V09_Electroosmosis Mechanism in Microfluidics

Electroosmosis can occur in both microchannels and macrochannels.

The application of an axial magnetic field is needed for electroosmosis to occur in microfluidic systems.

Ion transport occurs only in the bulk fluid, not in the Electrical Double Layer (EDL).

The Electric field in electroosmosis acts as a net force on strongly bounded electric charges in the EDL.

The Helmholtz-Theory is related to the mechanism of Electroosmosis.

In electroosmosis, moving ions drag their surrounding fluid molecules due to the gravitational effect.

In electroosmosis, the Debye length must be larger than the channel diameter.

In electroosmosis, the electric field is assumed to be homogeneous in the direction perpendicular to the Electrical Double Layer (EDL).

Electroosmosis only occurs in two-phase turbulent flow systems.

As per the assumptions, the mechanical properties of the system are not constant in electroosmosis.

Outside the Electrical Double Layer (EDL), fluid in electroosmosis is charged by ions and experiences irrotational Coulomb forces.

In the matched asymptotic approach for electroosmosis, fluid motion outside the EDL is primarily driven by ions.

Electroosmosis (EO) is a mechanism that involves the flow of solvent molecules in a micro channel due to an applied electric field.

The Electric Double Layer (EDL) is associated with the accumulation of ions at the solid-liquid interface.

The Debye length represents the distance over which the surface charge decays to about 37% of its value at the surface.

Helmholtz theory is primarily concerned with the flow profile in microchannels.

Gouy-Chapman theory is related to the calculation of the ζ-Potential at the solid-liquid interface.

AC-Electroosmotic Mixer involves the use of DC-Electroosmotic Pumps with a travelling wave.
