Electrokinetic Properties of Acid-Activated Montmorillonite Dispersions [PDF]

Separation Science and Technology, 2010
In this study, the influence of pH, electrolyte concentration, and type of ionic species on the electrokinetic properties (zeta potential and electrokinetic charge density) of the acid-activated montmorillonite mineral have been investigated using the ...

Electrokinetic transport properties of deoxynucleotide monophosphates (dNMPs) through thermoplastic nanochannels [PDF]

Analytica Chimica Acta, 2018
The electrokinetic behavior of molecules in nanochannels (< 100 nm in length) have generated interest due to the unique transport properties observed that are not seen in microscale channels.

Characterization of Electrokinetic Properties of Nanofluids

Journal of Nanoscience and Nanotechnology, 2008
The effects of pH value, surfactant, and electrolyte concentration on zeta potential, particle agglomeration, and thermal conductivity of nanofluids are investigated. The zeta potential of TiO2 (15 nm) nanoparticles in deionized water of different pH values was measured and the iso-electric point was found to be between 4.9 and 5.2.

Electrokinetics:  The Properties of the Stagnant Layer Unraveled

Langmuir, 1998
When an aqueous solution moves tangentially to a charged surface, as in electrophoresis and all other electrokinetic phenomena, a thin water layer remains immobilized:  the stagnant layer. The plane separating the stagnant layer and the mobile part of the fluid is the slip plane.

Electrokinetic properties of scheelite

Journal of Colloid and Interface Science, 1974
The electrophoretic mobility of scheelite (CaWO4) from King Island, Australia, has been measured in a variety of inorganic electrolytes, mostly at constant ionic strength and controlled pH. Scheelite develops a negative surface charge in its saturated solution, but the zeta-potential may be reduced to zero by increasing the calcium concentration to ...

A Study of the Electrokinetic and Stability Properties of Nitrofurantoin Suspensions. I: Electrokinetics

Journal of Pharmaceutical Sciences, 1990
An experimental investigation is described of the electrokinetic properties of nitrofurantoin. The experiments are based on measurements of electrophoretic mobility in suspensions of this drug and the calculation of its zeta potential (zeta) following two different procedures. A simple mechanism is proposed for explaining the sign of the surface charge
