"fluid mechanics" . " microfluidics" . . "The project deals with fluid mechanics phenomena in smart microfluidic systems driven by external electric fields. Experimental glass and plexiglass microfluidic chips with embedded microelectrodes will be fabricated. One liquid will be dispersed in another immiscible liquid in the form of regular droplets. Oil in water (O/W), water in oil (W/O), and leaky dielectric fluid in leaky dielectric fluid (L/L) droplets will be formed. The following experiments will be carried out. O/W and L/L droplets will be electrically charged, addressed, merged and separated above microelectrodes by means of electrokinetic phenomena. Faradaic interactions will be partially avoided with the use of either electric potential waves with low amplitudes or conductive separating membranes. Passive charging of W/O droplets due to the dissolution of base metals will be tested. Poisson-Nernst-Planck-Navier-Stokes mathematical models of the droplet handling will be developed. Effects of the Maxwell stress and Faradaic interactions on the behavior and addressing performance of the microsystems will be quantified."@en . "1"^^ . . .
