    Abstract :       Bainitic steels have attracted great attentions in recent years due to their excellent combination of properties to accommodate a wide range of applications. A deep and comprehensive understanding of how bainite forms is required to better design the production process and optimize the properties of bainitic steels. READ MORE

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

    Author : Robert Bosman; Göteborgs universitet; []
    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. 3. Structural characterization of proteins to investigate their roles in diseases: Focus on MID & LTA4H

    Author : Mahmudul Hasan; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Moraxella IgD binding protein; adhesin; leukotriene A4 hydrolase; small angle x-ray scattering; crystallography; circular dichroism;

    Abstract : Protein molecules are responsible for many biological functions in cells. In order to fulfill their various biological roles, these chain-like molecules must fold into precise three-dimensional shapes. The knowledge of accurate molecular structures is a prerequisite for rational drug design and for structure based functional studies. READ MORE

  6. 4. Crystallization on the Mesoscale : Self-Assembly of Iron Oxide Nanocubes into Mesocrystals

    Author : Michael Agthe; Lennart Bergström; German Salazar-Alvarez; Tommy Nylander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; iron oxide nanocubes; mesocrystal; small angle X-ray scattering; video microscopy; QCM-D; Materials Chemistry; materialkemi;

    Abstract : Self-assembly of nanoparticles is a promising route to form complex, nanostructured materials with functional properties. Nanoparticle assemblies characterized by a crystallographic alignment of the nanoparticles on the atomic scale, i.e. mesocrystals, are commonly found in nature with outstanding functional and mechanical properties.

    Abstract : I avhandlingen undersöks växelverkan mellan det yttersta lagret på växters blad (cutikeln), aktiva substanser, och ämnen som tillsätts för att öka bekämpningsmedlens effekt, i detta fall vissa former av tensider. Barriären som hindrar upptag av främmande ämnen i växten sitter i cutikeln. READ MORE
