Anomalous zeta potential in foam films [PDF]

open access: yes, 2014
Electrokinetic effects offer a method of choice to control flows in micro and nanofluidic systems. While a rather clear picture of these phenomena exists now for the liquid-solid interfaces, the case of liquid-air interfaces remains largely unexplored ...

Zeta potential measurement in bioactive collagen

open access: yesMaterials Research, 2004
The focus of this work is to show the influence of surface charge on the bioactivity of modified collagen fiber surface. Because silica plays an important role on bone mineralization process, silica obtained by a sol-gel process was used as a surface ...

Prediction of Zeta Potential for Tropical Peat in the presence of different Cations using Artificial Neural Networks

open access: yesInternational Journal of Electrochemical Science, 2011
Zeta potential (ζ) of the peat was measured by electrophoresis in the presence of different cations. Artificial neural networks (ANNs) were developed for the prediction of the ζ of peat in the presence of the cations at different pH values and ionic ...

Investigations on the adsorption, wettability and zeta potential of anionic surfactant in limestone

open access: yesAnais da Academia Brasileira de Ciências, 2021
The understanding of the mechanisms that affect oil production in carbonaceous reservoirs has become increasingly necessary, particularly in limestone, which mostly features oil wettability properties that diminishes petroleum recovery.

Measurement of streaming potential coupling coefficient in sandstones saturated with natural and artificial brines at high selenity [PDF]

open access: yes, 2010
We report experimental measurements of the streaming potential coupling coefficient in sandstones saturated with NaCl-dominated artificial and natural brines up to 5.5 M (321.4 g L−1 of NaCl; electrical conductivity of 23 S m−1).

STREAMING CURRENT INDUCED BY FLUID FLOW IN POROUS MEDIA [PDF]

open access: yesEarth Science Malaysia, 2018
Streaming current is induced by the relative motion between a fluid and a solid surface under a fluid pressure difference. In this work, a theoretical model for the streaming current coefficient in porous media is firstly developed based on the fractal

Enhanced Dyeing of Polypropylene Using Fluorine–Oxygen Gas Mixtures

open access: yesColorants, 2023
Surface fluorination with pure F2 gas can easily make the surface on PP (polypropylene) hydrophobic, and it causes limited dyeability, as reported in a previous paper.

Casimir effect in rugby-ball type flux compactifications [PDF]

open access: yes, 2007
As a continuation of the work in \cite{mns}, we discuss the Casimir effect for a massless bulk scalar field in a 4D toy model of a 6D warped flux compactification model,to stabilize the volume modulus.

Wettability Studies Using Zeta Potential Measurements

open access: yesJournal of Chemistry, 2015
Wettability studies have been carried out on reservoir rocks using different techniques such as the Amott-Harvey method, the USBM method, and the contact angle method, all with limitations.
