Physicists from Switzerland learn to fly and control the movement of the smallest drops and particles with the help of acoustic waves. An article by scientists appeared in the journal Physical Review Letters, and her a summary is provided on the American Physical society. As part of the work, scientists used several standing acoustic waves – oscillations whose maxima and minima remain motionless in space. With their help, scientists managed make water droplets spin around, flatten, and move in closed orbits in vertical planes. IN message emphasizes that there was no destruction drops themselves. Scientists say similar technologies can used for non-contact manipulation of liquid droplets and small particles. In particular, they note that their method will allow for laboratory experiments under microgravity. Now such experiments require space flights or on an airplane, or using special towers, like shot casting. Acoustic levitation has been actively studied since the middle. The 2000s. So, for example, there are use projects sound waves not heard by the human ear. Acoustic method levitation is more difficult, for example, the electromagnetic levitation method, however, it allows you to work with non-conductive objects.
