics. Utilizing materials with perpendicular magnetic anisotropy (PMA) in such applications offers several great advantages such as low-current, low-field operation combined with high thermal stability.

13. Nanoscale structure forming processes : Metal thin films grown far-from-equilibrium
Sammanfattning : Thin film growth from the vapor phase has for a long time intrigued researchers endeavouring to unravel and understand atomistic surface processes that govern film formation. Their motivation has not been purely scientific, but also driven by numerous applications where this understanding is paramount to knowledge-based design of novel film materials with tailored properties.

14. Optical Characterization of Solar Collectors form Outdoor Measurements
Sammanfattning : Due to high installation costs and relatively low output, the active use of solar energy is limited. The output from a collector can be improved e.g. by using a selective absorber, AR-treated cover glass or transparent insulation. LÄS MER
15. Electronic Properties of Nanotubes
Sammanfattning : This thesis deals with various aspects of the electronic properties of carbon nanotubes and of generic nanotubes in magnetic fields. Carbon nanotubes are highly symmetric objects on the nanometer scale which show an interesting interplay of their geometry with electronic properties. LÄS MER
