The uses of ultrasound in chemistry are examined from a laboratory-oriented viewpoint in this text. The author analyzes the types of ultrasonic equipment available and describes the correct assembly of laboratory apparatus for particular tasks.

There is an increasing interest in the exploitation of power ultrasound in chemistry and processing (sonochemistry). This text was writtem as a result of the many requests from potential sonochemists for an introduction and guide to the practical aspects of the topic. Theory is kept to a minimum and it is suitable for both academic and industrial readership at all levels.

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.

The application of ultrasound waves to chemical reactions — sonochemistry — has huge potential for innovation in eco-friendly and eco-efficient chemistry. Sonochemistry: New Opportunities for Green Chemistry first introduces the basics of ultrasonic waves and the history of sonochemistry before moving on to look at acoustic cavitation and the estimation of ultrasonic parameters. After this comes a discussion of the equipment needed for experimentation with sonochemistry. Finally there is an in-depth look at green sonochemistry in different fields of research, covering concepts such as new combinations of ultrasound with ionic liquids, microwave irradiation, enzyme combination, and sono-assisted electrochemistry. In conclusion, distinguished sonochemists from around the world share their opinions on the green sonochemistry, and their predictions in the field.Undergraduate and graduate students in chemistry, and practitioners of ultrasonic technology will gain a unique insight into the opportunities and challenges facing sonochemistry today in its theoretical and practical implementation.

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.

I want to apply sonochemistry to a new reaction or processing method – what is the best approach? What types of sonochemistry equipment is available on the market and which is the best to choose? Can I scale up my reaction and if so, how do I do it, given that ultrasound is non-linear? - Fully updated third edition conveys the increasing growth in applications and equipment to power ultrasound - Provides detailed descriptions of the newest ultrasonic equipment and its applications, which offer a wide range of frequencies with more reproducible experimentation and a variety of scale-up systems - Demonstrates the practical laboratory uses of ultrasound technology for industrial scale performance - Includes useful exercises to familiarize readers with sonochemical operations

Despite the fact that chemical applications of ultrasound are now widely acknowledged, a detailed presentation of inorganic systems covering nano-particles, catalysis, aqueous chemistry of metallic solutions and their redox characteristics, both from a theoretical and experimental perspective has eluded researchers of this field. Theoretical and Experimental Sonochemistry Involving Inorganic Systems fills this gap and presents a concise and thorough review of this fascinating area of Sonochemistry in a single volume.

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.

This is the fifth volume of Advances in Sonochemistry the first having been published in 1990. The definition of sonochemistry has developed to include not only the ways in which ultrsound has been harnessed to effect chemistry but also its uses in material processing. Subjects included range from chemical dosimetry to ultrasound in microbiology to ultrasound in the extraction of plant materials and in leather technology.
