  1. 1. Lipidic-sponge phase crystallisation and time-resolved Laue diffraction studies of bacterial photosynthetic reaction centres

    Författare :Annemarie Wöhri; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipidic-sponge phase crystallization reaction centre from Rhodobacter sphaeroides and Blastochloris viridis photosynthesis evolution time-resolved Laue diffraction;

    Sammanfattning : Photosynthesis is the procedure of light capture and converting it into a chemical energy source for the cell. The work-horse of this process are photosynthetic reaction centres, which capture photons with the help of their antenna complexes and use these photons to drive charge separation reactions, and ultimately chemiosmotic coupling.

  3. 2. Advances in Membrane Protein Structural Biology: Lipidic Sponge Phase Crystallization, Time-Resolved Laue Diffraction and Serial Femtosecond Crystallography

    Författare :Linda C Johansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Serial femtosecond crystallography; Lipidic sponge phase crystallization; Membrane protein crystallization; X-ray free-electron laser;

    Sammanfattning : Membrane proteins carry out many essential tasks in cells such as signaling and transport, or function as electron carriers in photosynthesis and cellular respiration. The aim of this thesis has been to develop new and improve existing techniques for elucidating the structure and function of membrane proteins. LÄS MER

  4. 3. Local structure of perovskite ferroelectric ceramics as revealed by 3D electron diffuse scattering : A walk in between the Bragg peaks

    Författare :Alexandra Neagu; Cheuk-Wai Tai; Gunnar Svensson; Kenji Kaneko; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron diffraction; Diffuse scattering; Local structural disorder; Perovskite; Ferroelectric ceramics; Transmission electron microscopy; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Local structural disorder in crystalline materials plays a crucial role in understanding their properties. The means to study structural disorder is diffuse scattering (DS). LÄS MER

  5. 4. Tin whiskers: experiments and modelling

    Författare :Johan Hektor; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tin whiskers; Intermetallics; Phase field models; X-Ray Diffraction;

    Sammanfattning : Tin whiskers are hair-like single crystals that spontaneously grow from tin-coated surfaces. Whiskers are commonly found in electronic components, where tin coatings are used in, e.g., soldering applications, and to protect components from corrosion. LÄS MER

  7. 5. Magnetic Ordering in Layered Magnets

    Författare :Moreno Marcellini; Björgvin Hjörvarsson; Roger C.C Ward; Uppsala universitet; []
    Nyckelord :Physics; Magnetic thin films and superlattices; Magnetic phase transitions; Polarized neutron reflectometry; Fysik;

    Sammanfattning : The preparation of layered magnets needs the knowledge of growth techniques which are focused on the growth of Fe/V(001) superlattices. Such films have been structurally investigated by X-rays reflectivity and diffraction. LÄS MER
