While it is still a mystery of how a low-energy-density sound wave can concentrate enough energy in a small enough volume to cause the emission of light, research in acoustic cavitation and sonoluminescence has lead to plausible theories in which the source of light can be experimentally sustained. It has also lead to promising applications, such a

This book presents the latest research on fundamental aspects of acoustic bubbles, and in particular on various complementary ways to characterize them. It starts with the dynamics of a single bubble under ultrasound, and then addresses few-bubble systems and the formation and development of bubble structures, before briefly reviewing work on isolated bubbles in standing acoustic waves (bubble traps) and multibubble systems where translation and interaction of bubbles play a major role. Further, it explores the interaction of bubbles with objects, and highlights non-spherical bubble dynamics and the respective collapse geometries. It also discusses the important link between bubble dynamics and energy focusing in the bubble, leading to sonochemistry and sonoluminescence. The second chapter focuses on the emission of light by cavitation bubbles at collapse (sonoluminescence) and on the information that can be gained by sonoluminescence (SL) spectroscopy, e.g. the conditions reached inside the bubbles or the nature of the excited species formed. This chapter also includes a section on the use of SL intensity measurement under pulsed ultrasound as an indirect way to estimate bubble size and size distribution. Lastly, since one very important feature of cavitation systems is their sonochemical activity, the final chapter presents chemical characterizations, the care that should be taken in using them, and the possible visualization of chemical activity. It also explores the links between bubble dynamics, SL spectroscopy and sonochemical activity. This book provides a fundamental basis for other books in the Molecular Science: Ultrasound and Sonochemistry series that are more focused on applied aspects of sonochemistry. A basic knowledge of the characterization of cavitation bubbles is indispensable for the optimization of sonochemical processes, and as such the book is useful for specialists (researchers, engineers, PhD students etc.) working in the wide area of ultrasonic processing.

Sonochemistry is studied primarily by chemists and sonoluminescence mainly by physicists, but a single physical phenomenon - acoustic cavitation - unites the two areas. The physics of cavitation bubble collapse, is relatively well understood by acoustical physicists but remains practically unknown to the chemists. By contrast, the chemistry that gives rise to electromagnetic emissions and the acceleration of chemical reactions is familiar to chemists, but practically unknown to acoustical physicists. It is just this knowledge gap that the present volume addresses. The first section of the book addresses the fundamentals of cavitation, leading to a more extensive discussion of the fundamentals of cavitation bubble dynamics in section two. A section on single bubble sonoluminescence follows. The two following sections address the new scientific discipline of sonochemistry, and the volume concludes with a section giving detailed descriptions of the applications of sonochemistry. The mixture of tutorial lectures and detailed research articles means that the book can serve as an introduction as well as a comprehensive and detailed review of these two interesting and topical subjects.

First published by McGraw-Hill in 1989, this book provides a unified treatment of cavitation, a phenomenon which extends across the boundaries of many fields. The approach is wide-ranging and the aim is to give due consideration to the many aspects of cavitation in proportion to their importance. Particular attention is paid to the diverse situations in which cavitation occurs and to its practical applications./a

Sonoluminescence is defined as the light emitted when a liquid is irradiated with ultrasound. Sonoluminescence is observed during ultrasonic irradiation of chromium, iron, molybdenum, and tungsten carbonyl solutions. The observed spectral lines correspond to atomic emission from the metal atoms. The intensity of sonoluminescence from Cr(CO)$\sb6$ was studied as a function of dissolved gases to determine the effect of thermal conductivity and $\gamma$ (C$\sb{\rm p}$/C$\sb{\rm v}$) on cavitational conditions. As predicted by thermal theories of sonoluminescence, the intensity of excited-state chromium emission decreases with increasing thermal conductivity of the noble gas, and the intensity of sonoluminescence from silicone oil solutions of Cr(CO)$\sb6$ was found to decrease with decreasing 1/($\gamma-$1). The sonoluminescence linewidth from Cr(CO)$\sb6$ is much broader than the linewidth from a typical gas-phase hollow cathode lamp spectrum. By assuming collisional deactivation of chromium by argon and using the Heisenberg Uncertainty Principle, the effective lifetime of the emitting species (Cr$\sp\*$) before collisional deactivation was calculated to be 0.20 $\pm$ 0.02 picoseconds. From the lifetime, local fluid densities following cavitational collapse can be calculated using the equation: N$\sp{-1}$ = $2\tau\sigma\sb{12}\sp2$ ($2\pi$RT(m$\sb1$ + m$\sb2$)/(m$\sb1$m$\sb2$)) $\sp{1/2}$ where N is the density, $\tau$ is the lifetime, $\sigma\sb{12}\sp2$ is the cross-section of the colliding atoms, and T is the temperature of the cavitation event. The local fluid density during chromium atom emission was calculated to be 0.15 $\pm$ 0.01 g/cm$\sp3$. From the lifetime and density it is possible, by using the Virial Equation of State, to calculate the effective pressure in the region of the emitting chromium atoms.$$\rm P = RT\rho/m\ \lbrack 1 + B\sb{T}\rho/m + C\sb{T}\rho\sp2/m\sp2 + \...\rbrack$$Using this equation, the effective pressure during sonoluminescence in the region of the excited-state chromium atoms was calculated to be 1700 $\pm$ 110 atmospheres. This result represents the first experimental determination of the pressure of the cavitation event. Sonoluminescence from seawater was studied to determine the effect of organic particulate matter on the observed intensity. Sonoluminescence from saltwater is characterized by emission from excited-state sodium atoms. There was no difference in intensity within experimental error for saltwater samples which were taken from surface or deepwater or were filtered or unfiltered.

Sonochemistry and cavitation are rapidly increasing in importance in modern chemistry as a result of many significant achievements made in recent years. In this current and comprehensive text, the author clearly details and illustrates these developments as well as the fundamental concepts. Much attention is given to the fundamental problems, such as the general kinetics of sonochemical reactions: energetic yields; the principles of the cavitation diffusion theory; the place of acoustic energy among other physical methods of action on matter; and the new electrical theory of cavitation phenomena, sonochemical reactions and sonoluminescence initiation (the theory developed by Professor Margulis). Results of low-frequency acoustic fields investigations are also observed. Special attention is given to the influence of acoustic fields on chemical reactions in nonaqueous systems, catalytic processes and the initiation of oscillating reactions. This publication is designed to broaden the application of ultrasound in chemical technology and improve the efficiency of existing production processes. Its comprehensiveness makes it a practical handbook which will prove invaluable to a broad readership amongst chemistry, engineering and physics undergraduates, graduates, researchers, and industrialists working in the fields of sonochemistry, ultrasonic and chemical technology, high energy chemistry, acoustics and biology.

Sonochemistry and the Acoustic Bubble provides an introduction to the way ultrasound acts on bubbles in a liquid to cause bubbles to collapse violently, leading to localized 'hot spots' in the liquid with temperatures of 5000° celcius and under pressures of several hundred atmospheres. These extreme conditions produce events such as the emission of light, sonoluminescence, with a lifetime of less than a nanosecond, and free radicals that can initiate a host of varied chemical reactions (sonochemistry) in the liquid, all at room temperature. The physics and chemistry behind the phenomena are simply, but comprehensively presented. In addition, potential industrial and medical applications of acoustic cavitation and its chemical effects are described and reviewed. The book is suitable for graduate students working with ultrasound, and for potential chemists and chemical engineers wanting to understand the basics of how ultrasound acts in a liquid to cause chemical and physical effects. Experimental methods on acoustic cavitation and sonochemistry Helps users understand how to readily begin experiments in the field Provides an understanding of the physics behind the phenomenon Contains examples of (possible) industrial applications in chemical engineering and environmental technologies Presents the possibilities for adopting the action of acoustic cavitation with respect to industrial applications
