We develop the theory of transient electrophoresis of a weakly charged. infinitely long cylindrical colloidal particle under an application of a transverse or tangential step electric field. Transient electrophoretic mobility approaches steady electrophoretic mobility with time. We derive closed-form expressions for the transient electrophoretic mobility of a cylinder without involvin... https://www.markymarkscott.com/product-category/1-00-1nn/
