Comparison of density functional and modified Poisson-Boltzmann structural properties for a spherical double layer
The density functional and modified Poisson-Boltzmann descriptions of a spherical (electric) double layer are compared and contrasted vis-a-vis existing Monte Carlo simulation data (for small ion diameter 4.25 · 10⁻¹⁰ m) from the literature for a range of physical parameters such as macroion surf...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The density functional and modified Poisson-Boltzmann descriptions of
a spherical (electric) double layer are compared and contrasted vis-a-vis
existing Monte Carlo simulation data (for small ion diameter 4.25 · 10⁻¹⁰ m)
from the literature for a range of physical parameters such as macroion surface
charge, macroion radius, valencies of the small ions, and electrolyte
concentration. Overall, the theoretical predictions are seen to be remarkably
consistent between themselves, being also in very good agreement
with the simulations. Some modified Poisson-Boltzmann results for the zeta
potential at small ion diameters of 3 and 2 · 10⁻¹⁰ m are also reported. |
