Improved Desalination by Polymer Grafting
Mamta Yadav, Clifford E. Woodward, Jan Forsman
Freshwater scarcity demands desalination technologies that are efficient, scalable, and sustainable. Capacitive deionisation (CDI) is promising but remains limited by inefficient i…
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…
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…
On the Existence of Prewetting in Supracritical Fluid Mixtures
Jan Forsman, Clifford E. Woodward
In this communication we demonstrate the existence of a first-order prewetting transition of a supracritical model polymer solution adjacent to an attractive surface. The model flu…
