Review of Scientific Instruments, 1948
A description is given of a transducer which utilizes, for the transformation of sonic to electrical energy, the electrokinetic potential developed by the movement of a fluid through a porous solid. The construction and calibration of the transducer are discussed, and results of measurements of the pressure fluctuations in oil pipe lines are presented.

Abstract The chapters concerns electrokinetic phenomena, treated in general and in the context of microfluidics. Bascic laws are reviewed. Electrokinetic equations are given, leading to Debye layer, elecroosmosis, sedimentation potential, electrophoresis, along with the various methods of separation used in the field, such as free ...

A novel electrokinetic micromixer
Sensors and Actuators A: Physical, 2004A novel microfluidic mixer based on the modulation of /spl zeta/-potential is proposed and demonstrated successfully. In contrast to previous micromixer work from other groups, this micromixer does not need complex three-dimensional serpentine microstructure or external pumps to generate chaotic advection pulsatile flow.

AbstractThe theoretical analysis and experimental demonstration of a new concept are presented for a non‐contact scanning probe, in which transport of fluid and molecules is controlled by electric fields. The electrokinetic scanning probe (ESP) enables local chemical and biochemical interactions with surfaces in liquid environments.

Up to now, we have only considered stationary or static charges, which are sources of electrostatic fields. Stationary charges are studied in electrostatics. Electrokinetics, on the other hand, is the branch of electromagnetism devoted to the study of electric currents (i.e.

Microemulsion Electrokinetic Chromatography
2008Microemulsion electrokinetic chromatography (MEEKC) is an attractive capillary electrophoretic technique in which a microemulsion is used as carrier electrolyte. Analytes may partition between the aqueous phase of the microemulsion and its oil droplets, which act as a pseudostationary phase. It is well suited for the separation of neutral analytes, but

Electrokinetics of metal cylinders
Physical Review E, 2019We study theoretically the rotation induced on an uncharged metal nanocylinder immersed in an electrolyte by AC electric fields. We consider the rotation of the cylinder when subjected to a rotating electric field (electrorotation) and the orientation of the cylinder in an AC field with constant direction (electro-orientation). The cylinder rotation is

Electrokinetics on superhydrophobic surfaces
Journal of Physics: Condensed Matter, 2012On a superhydrophobic surface a liquid is exposed to a large air-water interface. The reduced wall friction is expected to cause a higher electro-osmotic mobility. On the other hand, the low charge density of a superhydrophobic surface reduces the electro-osmotic mobility.
