  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. Glass Transition Dynamics in Soft Condensed Matter

    Detta är en avhandling från Chalmers University of Technology

    Författare :Johan Mattsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials science; glass transition; beta relaxation; excess wing; hydrogen bond; polymer films; Brillouin light scattering; polymer dynamics; confinement; cooperativity; IXS;

    Sammanfattning : Materials of very different character, ranging from polymers to metals can be made into glasses. The structural and dynamical properties of glass-forming materials are fundamentally different from those found in crystals. Hence, glassy materials exhibit unique characteristics, which make them suitable for a wide range of applications. LÄS MER

  3. 3. Dynamics of biological membranes and associated water

    Detta är en avhandling från Chalmers University of Technology

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kondenserade materiens fysik; Condensed matter physics; Biologisk fysik; Biological physics; lipid bilayers; purple membrane; glass transition; phase transition; long-range conductivity; polarisation; relaxation; diffusion; lipid dynamics; water dynamics; dielectric spectroscopy; DSC; QENS.;

    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

  4. 4. 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.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology; Teknik; 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

  5. 5. Glass-forming ternary blends: towards stable Polymer Solar Cells

    Detta är en avhandling från Chalmers University of Technology

    Författare :Amaia Diaz de Zerio Mendaza; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stability; glass formation.; ternary blends; fullerenes; organic photovoltaics;

    Sammanfattning : The globally increasing use of electricity goes hand in hand with climate change and the gradual depletion of fossil sources of fuel. To address these challenges renewable sources of energy are in high demand. LÄS MER
