Exploring EDL using Liquid State Theory

A Hierarchical Classical Density-Functional Theory for Ions and Coarse-Grained Dipolar Water

A thermodynamically consistent classical density-functional theory (cDFT) bridging a species-resolved civilized electrolyte model with a PC-SAFT coarse-grained molecular description of water. Developed at the Mathematical Institute, Charles University, this research models the simultaneous redistribution of ions, orientation of molecular solvent dipoles, and liquid packing restructuring at charged interfaces.
