    Abstract : This thesis summarizes work using hard X-ray radiation on nanosecond and picosecond timescales. The focus is on the experimental part including detailed descriptions of setups for laser pumped - X-ray probe experiments. X-ray diffraction is sensitive to structural properties on the length scale of chemical bonds. READ MORE

  3. 3. Crystallography in Four Dimensions Methods and Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gunilla Carlsson; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; horseradish peroxidase; redox reactions; X-ray crystallography; haem catalysis; molecular movies; radiation damage; Molekylär biofysik; NATURAL SCIENCES Chemistry Molecular biophysics; NATURVETENSKAP Kemi Molekylär biofysik;

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Linda C Johansson; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Serial femtosecond crystallography; Lipidic sponge phase crystallization; Membrane protein crystallization; X-ray free-electron laser;

    Abstract : 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. READ MORE

  5. 5. Time-Resolved and High-Energy Synchrotron Radiation Crystallography using X-ray Area Detectors: Calibration and Applications

    University dissertation from Chalmers University of Technology

    Author : Olof Svensson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1996]
