  1. 1. Resistivity and the solid-to-liquid transition in high-temperature superconductors

    Detta är en avhandling från Stockholm : KTH

    Författare :Beatriz Espinosa Arronte; KTH.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high-temperature superconductors; vortex dynamics; vortex solid-to-liquid transition; critical scaling; glass transition; Bose glass; heavy-ion irradiation; YBCO; Tl2Ba2CaCu2O8 d; oxygen deficiency.; NATURAL SCIENCES Physics Condensed matter physics; NATURVETENSKAP Fysik Kondenserade materiens fysik;

    Sammanfattning : In high-temperature superconductors a large region of the magnetic phase diagram is occupied by a vortex phase that displays a number of exciting phenomena. At low temperatures, vortices form a truly superconducting solid phase which at high temperatures turns into a dissipative vortex liquid. LÄS MER

  2. 2. Dynamics of biological membranes and associated water

    Detta är en avhandling från Stockholm : KTH

    Författare :Peter Berntsen; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dielectric spectroscopy; phase transition; glass transition; DSC; lipid bilayers; lipid dynamics; water dynamics; purple membrane; diffusion; polarisation; QENS.; relaxation; long-range conductivity;

    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

  3. 3. Cohesive modelling of the temperature dependence of epoxy based adhesives in Mode I and Mode II loading

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Tomas Walander; Högskolan i Skövde.; Högskolan i Skövde.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology; Cohesive laws; Epoxy adhesive; Fracture energy; Peak stress; Temperature; Regression analyses; Shear modulus; Young’s modulus.;

    Sammanfattning : In this work, the influence of the temperature on the cohesive laws for two epoxy adhesives is studied at temperatures below the glass transition temperature for both Mode I and Mode II loading. Cohesive laws are measured experimentally under quasi-static loading conditions in the temperature range -30≤T≤80"C" . LÄS MER
