  1. 6. Characterization of injection molded polymers – from conventional to wood-based thermoplastics

    Författare :Linnea Björn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAXS; WAXS; melt processing; injection molding; Hierarchical Materials; Polyethylene; Dialcohol cellulose;

    Sammanfattning : The success of polymers products is associated with the melt processability, which allows to create products with complex shapes at a low cost. One of the most widely used processing techniques utilizing melt processability is injection molding, where a polymer is heated until it flows into a mold under pressure. LÄS MER

  3. 7. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin

    Författare :Robert Bosman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rhodopsin; SRII; SRII-HtrII; Time-resolved crystallography; Time-resolved wide angle x-ray scattering; TR-X; TR-WAXS; Serial crystallography;

    Sammanfattning : 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. LÄS MER

  4. 8. Synchrotron-based characterization of mechanobiological effects on the nanoscale in musculoskeletal tissues

    Författare :Isabella Silva Barreto; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoscale; microscale; mechanical properties; synchrotron; x-ray imaging; collagen; hydroxyapatite; biomechanics; experimental mechanics; x-ray tomography; small-angle x-ray scattering SAXS ; wide-angle x-ray scattering WAXS ; x-ray fluorescence XRF ; small-angle x-ray scattering tensor tomography SASTT ; Fourier-transform infrared spectroscopy FTIR ; polarized light microscopy PLM ; bone development; Achilles tendon; tendon healing;

    Sammanfattning : Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. LÄS MER

  5. 9. Mechanical behaviour of hardwoods : effects from cellular and cell wall structures

    Författare :Ingela Bjurhager; Lars Berglund; Ingo Burgert; Magnus Wålinder; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära;

    Sammanfattning : Syftet med den här avhandlingen var att undersöka mekaniska egenskaper hos olika arter av lövträd, och koppla egenskaperna till cell- och cellväggsstrukturen i materialet. Arterna som omfattades av undersökningen var Europeisk asp (Populus tremula), hybridasp (Populus tremula x Populus tremuloides) och ek (Quercus robur). LÄS MER

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

    Författare :Erik Malmerberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-resolved wide Angle X-ray Scattering; Retinylidene proteins; Rhodopsin; Bacteriorhodopsin; Proteorhodopsin;

    Sammanfattning : 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. LÄS MER
