Transverse ion diffusion inside fixed charge narrow pores
The diffusion dynamics of ions inside a planar slit with a high constant surface charge density was studied by solving the Smoluchowski/HypernnetedChain equation for the mean first passage times. The behavior of local properties, such as the potential of mean force, is correlated with the time i...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The diffusion dynamics of ions inside a planar slit with a high constant surface
charge density was studied by solving the Smoluchowski/HypernnetedChain
equation for the mean first passage times. The behavior of local
properties, such as the potential of mean force, is correlated with the time
it takes for an ion to get adsorbed at the surface, and also with macroscopic
properties like the salt rejection coefficient and the apparent diffusion constant
in porous media, as a function of pore size. We show that the width of
the walls has an important effect on the transverse ion diffusion process. |
