Research Statement
Researches on the supercritical fluid technology have been conducted in our group. The focusing areas include extraction, crystallization, adsorption and high-pressure phase equilibria. In particular, we are interested in the crystallization of pharmaceutical compounds using liquid and supercritical fluid antisolvents. As a results, we obtained many new findings on the nucleation procedures of drugs and polymer compounds. In addition, we perform experiments on the removal of VOCs using various types of clays.
