4. 23. Optical spectroscopy of turbid media: time-domain measurements and accelerated Monte Carlo modelling

   Författare :Erik Alerstam; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Optical spectroscopy is a versatile and powerful tool to probe translucent materials. In this work, the focus is on characterization of strongly scattering (turbid) materials by means of time-of-flight spectroscopy (TOFS). LÄS MER

5. 24. 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. 25. Magnetron sputtering of binary, ternary and multicomponent thin film borides and carbides

   Författare :Paulius Malinovskis; Ulf Jansson; Erik Lewin; Vladimir Vishnyakov; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Design of new thin film materials with improved properties and functionality is an important research field in materials science. In this thesis, I have used magnetron sputtering to deposit new thin film materials, which should combine high hardness and high ductility with other properties such as low friction or a good corrosion resistance.
