Ion correlation driven like-charge attraction in multivalent salt solutions
Nikhil R. Agrawal, Ravtej Kaur, Carlo Carraro +1
The electrostatic double layer force is key to determining the stability and self-assembly of charged colloids and many other soft matter systems. Fully understanding the attractiv…
On the nature of overcharging and charge inversion in electrical double layers
Nikhil R. Agrawal, Chao Duan, Rui Wang
Understanding overcharging and charge inversion is one of the long-standing challenges in soft matter and biophysics. To study these phenomena, we employ the modified Gaussian reno…
Self-Consistent Description of Vapor-Liquid Interface in Ionic Fluids
Nikhil R. Agrawal, Rui Wang
Inhomogeneity of ion correlation widely exists in many physicochemical, soft matter, and biological systems. Here, we apply the modified Gaussian renormalized fluctuation theory to…
Electrostatic correlation induced ion condensation and charge inversion in multivalent electrolytes
Nikhil R. Agrawal, Rui Wang
The study of the electrical double layer lies at the heart of colloidal and interfacial science. The standard mean-field Poisson-Boltzmann (PB) theory is incapable of modeling many…
Inhomogeneous screening near a dielectric interface
Rui Wang, Zhen-Gang Wang
Screening is one of the most important concepts in the study of charged systems. Near a dielectric interface, the ion distribution in a salt solution can be highly nonuniform. Here…
On the theoretical description of weakly charged surfaces
Rui Wang, Zhen-Gang Wang
It is widely accepted that the Poisson-Boltzmann (PB) theory provides a valid description for charged surfaces in the so-called weak coupling limit. Here, we show that the image ch…
Theory of Polymer Chains in Poor Solvent: Single-Chain Structure, Solution Thermodynamics and Theta Point
Rui Wang, Zhen-Gang Wang
Using the language of the Flory chi parameter, we develop a theory that unifies the treatment of the single-chain structure and the solution thermodynamics of polymers in poor solv…
Continuous Self Energy of Ions at the Dielectric Interface
Rui Wang, Zhen-Gang Wang
We present a simple, unified theory for the self-energy of an ion near a dielectric interface. Our theory accounts for both the short-range (solvation) and long-range (image force)…
