The free energy of a weakly curved, isolated macroion embedded in a symmetric 1:1 electrolyte solution is calculated on the basis of linear Debye-Hückel theory, thereby accounting for nonelectrostatic Yukawa pair interactions between the mobile ions and of the mobile ions with the macroion surface, present in addition to the electrostatic Coulomb potential. The Yukawa interactions between anion-anion, cation-cation, and anion-cation pairs are independent from each other and serve as a model for… 


Excluded volume effects in macromolecular forces and ion-interface interactions.
The pronounced dependence of the interplate pressure and ionic partition coefficients on the magnitude and the range of core interactions indicates excluded volume effects as an important ion specificity and a non-negligible ingredient for the stability of macromolecules in electrolyte solutions.
A simple model to investigate the effects of non-Coulombic interactions on the structure of charged interfaces
A simple field theoretical model is considered for an electrified interface in which the electrolyte solution is in contact with a charged hard wall. The model for the electrolyte includes Coulombic
Incorporation of ion and solvent structure into mean-field modeling of the electric double layer.
How various theoretical models predict structural properties of the electric double layer such as the differential capacitance and compare some of these predictions with computer simulations are discussed.
The Poisson-Helmholtz-Boltzmann model
This work presents a mean-field model of a one-component electrolyte solution where the mobile ions interact not only via Coulomb interactions but also through a repulsive non-electrostatic Yukawa potential, and demonstrates that the model is consistent with the contact theorem.

It is found that the predictions from the modified PHB model are the same as those from the classical Poisson-Boltzmann theory, indicating that nonelectrostatic ion-ion interactions and steric effects are negligible.
Ion size effects upon ionic exclusion from dielectric interfaces and slit nanopores
A previously developed field-theoretic model (Coalson et al 1995 J.?Chem.?Phys. 102 4584) that treats core collisions and Coulomb interactions on the same footing is investigated in order to
Poisson-Helmholtz-Boltzmann model of the electric double layer: analysis of monovalent ionic mixtures.
The present work applies the Poisson-Helmholtz-Boltzmann model to ionic mixtures, consisting of monovalent cations and anions that exhibit different Yukawa interaction strengths, and suggests an intricate interplay between electrostatic and nonelectrostatic interactions.
Role of ion hydration for the differential capacitance of an electric double layer.
The interplay between excluded volume and hydration-mediated interactions on the differential capacitance is analyzed and it is demonstrated that for small surface charge density the mean-field model based on the Carnahan-Starling equation is able to capture the Monte Carlo simulation results.
Differential capacitance of an electric double layer with asymmetric solvent-mediated interactions: mean-field theory and Monte Carlo simulations.
Because the added solvent-mediated interaction potential is comparatively soft, the mean-field model is able to qualitatively - and in some cases quantitatively - reproduce all Monte Carlo simulation results, even at high surface charge densities of the electrode.
Slits, plates, and Poisson-Boltzmann theory in a local formulation of nonlocal electrostatics.
The local formalism is reviewed and shown how it can be applied to a structured liquid in slit and plate geometries, and the Poisson-Boltzmann theory for a charged plate in a structured solvent with counterions is solved.
