  1. 21. Simulations of thermoelectric transport in granularsuperconductors

    Författare :Andreas Andersson; Jack Lidmar; Vladimir Krasnov; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Supraledning;

    Sammanfattning : This thesis presents results from numerical simulations of the Nernst effect dueto phase fluctuations in models of two-dimensional granular superconductors. Inaddition other transport properties, such as thermal conductivity and electrical re-sistivity are calculated. LÄS MER

  3. 22. Calorimetry under extreme conditions

    Författare :Neha Kondedan; Andreas Rydh; Ali Elshaari; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocalorimetry; Diamond anvil cell; Specific heat; Thermometry; Quasicrystals; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : This licentiate thesis presents developments of nanocalorimetry systems tailored for use under extreme conditions such as high pressure, intense magnetic fields, and low temperature. Nanocalorimetry is a powerful approach to study strongly correlated systems like superconductors, heavy fermions, and quantum materials with non-trivial magnetic or electronic properties, materials with emergent magnetic orders, as well as quasicrystals.

  4. 23. Dynamics of Biomembranes and Rheological Properties of Living Cells

    Författare :Peter Berntsen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cell mechanics; lipid dynamics; cell rheology; biomembranes; water dynamics; relaxations; phospholipids; glass transition;

    Sammanfattning : An ingenious assembly of biomolecules and water constitute what we call biological tissue. The presence of water in this assembly is fundamental for the physiological processes and can make the difference between life and death. LÄS MER

  5. 24. Rolling bearing lubrication at low temperature

    Författare :Victoria Wikström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Problems connected with rolling bearings at low temperatures are high starting and running friction, concerns about the presence of a lubricating film and the degree of roller slip at low-temperature start-up. Also, questions have been raised whether the high shear stresses in a grease sheared at low temperature could cause thickener degradation. LÄS MER

  7. 25. Elementary Surface Processes on Graphite and Aluminium

    Författare :Lars Österlund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Molecular processes on solid surfaces are of fundamental and technological importance. This work focuses on various reactive processes on a carbon (graphite(0001)) surface, and on the initial oxygen interaction with an aluminium (Al(111)) surface. LÄS MER
