School of Chemistry, University of Melbourne

“Sonochemistry – how sound can produce free radicals and chemical reactions, and much more”

Mostly, sound can be considered as a benign undulation in pressure as it passes through a medium.  However when sound interacts with bubbles in a liquid it can cause the bubbles to undergo expansion, followed by violent collapse. This adiabatic collapse can lead to the creation of ‘hot spots’ in the liquid, with temperatures equivalent to those at the surface of the sun (~6,000 °C) and pressures (~1000 atmospheres) greater than those found at the deepest parts of the earth’s oceans. The talk will explore some of the consequences of sound created ‘hot spots’ and the chemistry they initiate. It will also briefly touch on the possibility of bringing about nuclear confinement fusion and the synthesis of amino acids from prebiotic atmospheric gases.

Franz is a former Associate Dean of Research and Industry at the University of Melbourne, Deputy Director of the ARC Special Research Centre, Particulate Fluids Processing Centre, and Program Leader of its Liquid-Liquid Systems research activities.   His research interests are in the area of colloid and surface chemistry, interfacial reaction dynamics and sonochemistry.  His research has received the H.G. Smith Memorial Medal from the Royal Australian Chemical Institute, and in 2005 he was elected as a Fellow of the Australian Academy of Science.
