Researchers at Interdisciplinary Research Institute Target Chemical Physics (Dipolar correlations in structured solvents under nanoconfinement)

July 29, 2014

By a News Reporter-Staff News Editor at Physics Week -- A new study on Chemical Physics is now available. According to news originating from Villeneuve d'Ascq, France, by VerticalNews correspondents, research stated, "We study electrostatic correlations in structured solvents confined to nanoscale systems. We derive variational equations of Netz-Orland type for a model liquid composed of finite size dipoles."

Our news journalists obtained a quote from the research from Interdisciplinary Research Institute, "These equations are solved for both dilute solvents and solvents at physiological concentrations in a slit nanopore geometry. Correlation effects are of major importance for the dielectric reduction and anisotropy of the solvent resulting from dipole image interactions and also lead to a reduction of van der Waals attractions between low dielectric bodies. Finally, by comparison with other recently developed self-consistent theories and experiments, we scrutinize the effect of solvent-membrane interactions on the differential capacitance of the charged liquid in contact with low dielectric substrates."

According to the news editors, the research concluded: "The interfacial solvent depletion driven by solvent-image interactions plays the major role in the observed low values of the experimental capacitance data, while non-locality associated with the extended charge structure of solvent molecules only brings a minor contribution."
