Abstract:A phenomenological scheme and a corresponding kinetic model are developed to demonstrate the interactions between cation and extrinsic vacancy fluxes in ionic solutions. The solution examined consists of two monovalent species and one divalent species (with matching extrinsic vacancies) on the cation sublattice. It is demonstrated that the monovalent cations always tend to flow up the vzlcancy (or divalent cation) gradient and, in the event that a monovalent species is initially uniformly distributed, to subse… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
