The surface tension of ionic liquids A mechanical formula

Abstract

We show how both the Kirkwood-Buff and the Triezenberg-Zwanzig expressions for the surface tension of neutral fluids can be applied to charged fluids if due care is taken of the singularities introduced by the Coulomb potential. An expression previously obtained within a density functional theory is recovered and an alternative, but equivalent, mechanical expression is proposed. © 1982 Taylor & Francis Group, LLC.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
