gave attention and conducted preliminary studies on inducing particle-wall effect in electroosmotic flow; Peng then experimentally found that the higher the zeta potential of the electrical double layer around the surface of the polarizable solid, the more particles agglomerated; demonstrating the feasibility of using micronanoparticle manipulation to induce electroosmosis. Harbin Institute of Technology, Peng and Jia innovated the use of ITO conductive glass as the electrode, based on the principle of induced electroosmotic flow and implementation of micronanoparticle manipulation.
This causes movement of water and dissolved organic and inorganic materials in subsurface soils from one electrode (anode) to the other (cathode) under electroosmosis as a result of current movement from anode to cathode.
PIR was in an anionic form in the BGE of pH 9.0 and eluted after electroosmosis.
During electrodialysis water transport occurs across the membranes due to electroosmosis and osmosis [19].

In recent years, time periodic electroosmosis has been studied intensively due to the recent development of microfluidic devices.
He provided a theoretical and experimental framework, drawing from electrohydrodynamics, electroosmosis, and normal-mode stability analysis, to explain the physics behind commonly seen electrokinetic flow instabilities.
First, the electroosmosis in the ionomer moves the cation and water to the cathode side by the electrostatic force when an electric field is applied.
The emphasis is on simulating direct-current electrokinetic phenomena such as electroosmosis, electrophoresis, dielectrophoresis, and induced-charge electrokinetics; these phenomena have been widely used to manipulate fluids and particles in microfluidic and nanofluidic devices for various applications.
Irrespective of the type of microelectrodes used, the AC electrokinetic effects involved in the transport and trapping of particles are DEP, electrothermal flow (ETF), and electroosmosis. Briefly, DEP results when a polarizable particle is subjected to a spatially non-uniform electric field.
