Diving with microparticles in acoustic fields
Alvaro Marin, Massimiliano Rossi, Rune Barnkob +5
Sound can move particles. A good example of this phenomenon is the Chladni plate, in which an acoustic wave is induced in a metallic plate and particles migrate to the nodes of the…
Acoustic radiation- and streaming-induced microparticle velocities determined by micro-PIV in an ultrasound symmetry plane
Rune Barnkob, Per Augustsson, Thomas Laurell +1
We present micro-PIV measurements of suspended microparticles of diameters from 0.6 um to 10 um undergoing acoustophoresis in an ultrasound symmetry plane in a microchannel. The mo…
Current-induced membrane discharge
M. B. Andersen, M. van Soestbergen, A. Mani +3
Possible mechanisms for over-limiting current (OLC) through aqueous ion-exchange membranes (exceeding diffusion limitation) have been debated for half a century. Flows consistent w…
