'The first year has been extremely successful. The author was able to begin his studies immediately, without having to wait for equipment, etc. This report gives details on three projects that were initiated during the first year. The first project to be described involves an experiment to determine the basic mechanism for cavitation-chemistry, or sonochemistry, in particular the light-emission process: What is the fundamental mechanism for light emission from cavitating bubbles? There are many theories, but most fall into one of two camps. The first is that during the bubble collapse, the interior heats up quazi-adiabatically, and light emission is a result of an incandescence. The second camp claims that the light-emission process is electrical. During the bubble collapse, there is an electrical discharge that results in light emission. Chemical degradation optimization depends greatly on which mechanism is dominant. The authors proposed to look for an electrical signal that would be generated if discharges were involved.'
