In collaboration with European and American collaborators, major advances have been made in the technology, particularly as it applies to synthetic chemistry, materials science, and natural product isolation. Successful technological transfer of these developments is being realized through the efforts of several universities and allied companies, such as the Universities of Leeds, Nottingham, Bradford, Surrey, and Liverpool. Several key areas of application related to agricultural interests are an alternative method for degreasing animal hides, essential oil and nutraceutical extraction, production of ultra fine particles for improved dissolution in liquids, and low solvent coatings application. The described efforts are part of a "green" technology initiative spearheaded by such organizations as the Green Chemistry Network at the University of York in the United Kingdom. Such critical fluid technology is incorporated under such an initiative through the use of carbon dioxide and water as processing agents. |
