Assuming that ion transport is governed by diffusion and migration and electroneutrality holds true, the in silico ECT 1D model can be approximated by a new split model describing ion transport in a two-step procedure.
This model can account for mass transport by convection, diffusion and migration and for the presence of homogeneous reactions.
The configuration of the electrolytic cell was such that mass transfer was governed only by transient diffusion and migration, in the absence of convection.
This first paper examines the space charge appearing through ionic absorption at the metal-liquid contact and conditioned by the phenomena of diffusion and migration in the bulk liquid.
Distortion from Warburg-like response observed for both polymer films was explained by either differences in relaxation times of diffusion and migration processes, or by impedance of ionic channels with "anomalous" frequency dispersion.
Charging of polymer films was in terms of both models controlled by charge transport processes being ion diffusion and migration in the first case, and polymer film and ionic conductivities in the second case.
As the electron transfer step (1) is intrinsically fast, and as the film remains porous throughout its growth, the rate of film growth is limited by physical parameters such as ionic diffusion and migration in the solution.
Its expansion westward and southward, through diffusion and migration, was stimulated by a shift from bronze- to ironworking.
Swelling will open up the pores and facilitate migration by diffusion, and hence it is possible that some nanoparticles were released from the hydrogels during the swelling study, although their hydrophobicity makes this scenario less likely.
