Ultrasonic Fabrication of Metallic Nanomaterials and Nanoalloys

This review demonstrates the potential of sonochemistry to become a valuable tool for nanotechnology through composite fabrication if the underlying complex processes are understood and controlled. We show that control of cavitation requires control of interfaces at the microsecond timescale, and a diversity of phenomena is observed at the cavitation interface using different surfactants. Concrete examples show that it is possible to prepare nonequilibrium mono- and multicomponent metallic nanostructures that possess properties considerably different from those of nanostructures prepared by conventional methods.
