“…574 The observed intensification of mixing by magnetic nanoparticles envisages applications in microfluidics from the mixing process within a microdroplet 576 to local flows in the gaps of ferrofluidic seals and bearings. 577 In the case of a rotating Hele-Show cell the growth of instabilities is strongly influenced by the rotation speed and magnetic field strength, evidencing also the Coriolis effect on labyrinthine instabilities. 575 In the case of electroferrofluids-weakly charged superparamagnetic iron oxide nanoparticles in a nonpolar solvent-the application of an electric field induces the migration of the magnetic NPs to form concentration gradients.…”
