6. Dissolving the Rocks : Solubility Enhancement of Active Pharmaceutical Ingredients using Mesoporous Silica
Sammanfattning : Poor aqueous solubility is one of the greatest barriers for new drug candidates to enter toxicology studies, let alone clinical trials. This thesis focuses on contributing to solving this problem, evaluating the oral toxicity of mesoporous silica particles, and enhancing the apparent solubility and bioavailability of active pharmaceutical ingredients in vitro and in vivo using mesoporous silica particles.

7. Drift-Type Waves in Rotating Tokamak Plasma
Sammanfattning : The concept of energy production through the fusion of two light nuclei has been studied since the 1950’s. One of the major problems that fusion scientists have encountered is the confinement of the hot ionised gas, i.e. the plasma, in which the fusion process takes place. LÄS MER
8. Rock Mass Response to Coupled Mechanical Thermal Loading : Äspö Pillar Stability Experiment, Sweden
Sammanfattning : The geological disposal of nuclear waste, in underground openings and the long-term performance of these openings demand a detailed understanding of fundamental rock mechanics. A full scale field experiment: Äspö Pillar Stability Experiment was conducted at a depth of 450 m in sparsely fractured granitic rock to examine the rock mass response between two deposition holes.

9. Tearing mode dynamics in the presence of resonant magnetic perturbations
Sammanfattning : Magnetically confined fusion (MCF) plasmas are typically subject to several unstable modes. The growth of one mode can limit the plasma energy confinement and might cause a termination of the plasma. Externally applied resonant magnetic perturbations (RMPs) are used to control and to mitigate some of the unstable modes. LÄS MER
10. Structures and Properties of the Chiral Smectic C Liquid Crystal Phases Ferro- and Antiferroelectricity in Soft Matter
Sammanfattning : Liquid crystals constitute a form of soft matter possessing lower symmetry than isotropic liquids but higher symmetry than solid crystals. In smectic A and C liquid crystals, the rodlike molecules are arranged in layers and the medium has crystal order in one dimension and liquid order in the other two. LÄS MER
