Classical density functional treatment of polydisperse polarisable clusters
Clifford E. Woodward, David Ribar, Jan Forsman
Ion clustering has been proposed as a mechanism leading to the peculiar 'anomalous underscreening' phenomenon seen for electrostatic interactions between charge surfaces immersed i…
Polyampholyte model of ion clusters: double-layer interactions in the presence of dissociated simple salt
David Ribar, Clifford E Woodward, Jan Forsman
We explore interactions between equally charged surfaces, in the presence of simple salt and either neutral or monovalently charged polyampholytes. We consider the possibility of u…
Solvent-induced ion clusters generate long-ranged double-layer forces at high ionic strengths
David Ribar, Clifford E. Woodward, Jan Forsman
Recent experimental results by the Surface Force Apparatus (SFA) have identified a dramatic deviation from previously established theories of simple electrolytes. This deviation, r…
Exceptionally strong double-layer barriers generated by polyampholyte salt
David Ribar, Clifford E. Woodward, Jan Forsman
Experiments using the Surface Force Apparatus (SFA) have found anomalously long-ranged interactions between charged surfaces in concentrated salt solutions. Ion clustering have bee…
Cluster Formation induced by local dielectric saturation in Restricted Primitive Model Electrolytes
David Ribar, Clifford E. Woodward, Sture Nordholm +1
Experiments using the Surface Force Apparatus (SFA) have found anomalously long ranged charge-charge underscreening in concentrated salt solutions. Meanwhile, theory and simulation…
