  1. 1. Crystallography in Four Dimensions : Methods and Applications

    Författare :Gunilla Carlsson; Janos Hajdu; Dieter Oesterhelt; Vilmos Fülöp; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; horseradish peroxidase; redox reactions; X-ray crystallography; haem catalysis; molecular movies; radiation damage; Molekylär biofysik; Molecular biophysics; Molekylär biofysik;

    Sammanfattning : The four-electron reduction of dioxygen to water is the most exothermic non-photochemical reaction available to biology. A detailed molecular description of this reaction is needed to understand oxygen-based redox processes. Horseradish peroxidase (HRP) is a haem-containing redox enzyme capable of catalysing the reduction of dioxygen to water. LÄS MER

  2. 2. Polarization portraits of lightharvesting antennas: from single molecule spectroscopy to imaging

    Författare :Rafael Camacho Dejay; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Energy transfer; Single molecule spectroscopy; Exciton; Fluorescence microscopy; Fluorescence polarization; Light-harvesting; Chromophore; Conjugated Polymer; Photosynthesis;

    Sammanfattning : Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored.

  3. 3. Structure and Dynamics in Amphiphilic Bilayers: NMR and MD simulation Studies

    Författare :Tiago Ferreira; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Solid-state nuclear magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) simulations were employed to study molecular structure and dynamics in amphiphilic bilayers. This thesis reports on method development and practical applications to two types of bilayer systems: simple cell membrane models composed of phosphatidylcholine lipids and cholesterol; and liquid crystals composed of ethyleneoxide-based surfactants often used in technological applications and in fundamental studies of amphiphile self-assembly.

  4. 4. Genetik i fiktion

    Författare :Andreas Gunnarsson; Johan Fornäs; Jan-Erik Hagberg; Jenny Sundén; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Genetik i massmedia; Narration; Fiktion; Teknik och kultur; Vetenskap och kultur; Technology and culture; Teknik och kultur;

    Sammanfattning : This licentiate’s thesis is concerned with how genetics is depicted and used in fictional stories. From a perspective that combines science and technology studies with cultural studies, it analyses narratives that deal with, or contain images of, genetics and gene technology. LÄS MER
