Electrochemical Determination of Diffusion Anisotropy in Molecularly-Structured Materials

Evans, Louise A.; Thomasson, Matthew J.; Kelly, Stephen M.; Wadhawan, Jay

Abstract

Theory is presented for the case of two-dimensional diffusion anisotropy in axiosymmetric systems, which, advantageously and indirectly, affords a unified theory of diffusive mass transport at planar, microdisk (or nanodisk) and cylindrical electrodes in isotropic media. A strategy is proposed to determine the extent of diffusion anisotropy in experimental data; proof-of-concept is considered, via a lamellar lyotropic liquid crystalline system.
