Sonochemistry has experienced a large promotion in various fields concerned with the production of new nano-structured materials and improvement of their properties during recent years. However, it has encountered limitations in the case of the production of some nano-materials with specific morphology, size and properties. This book examines the application of sonochemistry for the synthesis of various nano-structured materials such as metals, metal carbides, metal oxides, chalcogenides and nanocomposites with unique properties.
