Makes the matter fly with sound waves

Researchers from Zurich have found a way to make matter and especially liquid droplets fly in the air thanks to sound waves and they can also control their movement.

This result is useful when applied to research processes that restrict contact with the surface of the material such as some biological and biological processes. Scientists can use this technique to mix small amounts of substances and liquids without causing chemical alterations due to contact with the material surface as conventional.

Researchers manipulate the rise of the toothpick by changing the parameters of the sound wave and its reflex waves.

Professor of thermodynamics Dimos Poulikakos, who led the study, said scientists have previously made flying matter fly in a gravitational state by using magnets, electric fields and Arsimet thrust. Liquid. However, it is difficult to make a drop of liquid fly up with a magnet.

According to the team, the maximum diameter of the material must be equal to half the wavelength of sound used. An object is flown when all the forces acting on it are in equilibrium.

Gravity pulls the liquid downward and a balance force acts on it in the opposite direction. This force is generated by sound waves. Its sound waves and reflective waves create thrust against gravity.

The team successfully tested with small drops of a few millimeters in diameter.
