We propose a generalized Debye-Hückel (DH) theory by using a recent Poisson-Fermi model that accounts for the steric, correlation, and polarization effects of ions and water treated as nonuniform spheres with interstitial voids. The generalized DH theory reduces to the classical one when these effects are not considered. " - Debye correlation function
