The Laplace transformed diffusion equation is solved for finite diffusion in planar, cylindrical and spherical geometry with a Nemstian or an impermeable diffusion layer boundary condition. Analytical expressions are presented generalized as the Laplace transformed concentration to flux ratio at the

In the present paper some boundary value problems are examined, concerning diffusion toward a planar, a spherical, or a dropping electrode, held at constant potential. In so doing, it will be shown with practical examples that the direct application both of the unified numerical procedure and of the
A simple matrix formalism presented by Callaghan [J. Magn. Reson. 129, 74 -84 (1997)], and based on the multiple propagator approach of Caprihan et al. [J. Magn. Reson. A 118, 94 -102 (1996)], allows for the calculation of the echo attenuation, E(q), in spin echo diffusion experiments, for practical
