In the first part we describe van der Waals interactions, derive generally-applicable density functional expressions for solute-mediated interactions with a focus on electrostatic interactions across aqueous electrolytes, and discuss interaction mechanisms involving the overlap of structured interfacial water layers. We then turn our attention to the long-debated hydration repulsion and review its quantitative investigation using classical molecular dynamics simulations.en0378-43712015105125Classical density functional theory | Electrostatic interactions | Hydration repulsion | MD simulations | Membrane interactions | Order parametersTechnology::620: EngineeringJournal Article10.1016/j.physa.2014.06.088Journal Article
