Topic: The Opal and Beyond
When: Wednesday, April 15, 2015 at 7:30 pm
Where: CGA Classroom, Lower Concourse, 55 Queen Street East, Toronto
Speaker: Geoffrey Ozin, University of Toronto
One of the founding fathers of nanochemistry, Geoffrey Ozin, will discuss the nature and creation of colour. Using the natural diffraction grating of opal as a model, Professor Ozin and his team have developed "a new class of active photonic crystal with the distinctive ability to electrically, mechanically and chemically tune colour from structure."
Professor Ozin will show how the spectacular "play of colour" of precious opal can now be instantly produced and infinitely varied at will.
Geoffrey A. Ozin received his B.Sc. degree in chemistry from Kings College, University of London in 1965, and his D. Phil. degree in inorganic chemistry from Oriel College, Oxford University in 1967, and was an ICI Fellow at the University of Southampton from 1967-69 before joining the University of Toronto in 1969 where he is currently a Full Professor of Chemistry. He has been named Government of Canada Research Chair in Materials Chemistry and is an Honorary Professorial Fellow at the Royal Institution of Great Britain and University College London and a Guest Professor at Karlsruhe Institute of Technology.
