Book Description
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Book Description
In the 1980’s sonochemistry was considered to be a rather restricted branch of chemistry mainly involving the ways in which ultrasound could improve synthetic procedures, predominantly in heterogeneous systems and particularly for organometallic reactions. This volume traces the evolution of sonochemistry from a century ago when the effects of acoustic cavitation were first reported almost as a scientific curiosity, through the 1980’s to the present. It describes the ways in which scientific interest grew rapidly during the 1990’s with the formation of the European Society of Sonochemistry in 1990 and the launch of a new journal Ultrasonics Sonochemistry in 1994. It also includes two chapters relating to the evolution of the subject as seen through the particular experiences of the authors Tim Mason and Mircea Vinatoru, both pioneers of sonochemistry. One chapter is devoted to the ultrasonically assisted extraction (UAE) of chemicals from plant material. This also illustrates the different ways in which sonochemical technologies can be applied in both batch and flow systems leading to the development of large-scale processing. The other chapter relating to environmental protection shows the wide range of applications of sonochemistry in this important field for both biological and chemical decontamination.

Book Description
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.

Book Description
Traditionally heat and light are thought as energy sources to drive a particular chemical reaction, but now ultrasound is a promising energy source for this purpose. The collapse of a bubble generates a wide range of high temperatures and pressures, and therefore, use of ultrasound has a considerable potential in chemical and allied sciences. Ultrasound-assisted reactions are green and economically viable alternatives to conventional techniques. This new volume presents a complete picture of ultrasound-assisted reactions and technologies that can be used in organic synthesis, polymer synthesis and degradation, nanomaterials, wastewater treatment, food ingredients and products, pharmaceutical applications, bioenergy applications, and more. This volume aims to shed light on the diversified applications of ultrasound and its significant role as a green chemical pathway. Sonochemistry deals with the effect of ultrasonic waves on chemical systems. It has green value because of non-hazardous acoustic radiation and is therefore duly recognized as a green chemistry by synthetic chemists as well as environmentalists. There is no direct interaction of ultrasound with molecular species, but the observed chemical and physical effects of ultrasound are due to the cavitational collapse, which produces drastic conditions of temperature and pressure locally. It induces the formation of various chemical species, which cannot be easily attained under conventional conditions. Sometimes, these species are responsible for driving towards an unusual reactivity in molecular entities. This book, Sonochemistry: An Emerging Green Technology, provides the complete development of sonochemistry, starting with an introduction and basic concepts of sonochemistry and proceeding on to different types of sonochemical reactions, instrumentation, use of ultrasound in driving particular chemical reactions, and its applications in various fields, such as polymer synthesis, decontamination of water and wastewater, preparation of nanomaterials, food technology, pharmaceutical sciences, etc. The book also briefly discusses some areas that utilize ultrasounds of different frequencies. These include food products and their processing; anaerobic digestion of waste; and medical applications such as ultrasonography, sonodynamic therapy, drug delivery, etc. Sonochemistry will be successfully used on an industrial scale in pharmaceutical drugs, polymers, nanomaterials, food technology, material science, biogas production, etc. in years to come and will be an established green chemical technology of the future.

Book Description
TEAN-LOUIS LUCHE A French poet of this eentury, Pierre Mae Orlan, wrote "Adventure does not exist, it is only in the mind of he who is pursuing it, and, as soon as it is at one's finger tips, it vanishes to come back to life, far away, in a different shape, at the frontiers of imagination". This sentence could be used to define the adventure that many sonochemists experienced. Most of them did not even suspect that the "laboratory trick" they were using was the first contact with a considerable amount of science. If a personal note is allowed here, it ean be interesting to mention the part played by chance in my involvement in sonochemistry. Almost 20 years ago, we had to perform an apparently simple Grignard reaetion with n-butylmagnesium bromide and geranial, but the results were repeatedly unsatisfactory. The one-pot Barbier technique was attempted, also without success. From my studies at the University, I imagined that the failure of the latter reaction could be caused by a common phenomenon known by solid state chemists as passivation, which in some cases can be overcome by ultrasonication. By chance, an ultrasonie bath was sitting on the next beneh, borrowed to clean some equipment. We clamped our reluctant reaction mixture into the bath, the reaction proceeded vigorously, and ... the adventure started. Without knowing anything about cavitation, high energies, ete., we had an illustration of Goethe's word "Am Anfang war die Tat" (at the Beginning was the Act).

Book Description
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.

Book Description
This book provides informative, useful, and stimulating reading on the topic of organic sonochemistry – the core of ultrasound-based applications. Given the increasing interest in new and improved technologies, allied to their green and sustainable character (not always a valid premise), there is a great attraction for organic chemists to apply these protocols in synthesis and process chemistry. Unfortunately, as with other enabling technologies, many researchers new to the field have received a simple and dishonest message: just switch on! Therefore a significant portion of sonochemical syntheses lack reproducibility (surprisingly cavitation control and/or ultrasonic parameters are omitted) and the actual role of sonication remains uncertain. While this book does not provide a detailed description of fundamentals, the introductory remarks highlight the importance of cavitational effects and their experimental control. It presents a number of concepts of sonochemical reactivity and empirical rules with pertinent examples, often from classical and recent literature. It then focuses on scenarios of current interest where organic chemistry, and synthesis in particular, may benefit from sonication in terms of both chemical and mechanical activation. The “sustainable corner” of this field is largely exemplified through concepts like atom economy, renewable sources, wasteless syntheses, and benign solvents as reaction media. This book is useful for both researchers and graduate students, especially those familiar with the field of sonochemistry and applications of ultrasound in general. However, it is also of interest to a broader audience as it discusses the fundamentals, techniques, and experimental skills necessary for scientists wishing to initiate the use of ultrasound in their domain of expertise.
