The ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate, bmimPF 6 , is a neoteric solvent of current interest. The maxima are shown to he due to the very high viscosity of the solvent, 3.26 poise, which yields an unusually high Schmidt number (Sc) of 3.5 × 10 7 , compared to a value of about 10 3 for aqueous solutions. It is estimated that over 100 revolutions of the disk are needed to achieve the Levich limiting current following application of a voltage step to the disk. The current transient resulting from application of a voltage step to the rotating disk is found to be in agreement with previously developed theory, even for these highly viscous systems. Analysis of the transient permits a determination of Sc values without measurement of the viscosity and density of the solvent, or diffusion coefficient of the reacting species.}, number={11}, journal={JOURNAL OF THE ELECTROCHEMICAL SOCIETY}, author={Boxall, DL and JJ O'Dea and Osteryoung, RA}, year={2002}, month={Nov}, pages={E468–E471} }

Limiting currents measured in deionized latex suspensions yield a corresponding effective charge, Z*. Electrostatic binding of an inner layer of counterions to the particle renders Z* < Z. Voltammetrically determined charges agree with the intrinsic and effective Stokes charges as determined by titration and electrophoresis, respectively. ζ- Potentials calculated from the measured electrophoretic mobility of the particles yield the Loeb charge number, which agrees more closely with Z than with Z*. For existing data on spherically charged macroions, Z*/Z decreases with increasing ratio of intrinsic charge to macroion radius, Z/a. This finding is supported by effective charge values calculated from the cell model using the nonlinear Poisson-Boltzmann equation with the convention that Z* is the charge found between the c(r)/ 〈c〉 = 1 boundary and the cell wall.}, number={17}, journal={ANALYTICAL CHEMISTRY}, author={Roberts, JM and JJ O'Dea and Osteryoung, JG}, year={1998}, month={Sep}, pages={3667–3673} }
