  1. 1. Signal Transduction in Photoreceptor Proteins Insights From Time-Resolved X-ray Solution Scattering

    University dissertation from Göteborg : Göteborgs universitet

    Author : Oskar Berntsson; Göteborgs universitet.; Gothenburg University.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; Photoreceptor; Time-resolved X-ray solution scattering; Protein dynamics; Phytochrome; Light-oxygen-voltage; Cryptochrome;

    Abstract : The ability to sense and react to different light conditions is of great importance for many organisms on the face of the earth. Specialized proteins known as photoreceptor proteins provide bacteria, plants and animals with this ability. READ MORE

  2. 2. Structural Studies Of Materials Using Time-Resolved X-ray Diffraction

    University dissertation from Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Author : Hengameh Allaf Navirian; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; structure of bulk crystal; x-ray diffraction; phase transition; mechanical properties; microscopy;

    Abstract : This work consisted of the application of X-ray diffraction methods to the study of ultrafast phenomena in various materials. Since the X-ray pulses generated from the bending magnet at the MAX II ring, where most of the experimental work was conducted, have a duration of the order of 300 ps, they can not be used directly as probe pulses in experiments where higher temporal resolution is required.

  3. 3. Conformational Dynamics of Rhodopsins Visualized by Time-resolved Wide Angle X-ray Scattering

    University dissertation from Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Author : Erik Malmerberg; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time-resolved wide Angle X-ray Scattering; Retinylidene proteins; Rhodopsin; Bacteriorhodopsin; Proteorhodopsin;

    Abstract : Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy to perform a variety of different biological functions. READ MORE

  4. 4. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin

    University dissertation from Göteborgs universitet

    Author : Robert Bosman; Göteborgs universitet.; Gothenburg University.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rhodopsin; SRII; SRII-HtrII; Time-resolved crystallography; Time-resolved wide angle x-ray scattering; TR-X; TR-WAXS; Serial crystallography;

    Abstract : Responding to different light conditions is an essential process for many organisms on earth. Unicellular organisms are no exception to this and mechanisms for controlling cellular movement must often be sensitive to light. READ MORE

  5. 5. Following nanoparticle self-assembly in real-time Small-angle X-ray scattering and quartz crystal microbalance study of self-assembling iron oxide nanocubes

    University dissertation from Göteborgs universitet

    Author : Martin Kapuscinski; Lennart Bergström; Niklas Hedin; Andrei Petukhov; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembly; mesocrystal; time-resolved; small-angle X-ray scattering; iron oxide nanocubes; QCM-D; materialkemi; Materials Chemistry;

    Abstract : Self-assembly of nanoparticles is a widely used technique to produce nanostructured materials with crystallographic coherence on the atomic scale, i.e. mesocrystals, which can display useful collective properties. This thesis focusses on the underlying mechanism and dynamics of mesocrystal formation by using real-time techniques. READ MORE
