In a report we published earlier, Apple is testing its Hi-Res music streaming potential
, reportedly pushing for audio equipment makers to manufacture platform-specific audio products that will connect to Apple's devices via the Lightning port.
Of electrokinetic phenomena, streaming potential
and seismoelectric effects play an important role in geophysical applications.
Widely used as an indicator of the stability of particle suspensions and colloidal samples, surface zeta potential is traditionally measured using the specialist technique of streaming potential
. The company's Surface Zeta Potential Cell eliminates the need for a dedicated solution, allowing users to measure the zeta potential of surfaces in an aqueous medium on a standard instrument.
As a result the measured self potential is a sum of streaming potential
occurring on the boundary mineral--fluid, diffusion potential and connected gradient of ion concentration and mineralization potential (arising from ion content), thermoelectric potential (resulting from thermal gradient) and bioelectric potential (presence of plant roots).
The situation can be reversed and the solution can be forced to flow through a plug of packed particles (Adamson and Gast, 1997; Masliyah and Bhattacharjee, 2006); the zeta potential of the particles is calculated from the streaming potential
measured by this technique.
If, on the other hand, one is interested in the electrical potential near to the surfaces of fibers, it is recommended to use a method called "fiber-pad streaming potential
The streaming potential
method was used, as it has been shown to be the most appropriate electrokinetic technique to study electrokinetic properties i.e.
To quote Fukada, whom the others regard as a pioneer in the subject, "Stress-induced electricity in bone is caused by both piezoelectricity in collagen and streaming potential
in microcanals in bone." Or, in other participants' words: piezoelectricity for dry bone, streaming potential
for wet bone.
The four most commonly studied electrokinetic phenomena--electroosmosis, streaming potential
, electrophoresis, and sedimentation potential--are listed in Chapter 7.
