  1. 1. Lifetime Measurements of Excited States in the Semi-Magic Nucleus 94Ru

    Författare :Aysegul Ertoprak; Bo Cederwall; Magdalena Zielinska; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear structure; lifetime measurements; doppler shift attenuation method; thick target; Fysik; Physics;

    Sammanfattning : Lifetimes of highly excited states in the semi-magic (N=50) nucleus 94Ru were deduced from an analysis of the Doppler broadened transition line shapes. Excited states in 94Ru were populated in the 58Ni(40Ca, 4p)94Ru∗ fusion-evaporation reaction at the Grand Accélérateur National d’Ions Lourds (GANIL) accelerator complex situated in Caen, France.

  3. 2. Thick and Thin Ti2AlC Coatings

    Författare :Jenny Frodelius; Lars Hultman; Per Eklund; Hans Högberg; Lars Nyborg; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This Thesis explores the deposition techniques of magnetron sputtering and high velocity oxy-fuel (HVOF) spraying for Ti2AlC as a promising high-temperature material. Magnetron sputtering aims at producing thin (≤1 μm) Ti2AlC films of high crystal quality for use as a model system in understanding the material’s basic properties. LÄS MER

  4. 3. On the role of penicillin-binding protein SpoVD in endospore cortex assembly

    Författare :Ewa Bukowska-Faniband; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sporulation; cortex; Bacillus subtilis; penicillin-binding proteins; SpoVD; peptidoglycan;

    Sammanfattning : Bacteria of the genera Bacillus and Clostridium can form endospores as a strategy to survive unfavourable environmental conditions. Endospore formation involves synthesis of cortex, a thick layer of modified peptidoglycan that surrounds the spore. LÄS MER

  5. 4. Magnetron Sputter Epitaxy of CrB2/TiB2 Diboride Superlattice Thin Films

    Författare :Samira Dorri; Jens Birch; Vassilios Kapaklis; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Artificial superlattices with their exceptional properties have been popular in a broad range of applications such as electronic, magnetic, optical, and hard coating. Another potential application for single crystal artificial superlattices is highly efficient interference neutron optics, owing to an ultimate interface width of just ±½ atomic layer. LÄS MER

  7. 5. Isotope-Selective Spectroscopy: Fast Timing R&D and fp-Shell Mirror Isomers

    Författare :Robert Hoischen; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mirror isomer; time of flight; plastic scintillator; fast timing; time resolution; Fysicumarkivet A:2011:Hoischen;

    Sammanfattning : This thesis highlights the research and development of a new plastic-scintillator detector for time-of-flight measurements in relativistic heavy-ion beam experiments. The detector makes possible the identification of different ion species on flight distances as short as a few meters. LÄS MER
