BME HDS - 5. Sonochemistry - the secrets of dancing bubbles

Описание к видео BME HDS - 5. Sonochemistry - the secrets of dancing bubbles

Can bubbles be useful? In this video, you can learn, how to use ultrasound to turn micron-sized bubbles into tiny chemical reactors. The technique became known in the scientific community as sonochemistry. During the process, we excite bubbles with ultrasonic irradiation, and this can be used to increase the speed of many chemical reactions by orders of magnitude. At the end of the video, we talk about the biggest challenges of sonochemistry.
