immobilised enzymes for ethanol production
Prof. David McKenzie
Surface immobilised enzymes have potential advantages for a flow through
process for the synthesis of ethanol from cellulse wastes. Recent progress at the University of Sydney in the understanding of how some
enzymes in the cellulose family behave when immobilised on plasma treated
polymer surfaces will be described.
McKenzie has held a Personal Chair in Materials Physics since 1998. His
research focuses on selective surfaces and a sputtering technology for
depositing them. Their work resulted in a patented technology that has led to a
large renewable energy industry based on evacuated tubular solar collectors in Japan and more recently in China.
Professor McKenzie identified the form of amorphous carbon known as tetrahedral
amorphous carbon that contains a large fraction of diamond like bonds and has
many of the properties of diamond. It has found application as a wear resistant
coating and is used commercially in hard drives. Professor McKenzie has
developed materials for medical applications and has with his colleagues
developed new dosimeters for radiotherapy and new surfaces for biosensing and
medical diagnostics created from plasmas.
