1. Epitaxial thin films of group 4 transition metal diborides
Sammanfattning : Group 4 transition metal diboride films were deposited epitaxially onto different substrates, typically at 900 °C, using direct-current magnetron sputtering from compound targets of ZrB2, TiB2, and HfB2. Epitaxial ZrB2 has been deposited on Al2O3(0001), 4H-SiC(0001), and Si(100) describing the epitaxial relationships on Si(100) for the first time, where two relationships were observed from pole-figure analysis, namely A) in-plane: ZrB2[001] ∥ Si[110] and ZrB2[110] ∥ Si[110], out-of-plane: ZrB2(100) ∥ Si(100), and B) in-plane: ZrB2[11] ∥ Si[110] and the same rotated 90° around the 102 axis, out-of- plane: ZrB2(102) ∥ Si(100).

3. CO studies of Herbig-Haro regions
Sammanfattning : High resolution CO (J=1-0) observations of HH 7-11 in NGC 123? and the region around Lk Ha 224 in NGC 7129, using the 25m Millimeter Wave Telescope at Onsala, Sweden, have resulted in detailed maps. These dark cloud regions, forming stars of low to intermediate mass, show signs of shock excitation, identified as Herbig-Haro objects and H?0 masers. LÄS MER
4. Where stars are born : Kinematics and photometry of starburst and postburst galaxies
Sammanfattning : The understanding of the formation and evolution of galaxies will not be complete until we understand the physical processes that trigger and regulate starformation in them. This work is about star formation on several size scales. LÄS MER
5. Expression and purification of membrane proteins: Focus on the G-protein coupled receptor MC4r
Sammanfattning : Membrane proteins are crucial components of the cell and are involved in many biological processes. Recombinant overexpression systems together with different purification methods are necessary to obtain large amounts of purified receptor for biophysical and functional studies. LÄS MER
