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.
In general, the phenomena relate to the direct conversion of electrical energy into kinetic energy, and vice versa. In the first instance, shaped electrostatic fields (ESF's) create hydrostatic pressure (HSP, or motion) in dielectric media. When such media are fluids, a flow is produced. If the dielectric is a vacuum or a solid, no flow is ...
They are briefly described in the article on electrophoresis and in details in many books on colloid and interface science. [ 3 ] [ 4 ] [ 5 ] [ 11 ] There is an IUPAC Technical Report [ 12 ] prepared by a group of world experts on the electrokinetic phenomena.
Thomas Townsend Brown (March 18, 1905 – October 27, 1985) [1] was an American inventor whose research into odd electrical effects led him to believe he had discovered a type of anti-gravity caused by strong electric fields.
Electrokinetics or electrokinetic may refer to: Electrohydrodynamics, the study of the dynamics of electrically charged fluids; Electrokinetic phenomena, a family of several different effects that occur in heterogeneous fluids; Zeta potential, a scientific term for electrokinetic potential
Sedimentation potential. Electrokinetic phenomena are a family of several different effects that occur in heterogeneous fluids or in porous bodies filled with fluid. The sum of these phenomena deals with the effect on a particle from some outside resulting in a net electrokinetic effect.
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]
There are detailed descriptions of the interfacial DL in many books on colloid and interface science [18] [19] [20] and microscale fluid transport. [21] [22] There is also a recent IUPAC technical report [23] on the subject of interfacial double layer and related electrokinetic phenomena. detailed illustration of interfacial DL
