Argonne National Laboratory Introduces Touchless Evaporation Techniques
Elise Ying-Hei Ho — September 30, 2012 — Tech
Scientists at Argonne National Laboratory have found a way to manipulate sound waves to levitate certain medicines.
In Acoustic Levitation, we can see individual floating pellets of medicine and droplets of liquid floating in sequence while certain sound waves are being played. As shared on the Argonne National Laboratory's Web site, this levitation technique uses two acoustic levitators, one placed on top of the other to "generate sound waves at frequencies slightly above the audible range." By doing so, they create sound waves that interfere with each other, which consequently allow the droplets to levitate in between the two speakers. This technique, which was originally used by NASA to create microgravity, or freefall, situations is now used in order to evaporate medicinal solutions without touching it, and what better way to do that than to make them dance in mid air.
