General Report: Sonochemistry and Sonoluminescence Conference

摘要

The presentation of data that demonstrate that a sonoluminescing bubble canproduce observable sonochemistry was also an important and interesting aspect of the ASI. Since sonochemistry has been difficult to study in the past because of the many bubbles that are typically formed within a cavitation field, the development of a system for studying SBSC is considered an important contribution to the field. An additional topic of much discussion was the physical mechanism(s) that lead to the light emission from SBSL. A strongly held theory is that imploding shock waves are developed within the gas during the later stages of bubble collapse. A second view is that asymmetrical collapses of the bubble can lead to liquid jets that penetrate the opposite bubble wall and generate light emission by fractoluminescence. These and many other theories were hotly debated and further calls were made to the experimentalists for additional data.
