  2. 1. Investigation of Water Mobility using Diffusion-Sensitive MRI: The Role of q-Space Imaging, High b-Values and Diffusion Time

    Author : Jimmy Lätt; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; kurtosis; high b-value; diffusion; diffusion time; NMR; q-space;

    Abstract : Nuclear magnetic resonance (NMR) diffusometry provides important information about molecular motion on a microscopic scale. The advantage of NMR diffusometry is its ability to characterise microstructures non-invasively. This has made the method important not only in chemistry, biochemistry and materials science, but also in medicine. READ MORE

  4. 2. Diffusion tensor magnetic resonance imaging of the brain : Tractography analysis with application in healthy individuals and patients

    Author : Johanna Mårtensson; Elna-Marie Larsson; Jimmy Lätt; Danielle van Westen; Tim Dyrby; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Diffusion Tensor Imaging; Tractography; white matter tracts; Radiology; Radiologi;

    Abstract : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. READ MORE

  5. 3. Synthesis and Characterization of Transition Metal Diborides

    Author : Jimmy Thörnberg; Johanna Rosén; Per Persson; Helmut Riedl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DCMS; HiPIMS; Titanium Diboride; Titanium Aluminum Diboride; Chromium Diboride; Microstructure; Hardness; Oxidation Resistance;

    Abstract : This thesis is devoted towards physical vapor deposition (PVD) of thin films of transition-metal (TM) diborides, focused on the material system TiBx, Ti1-xAlxB2-y and CrBx. The metal diborides are a large family of compounds with both metallic and ceramic properties, due to its bonding nature being a mix of covalent and ionic bonds. READ MORE
