- Induced-charge_electrokinetics abstract "Induced-charge Electrokinetics in physics are the electrically driven fluid flow and particle motion in a liquid electrolyte. Consider a metal particle (which is neutrally charged but electrically conducting) in contact with an aqueous solution in a chamber/channel. If different voltages apply to the end of this chamber/channel, electric field will generate in this chamber/channel. This applied electric field passes through this metal particle and causes the free charges inside the particle migrate under the skin of particle. As a result of this migration, the negative charges moves to the side which is close to the positive (or higher) voltage while the positive charges moves to the opposite side of the particle. These charges under the skin of conducting particle attract the counter-ions of the aqueous solution; thus, the electric double layer (EDL) forms around the particle. The EDL sing on the surface of the conducting particle changes from positive to negative and the distribution of the charges varies along the particle geometry. Due to these variations, the EDL is non-uniform and has different sings. Thus, the induced zeta potential around the particle, and consequently slip velocity on the surface of the particle, vary as a function of local electric field. Differences in magnitude and direction of slip velocity on the surface of the conducting particle effects the flow pattern around this particle and causes micro vortices. Yasaman Daghighi and Dongqing Li, for the first time, experimentally illustrated these induced vortices around a 1.2mm diameter carbon-steel sphere under the 40V/cm Direct Current (DC) external electric filed.Chenhui Peng et al. also experimentally showed the patterns of electro-osmotic flow around an Au sphere when Alternative Current (AC) is involved (E=10mV/μm, f=1 kHz).Electrokinetics here refers to a branch of science related to the motion and reaction of charged particles to the applied electric filed and its effects on its environment. It is sometimes referred as non-linear electrokinetic phenomena as well.".
