Influence of roughness and capillary size on the zeta potential values obtained by streaming potential measurements

Surface and Interface Analysis, 2020
Streaming potential measurements are performed to determine the zeta potential of flat surfaces, particles, or fibers. Although the zeta potential is a well‐defined property of solid surfaces in a liquid, there are indications that the absolute values of

Zeta potential of phosphors

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1995
Abstract The zeta potentials of several oxide, sulfide, and oxysulfide phosphors were measured in isopropyl alcohol (IPA) and IPA containing dissolved nitrate salts and water. The zeta potentials of phosphors in IPA without dissolved salts are negative.

Zeta potential measurement of calcium carbonate

Journal of Colloid and Interface Science, 2003
The problem of scaling, which one finds in industrial heat exchangers, particularly in atmospheric coolers in nuclear power stations, depends on calcium carbonate deposits from fresh water. To better understand this phenomenon, we have examined the eventual implication of superficial electric charge of precipitated crystal nuclei.

Zeta Potential Determination of Targeted Nanoparticles

2021
Abstract In a dispersion system, colloids interact with one another. It is assumed that these interactions are promoted by two main forces, London-van der Waals forces that lead to attraction and electromagnetic effects that leads to repulsion. The zeta potential (ZP) is the electrical potential at the surface of a hydrodynamic shear plane.

The zeta potential of mineral fibres

Journal of Hazardous Materials, 2014
For the first time, the zeta (ξ) potential of pathogenic mineral fibres (chrysotiles, amphiboles and erionite) was systematically investigated to shed light on the relationship between surface reactivity and fibre pathogenicity. A general model explaining the zeta potential of chrysotile, amphiboles and erionite has been postulated. In double distilled

Zeta Potential Measurements on Passive Metals

Journal of Colloid and Interface Science, 1995
In this study, one shows that the zeta potential can be determined on stainless steel sheet surfaces by streaming potential measurements, These surfaces are in fact covered with a thin oxyhydroxide film known as ''the passive film.'' Zeta potential depends on the solution composition and the surface final conditions, The zeta potentials on AISI 304 ...

Effect of Substrate and Bacterial Zeta Potential on Adhesion of Mycobacterium smegmatis.

Langmuir, 2019
Bacterial adhesion is described as a multistep process of interactions between microbes and the substrate, beginning with reversible contact, followed by irreversible adhesion.

Polysaccharide zeta-potentials and protein-affinity

Physical Chemistry Chemical Physics, 2017
Theζ-potential, a parameter typically obtained by model-dependent transformation of the measured electrophoretic mobility, is frequently used to understand polysaccharide–protein complexation.

The zeta-potential of cement

Cement and Concrete Research, 1985
Abstract Zeta-potential measurements provide new informations on cement hydration, gel structure formation and the effects of chemical admixtures. The formation and significance of a zeta-potential of cement in aqueous suspension is discussed with respect to the hydration of cement and some new data on the zeta-potential of cement and fly ash under ...
