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.

These mechanical effects have not held the interest of synthetic chemists as much as the so-called true ones but nevertheless they are certainly important in areas such as processing.

Nowadays Ultrasound has been used for a variety of purposes there are research groups and industries with expertise in that includes areas as diverse as communication with a much wider range of activities that involve the uses of animals dog whistles , the detection of flaws in concrete ultrasound in electrochemistry, food technology, chem- buildings, the synthesis of fine chemicals and the treat- ical synthesis, materials extraction, nanotechnology, ment of disease.
Developments in the latter began in the s ics: this includes synthesis, catalysis and fundamental in the years preceding the Second World War when it studies of cavitation involving mainly academia.

A second is in the production and design of obtain funding in applied fields. It fits nicely into sev- nanoparticles linking sonochemistry with ultrasonic eral themes that have been identified in Framework 6 precipitation and the surface effects of cavitation. A below and it must be our job to find ways in which third example might be in chemical engineering where these can also be used to support pure research: the design of a sonochemical reactor would not seem to be connected with a study of sonoluminescence.
There are many more examples. In this review I will attempt to show that the many Let us take each of these themes and explore the po- and varied links that can be made across different ul- sition of sonochemistry within them. It is to be hoped trasonic disciplines will strengthen research in the gen- that by doing this sonochemistry can provide a hub eral area of sonochemistry. What is required is that all technology for industries of the future.
It is my belief of those interested in the promotion of the uses of ul- that within Europe we have some of the most innovative trasound, particularly power ultrasound, should become and influential scientists involved in sonochemistry and a little more outward looking i. Consequently this is a good route to fol- perceived but unreal barriers of their own disciplines.
