Streaming potential—a general affinity sensor
Biosensors, 1986Electrokinetic phenomena, such as streaming potential or streaming current, have so far been used for studies of unspecific adsorption of ionic compounds on various materials. This paper shows that streaming potential measurements can also be used for studies of biospecific interactions. Several different interactions were studied, e.g.

Streaming potentials in chemically modified bone
Journal of Orthopaedic Research, 1988AbstractDirect streaming experiments with no significant mechanical deformation have been performed to determine the constituent or constituents of bovine tibia mainly responsible for the production of streaming potentials. Following the approach of Frank and Grodzinsky (5), selective removal of either main constituent—collagen or hydroxyapatite—of the

The Stream Function and the Velocity Potential Function
The Mathematical Gazette, 1954The stream function, ψ, is a function specially suited for dealing with two-dimensional flow while the velocity potential, ϕ, is a function which may be used with either two- or three-dimensional flow. In two-dimensional flow, the chief utility of ψ and ϕ occurs when they satisfy Laplace's equation ∇

Rapid stream stimulation and the recognition potential
Electroencephalography and Clinical Neurophysiology, 1992The "recognition potential" is an electrical response of the brain that occurs for recognizable, but not for non-recognizable, images. When a recognizable image evokes it, the more rostral of a pair of vertically oriented occipital electrodes reaches an initial positive peak at about 200-250 msec.

Streaming Potential Across Nafion Membranes
Berichte der Bunsengesellschaft für physikalische Chemie, 1989AbstractMembranes / Nonequilibrium Phenomena / Streaming Potential / Thermodynamics / Transport PropertiesThe streaming potential Δϕ which arises between the uni‐univalent electrolyte solutions of the same concentration separated by nafion 125 membrane in the presence of a pressure difference ΔPapplied across the membrane has been studied.

Langmuir, 2005
Methodology for determining the zeta potential of a disk-shaped sample by both streaming potential and streaming current measurements is presented. Integration of Laplace's equation within one radius of the disk surface revealed that the streaming potential decreased strongly in the surface normal direction.

Variance of streaming potential measurements
Journal of Membrane Science, 1999We evaluated sources of variance in the measurement of the surface streaming potential of flat sheet specimens of cellulose di/triacetate membranes with a commercial electrokinetic analyzer. Two measurement methods were evaluated: the instrument's standard operating procedure, which continuously ramps the flow past the specimen, and a modified ...

Streaming Potential and the SP Log
Transactions of the AIME, 1958Published in Petroleum Transactions, AIME, Volume 213, 1958, pages 170–179. Abstract Published laboratory data have established that very significant streaming potentials can exist across mud cakes subjected to pressure differentials such as exist between a mud column and formation fluids. Since shale
