"The way how synthesis is carried out today compared to 30 years ago is quite different. It can be attributed not only to the technological advances but also to negative impact on the environment caused by hazardous waste and dirty energies. As an alternative, ultrasonics represents a versatile tool successfully tested to replace other traditional energy sources and enhanced by other green energy sources. Being one solid pillar of eco-friendly energy, it is expected that sonochemistry will become part of future synthesis"-- Provided by publisher.
