Electroosmosis in homogeneously charged micro- and nanoscale random porous media has been numerically investigated using mesoscopic simulation methods which involve a random generation-growth method for reproducing three-dimensional random microstructures of porous media and a high-efficiency lattice Poisson-Boltzmann algorithm for solving the strongly nonlinear governing equations of electroos...

Abstract. We derive a mathematical model of a nematic electrolyte based on the Leslie-Ericksen theory of liquid crystal flow. Our goal is to investigate the nonlinear electrokinetic effects that occur because the nematic matrix is anisotropic, in particular, transport of ions in a direction perpendicular to the electric field as well as quadratic dependence of the induced flow velocity on the e...

It is demonstrated that the isoelectric concentration of ThCl(4) is much greater for electroosmosis in small-pored membranes (cellophane, collodion) than for electrophoresis of particles of the same material. An explanation for the difference is advanced, based on the influence of the small pores in preventing complete development of the electrical double layer.

Acoustic handling of nanoparticles in resonating acoustofluidic devices is often impeded by the presence acoustic streaming. For micrometer-sized chambers, this streaming typically driven viscous shear thin boundary layer near fluid-solid interface. Alternating current (ac) electroosmosis another boundary-driven phenomenon routinely used microfluidic for particle suspensions electrolytes. Here,...
