A theory of the dynamic electrophoretic mobility of a spherical soft particle (that is, a polyelectrolyte-coated spherical particle) in an oscillating electric field is presented. In the absence of the polyelectrolyte layer a spherical soft particle becomes a spherical hard particle, while in the ab

Accurate approximate formulas are obtained for the dynamic electrophoretic mobility of a cylindrical hard colloidal particle in an oscillating electric field for two cases where the cylinder is in a transverse field or in a tangential field. These formulas, expressed in terms of Hankel functions and

Dynamic mobility spectra of suspensions of semiconducting pyrolusite particles (manganese dioxide) have been measured by means of electroacoustics in different supporting electrolytes. The magnitude of the complex dynamic mobility spectra of these particles is small. At low frequency the magnitudes
\(\Lambda\) new electroacoustic instrument ( AcoustoSizer, Matec Applicd Sciences) has been used to measure the dynamic mobility of \(\mathrm{Na}\) kaolinite and \(\gamma\)-aluminium hydroxide (gibbsite) suspensions at \(\mathrm{MHz}\) frequencies. In both suspensions the particles consist of thin,
