  2. Electrokinetic phenomena - Wikipedia

    en.wikipedia.org/wiki/Electrokinetic_phenomena

    Electrokinetic phenomena are a family of several different effects that occur in heterogeneous fluids, or in porous bodies filled with fluid, or in a fast flow over a flat surface. The term heterogeneous here means a fluid containing particles.

  3. Induced-charge electrokinetics - Wikipedia

    en.wikipedia.org/wiki/Induced-charge_Electrokinetics

    visualized induced-charge electrokinetic flow pattern around a carbon-steel sphere (diameter = 1.2 mm). Four induced vortices are shown using fluorescent particles with a diameter of 1.90 μm. The DC electric field is applied from left to right and equals 40V/cm. The dashed line represents the particle boundary.

  4. Electrohydrodynamics - Wikipedia

    en.wikipedia.org/wiki/Electrohydrodynamics

    Electrohydrodynamics (EHD), also known as electro-fluid-dynamics (EFD) or electrokinetics, is the study of the dynamics of electrically charged fluids. [1] [2] Electrohydrodynamics (EHD) is a joint domain of electrodynamics and fluid dynamics mainly focused on the fluid motion induced by electric fields.

  5. Electrokinetics - Wikipedia

    en.wikipedia.org/wiki/Electrokinetics

    Electrokinetic phenomena, a family of several different effects that occur in heterogeneous fluids; Zeta potential, a scientific term for electrokinetic potential; Electrokinetic remediation, a technique of using direct electrical current to remove particles from the soil; Electro-kinetic road ramp, a method of generating electricity

  6. Biefeld–Brown effect - Wikipedia

    en.wikipedia.org/wiki/Biefeld–Brown_effect

    The "Biefeld–Brown effect" was the name given to a phenomenon observed by Thomas Townsend Brown while he was experimenting with X-ray tubes during the 1920s while he was still in high school. When he applied a high voltage electrical charge to a Coolidge tube that he placed on a scale, Brown noticed a difference in the tube's mass depending ...

  7. Seismoelectrical method - Wikipedia

    en.wikipedia.org/wiki/Seismoelectrical_Method

    Electrokinetic effects are initiated by sound waves (typically P-waves) passing through a porous rock inducing relative motion of the rock matrix and fluid. Motion of the ionic fluid through the capillaries in the rock occurs with cations (or less commonly, anions) preferentially adhering to the capillary walls, so that applied pressure and ...

  8. History of electrophoresis - Wikipedia

    en.wikipedia.org/wiki/History_of_electrophoresis

    The electrokinetic phenomenon was observed for the first time in 1807 by Russian professors Peter Ivanovich Strakhov and Ferdinand Frederic Reuß at Moscow University, [4] who noticed that the application of a constant electric field caused clay particles dispersed in water to migrate.

  9. Streaming current - Wikipedia

    en.wikipedia.org/wiki/Streaming_current

    A streaming current and streaming potential are two interrelated electrokinetic phenomena studied in the areas of surface chemistry and electrochemistry. They are an electric current or potential which originates when an electrolyte is driven by a pressure gradient through a channel or porous plug with charged walls. [1] [2] [3]
