Electroacoustic studies of moderately concentrated colloidal suspensions
Abstract
From electroacoustic theory it is now possible to determine the dynamic electrophoretic mobility of colloidal particles from measurements in any suspension for which the particle size is small compared to the sound wavelength (R. W. O'Brien, J. Fluid Mech., 1990, 212, 81); for dilute suspensions of spherical particles there is a simple formula for calculating the zeta potential from such mobility measurements (R. W. O'Brien, J. Fluid Mech., 1988, 190, 71). In this paper we present experimental verification of the theory for a latex and a cobalt phosphate sol, both of which are monodisperse, over a range of electrolyte concentrations and pH. We also present electroacoustic titration data on two polydisperse TiO2 sols, and discuss the discrepancies that result when these data are compared with the monodisperse theory.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
