extensions to study electrochemical interfaces - a contribution to the theory of ions

in the present study an alternative model allows the extension of the debye-hückel theory (dht) considering time dependence explicitly. from the electro-quasistatic approach (eqs) done in earlier studies time dependent potentials are suitable to describe several phenomena especially conducting media as well as the behaviour of charged particles in arbitrary solutions acting as electrolytes.this leads to a new formulation of the meaning of the nonlinear poisson-boltzmann equation (pbe). if a concentration and/or flux gradient of particles is considered the original structure of the mpbe will be modified leading to a new nonlinear partial differential equation (npde) of the third order. it is shown how one can derive classes of solutions for the potential function analytically by application of an algebraic method. the benefit of the mathematical tools used here is the fact that closed-form solutions can be calculated without any numerical approximations.
