Event description

Description

University Collections invite you to join us for a Scientific Oration by Professor Greg Metha, Department of Chemistry, School of Physical Sciences, The University of Adelaide. Join us at 5.30pm for a 6pm start, concluding at 7pm.

This year’s Oration will be presented by Professor Greg Metha, who has spent more than 20 years using spectroscopy, the interaction between molecular matter and light, to investigate a range of molecular phenomena and discover new molecules. His study of the complex light-driven chemistry occurring in the atmosphere has increased our understanding of molecular dissociation and provided insight into the excited states of molecules. This research uses light sources from lasers to synchrotrons, in the microwave, infra-red, visible, ultra-violet and X-ray regions of the electromagnetic spectrum. His most recent work involves using light to drive chemical reactions to produce chemical fuels directly from sunlight.

This presentation will touch on:

How light and other types of electromagnetic radiation interact with molecules.

How we can detect molecules in the far reaches of outer space, as well as other planets, and use this to inform us about the composition and formation of the universe, and the development of life on earth.

How absorption of light by molecules in our atmosphere stops our planet from freezing, and why climate change is a consequence of rising carbon dioxide levels.

How we can capture solar energy to drive endothermic reactions such as the formation of hydrogen from water and hydrocarbon fuels from carbon dioxide.

Professor Metha will lead us through this fascinating chemistry perspective which will show an exciting and new way to see into the world around us.
