• Gebundenes Buch

Produktbeschreibung

Sonoelectrochemistry is a safe, cost-effective, environmentally friendly and energy efficient technology Power Ultrasound in Electrochemistry demonstrates how sonoelectrochemistry offers a practical sound solution to many industrial processes, e.g. water and soil remediation, heavy metals removal, production of micro- and nano-sized pharmaceutical ingredients. Edited by a leading name in the field, this comprehensive reference is relevant for both academic researchers, and practitioners in industry.

---

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
