Chronoamperometric sizing and locating of spherical particles via potential-step transients

Abstract:

The precise size of a spherical glass particle, its distance from the center of a microdisk electrode, and its exact location within an array of three noncollinear microdisk electrodes are determined by using simple Cottrellian-like potential-step chronoamperometric experiments. To first elucidate the size of a glass sphere and its distance from the center of the electrode, the sphere was positioned at arbitrary distances between the center of the sphere and the center of the electrode and a ...
