Rheological evidence of adsorbate-mediated short-range steric forces in concentrated dispersions
TL;DR: In this article, the effect of a series of anionic adsorbates on the rheology of a model zirconia concentrated suspension has been studied in detail, and the results are all consistent with the adorbates producing a steric barrier equivalent to the size of the adsorbed molecule along the attractive van der Waals interaction.
Journal ArticleDOI
Rheological and zeta potential behaviour of kaolin and bentonite composite slurries
Pek-Ing Au,Yee-Kwong Leong +1 more
TL;DR: In this article, the results of the yield stress-pH and zeta potential -pH behavior of pure and mixed bentonite-kaolin clays were evaluated and a high and low Ca(II) content mixture was used to control and tailoring rheological properties of kaolin suspension with bentonite for specific applications.
Journal ArticleDOI
A fully coupled multiscale shale deformation-gas transport model for the evaluation of shale gas extraction
TL;DR: In this article, a set of partial differential equations are derived to define various flow and deformation processes: (1) mechanical equilibrium equation that defines the shale deformation; (2) gas flow in the kerogen system of matrix; (3) gas flows in the inorganic system of matrices; and (4) hydraulic fracture system.
Journal ArticleDOI
Interparticle forces arising from adsorbed polyelectrolytes in colloidal suspensions
TL;DR: In this article, the effects of molecular weight and concentration of polyacrylic acid (PAA) on the yield stress τy of ZrO2 suspensions were evaluated, and the Mw range studied was from 1656 to 750000.
Journal ArticleDOI
Effect of Particle Size on Colloidal Zirconia Rheology at the Isoelectric Point
TL;DR: In this paper, the effects of particle concentration and size on the yield stress of ZrO{sub 2} suspensions at a well-defined surface chemistry condition of the isoelectric point (IEP) were examined.
