Power ultrasound in electrochemistry: from versatile laboratory tool to engineering solution

The use of power ultrasound to promote industrial electrochemical processes, or sonoelectrochemistry, was first discovered over 70 years ago, but recently there has been a revived interest in this field. Sonoelectrochemistry is a technology that is safe, cost-effective, environmentally friendly and energy efficient compared to other conventional methods. The book contains chapters on the following topics, contributed from leading researchers in academia and industry: Use of electrochemistry as a tool to investigate Cavitation Bubble Dynamics Sonoelectroanalysis Sonoelectrochemistry in environmental applications Organic Sonoelectrosynthesis Sonoelectrodeposition Influence of ultrasound on corrosion kinetics and its application to corrosion tests Sonoelectropolymerisation Sonoelectrochemical production of nanomaterials Sonochemistry and Sonoelectrochemistry in hydrogen and fuel cell technologies INDICE: Preface List of Contributors Acknowledgements Introduction to Electrochemistry?
