CORR model calculations. (A) Excess chemical potential Inline graphic for TPFB for three values of Inline graphic. (B) Ion distributions at the water (Inline graphic)/DCE (Inline graphic) interface illustrate back-to-back electrical double layers at Inline graphic in units of molarity. (C) TPFB number density profile Inline graphic times the volume Inline graphic, where Inline graphic nm is the ion diameter, for three values of Inline graphic. (D) Comparison of the PB (Gouy–Chapman), PB/MD (PB plus ion–solvent interactions), and CORR (PB/MD plus ion–ion correlations) models for the TPFB ion concentration (in molarity units) near the interface at Inline graphic.
