  5. 4. 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

  7. 5. X-ray scattering and spectroscopy of supercooled water and ice

    Författare :Jonas A. Sellberg; Anders Nilsson; Lars G. M. Pettersson; Thomas Loerting; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supercooled water; ice; x-ray scattering; x-ray spectroscopy; free-electron laser; kemisk fysik; Chemical Physics;

    Sammanfattning : This thesis presents experimental studies of water and ice at near-atmospheric pressures using intense x-rays only accessible at synchrotrons and free-electron lasers. In particular, it focuses on the deeply supercooled, metastable state and its implications on ice nucleation. LÄS MER
