Subduction-zone magmatism is triggered by the addition of H(2)O-rich slab-derived components: aqueous fluid, hydrous partial melts, or supercritical fluids from the subducting slab. Geochemical analyses of island arc basalts suggest two slab-derived signatures of a melt and a fluid. These two liquids unite to a supercritical fluid under pressure and temperature conditions beyond a critical endp...

Trichlorocarbanilide has widely been used in cosmetics and household products, but the extremely low solubility of trichlorocarbanilide in water constrains the development of water-based products. In order to enhance the bioavailability, trichlorocarbanilide were micronized using supercritical fluid. Supercritical carbon dioxide was selected due to relatively low critical temperature and the ra...

The aim of this study was to enhance the apparent solubility and dissolution properties of flurbiprofen through inclusion complexation with cyclodextrins. Especially, the efficacy of supercritical fluid technology as a preparative technique for the preparation of flurbiprofen-methyl-β-cyclodextrin inclusion complexes was evaluated. The complexes were prepared by supercritical carbon dioxide pro...

Gentle alternatives to existing sterilization methods are called for by rapid advances in biomedical technologies. Supercritical fluid technologies have found applications in a wide range of areas and have been explored for use in the inactivation of medical contaminants. In particular, supercritical CO(2) is appealing for sterilization due to the ease at which the supercritical state is attain...

This thesis discusses particle production by supercritical antisolvent processing (SAS) techniques by looking the fundamentals and applications of the method with some case studies. The final aim of this work is however to consider the SAS particle production process feasibility. In the process studied the solid is dissolved in a conventional solvent and the solution is sprayed continuously thr...

The design and development of processes involving supercritical fluids depend on how easy the phase equilibrium can be accurately modelled and predicted. In the work described herein, the supercritical fluid-solid equilibrium has been considered. Modelling the fluid-solid equilibrium is associated with a number of drawbacks, even when it is possible to obtain the experimental solubility data fo...
