Numerical Solution of the Electrokinetic Equations for Multi-ionic Electrolytes Including Different Ionic Size Related Effects

Micromachines, 2018
One of the main assumptions of the standard electrokinetic model is that ions behave as point-like entities. In a previous work (López-García, et al., 2015) we removed this assumption and analyzed the influence of finite ionic size on the ...

Performance repair of building materials using alumina and silica composite nanomaterials with electrodynamic properties

Open Chemistry
In recent years, the service life of building materials has become the focus of attention. Among them, the service life of concrete and steel bars is particularly affected by the corrosion of external ions (such as Cl−) in the environment.

Accuracy evaluation of zeta-potential measurement using current monitoring technique and closed electrokinetic cell technique

Journal of Fluid Science and Technology, 2018
The present study was performed to evaluate and to improve the measurement accuracies for zeta-potentials of particle and wall. Electric potentials near colloid particle surfaces and channel wall surfaces are defined as the zeta-potential of particle and

Electrokinetic properties of calcium aluminate hydrates [PDF]

Colloid and Polymer Science, 1978
The surface charge of Ca3Al2(OH)12 in water and NaOH solutions is negative when the solution is saturated towards this compound. When Ca3A12(OH)12 is formed during the reaction of Ca3A12O6 with water and NaOH solutions a positive surface charge is present. This positive charge is also found for other hydrates existing during this reaction; it indicates

Comparison of adsorption affinity of ionic polyacrylamide for the surfaces of selected metal oxides

Adsorption Science & Technology, 2017
The influence of metal oxide type on the adsorption affinity of anionic polyacrylamide for the solid surface was studied. There were selected three metal oxides: chromium(III) oxide, zirconium(IV) oxide and aluminium(III) oxide.
