Sonochemistry (8) The evolution of ultrasonic waves never stops. (The Future of Ultrasonic Cavitation Processing and Collaboration)
Ultrasonic waves are used to generate so-called spherical nebula cavities (micro vacuum nuclei) in liquids. The diameter of the cavity will be 10 mmΦ. That is, a vacuum ball with a diameter of 10 mm Φ is generated in about 1/40000th of a second and annihilated in 1/40000th of a second. It then moves at a speed of 100 m/sec.
At that time, positive and negative shock waves are generated, which are completely different from conventional ultrasonic waves. We are now able to control these cavities and provide a stable supply.
We hope that these shock waves will be effectively utilized and applied in fields other than ultrasonic cleaning, ultrasonic deburring, and ultrasonic barrel polishing.
In other words, we would like to effectively incorporate them into the world of physical and chemical reactions.
If we call these cavitation processing, this is a new processing technology in liquid. It is also a new technology for promoting reactions.
We are calling for broad collaboration on the application of these cavities. The following are some examples of cavities.
