Local theory for ions in binary liquid mixtures

M Bier, A Gambassi, S Dietrich - The Journal of Chemical Physics, 2012 - pubs.aip.org
The influence of ions on the bulk phase behavior of binary liquid mixtures acting as their
solvents and on the corresponding interfacial structures close to a planar wall is investigated …

Recent advances in liquid mixtures in electric fields

Y Katsir, Y Tsori - Journal of Physics: Condensed Matter, 2016 - iopscience.iop.org
When immiscible liquids are subject to electric fields interfacial forces arise due to a
difference in the permittivity or the conductance of the liquids, and these forces lead to shape …

Topological-defect-induced surface charge heterogeneities in nematic electrolytes

M Ravnik, JC Everts - Physical review letters, 2020 - APS
We show that topological defects in an ion-doped nematic liquid crystal can be used to
manipulate the surface charge distribution on chemically homogeneous, charge-regulating …

How ions in solution can change the sign of the critical Casimir potential

F Pousaneh, A Ciach, A Maciołek - Soft Matter, 2014 - pubs.rsc.org
We show that hydrophilic ions present in a confined, near-critical aqueous mixture can lead
to an attraction between like charge surfaces with opposing preferential adsorption of the …

The effect of antagonistic salt on a confined near-critical mixture

F Pousaneh, A Ciach - Soft Matter, 2014 - pubs.rsc.org
We consider a near-critical binary mixture with addition of antagonistic salt (hydrophilic
