1. Resistivity and the solid-to-liquid transition in high-temperature superconductors
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. Effect of water on the glass transition and properties of solid-state pharmaceutical formulations
Sammanfattning : The aim of this thesis was to increase our knowledge of the glassy state and the glass transition phenomenon and to evaluate the effect of water on the glassy state. To accomplish this, investigations were focused on the amorphous sucrose-water (paper I, II, III), trehalose-water (paper I), maltodextrin-water (paper I), and lysozyme-sucrose-water (paper IV) systems.

3. Glass Transition Dynamics in Soft Condensed Matter
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
4. Dynamics of biological membranes and associated water
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. Cohesive modelling of the temperature dependence of epoxy based adhesives in Mode I and Mode II loading
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
