A whispering gallery in a drop of water
Acoustic waves can be used to control, agitate and mix fluids with extreme precision. Researchers from the Institut d'électronique, de microélectronique et de nanotechnologie, the Matière et systèmes complexes laboratory and the Institut des nanosciences de Paris have explained how these waves can induce the formation of vortices on the scale of a drop of water.
