  1. 1. Measuring Material Properties through Gradient Based NMR: Diffusion and Imaging

    Författare :Ingrid Åslund; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intracellular diffusion; homogeneous length-scale; material properties; emulsions; yeast suspensions; lamellar phase; NMR; self-diffusion; membrane permeability and bending rigidity;

    Sammanfattning : In this work new methods based Nuclear Magnetic Resonance (NMR) have been developed to measure different kinds of structural properties in soft materials. The advantage of using NMR as a technique to measure material properties is that it is non-destructive, which makes it possible to measure on the actual piece of material that will be used for the application.

  3. 2. Development of Novel Diffusion NMR Methods : Preclinical Applications in Colloidal Model Systems

    Författare :Stefanie Eriksson; Fysikalisk kemi; []
    Nyckelord :diffusion NMR; diffusion tensor; Microscopic anisotropy; q-MAS; exchange; liquid crystals; yeast cell suspensions;

    Sammanfattning : NMR is a powerful non-invasive technique utilizing radiofrequency and gradient pulses to manipulate the spinsof atomic nuclei. In particular, diffusion NMR uses strong magnetic field gradients to label the positions of spins allowing for the measurement of translational motion of molecules in liquids. LÄS MER

  4. 3. Biophysical modelling in diffusion MRI: The role of tissue microstructure and water exchange

    Författare :Markus Nilsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion; MRI; tissue microstructure; water exchange; Monte Carlo simulations; white matter;

    Sammanfattning : Diffusion MRI is widely used to study brain structure in vivo. While this technique is often applied to investigations of brain connectivity, it can also be used to infer specific information about the tissue microstructure; for example, to estimate the axon diameter. LÄS MER
