  2. 6. Bone structure characterisation using neutron scattering techniques

    Author : Elin Törnquist; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanics; neutron tomography; x-ray tomography; small-angle neutron scattering SANS ; small-angle x-ray scattering SAXS ; Experimental mechanics; implant integration; tomography; nanoscale; microscale; mechanical properties;

    Abstract : Bones have unique mechanical properties that originate from their main constituents: mineral, in the form of hydroxyapatite (HAp) crystals, and collagen type-I. The stiffness of the HAp mineral combined with the flexibility of collagen, and their intricate hierarchical arrangement from the smallest individual building blocks to the organ level, result in a composite tissue with a remarkable ability to withstand complex loading scenarios.

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

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

    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

  5. 8. Multiscale X-ray Characterisation of Cellulose-based Solid Dispersions

    Author : Martina Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PXCT; WAXS; pharmaceutical formulations; multiscale characterisation; STXM; radiation damage; SAXS; X-ray imaging; solid dispersions; cellulose;

    Abstract : Cellulose-based solid dispersions are a promising formulation strategy for providing controlled drug release and dissolution enhancement of poorly soluble drugs. These dispersions can from structures on multiple length scales which can have both positive and negative effects on the functional properties of the formulation. READ MORE

  6. 9. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors

    Author : Naureen Ghafoor; Jens Birch; Gabriella Andesson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft X-rays; Multilayer Mirrors; X-ray microscope; Materials science; Teknisk materialvetenskap;

    Abstract : A part of the Ph.D. project focused on growth and characterization of metal multilayers is presented in this licentiate thesis. The main interest in carrying out this research is to develop highly reflective normal-incidence condenser mirrors for soft X-ray microscopy studies in the water window (λ=2. READ MORE

  7. 10. MYC and MexR interactions with DNA : a Small Angle Scattering perspective

    Author : Francesca Caporaletti; Maria Sunnerhagen; Björn Wallner; Anne Martel; Ann Terry; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Protein-DNA complexes govern transcription, that is, the cellular mechanism that converts the information stored in the DNA into proteins. These complexes need to be highly dynamic to respond to external factors that regulate their functions in agreement with what the cells need at that time. READ MORE
