Interparticle Interactions in Nonlocal Media: Attraction and Repulsion from Charge-Polarization Coupling
Ali Behjatian, Madhavi Krishnan
Recent measurements of microsphere interactions in diverse media suggest that the standard dielectric-continuum models of solution-phase interactions are fundamentally incomplete.…
Direct measurement of the attractive electrosolvation force between a pair of colloidal particles
Sida Wang, Angela Le, Rowan Walker-Gibbons +1
In solution, electrically like-charged particles can experience a strong and long-ranged attraction that leads to the formation of stable, slowly reorganizing clusters. The attract…
Measurements of molecular size and shape on a chip
Xin Zhu, Timothy JD Bennett, Konstantin C Zouboulis +6
Size and shape are critical discriminators between molecular species and states. We describe a micro-chip based high-throughput imaging approach offering rapid and precise determin…
Chemical control of self-assembly by the electrosolvation force
Sida Wang, Rowan Walker-Gibbons, Bethany Watkins +2
Self-assembly of matter in solution generally relies on attractive interactions that overcome entropy and drive the formation of higher-order molecular and particulate structures.…
Surface polarization strongly influences electrostatics in a nonlocal medium
Ali Behjatian, Ralf Blossey, Madhavi Krishnan
Electrostatics in the solution phase is governed by free electrical charges such as ions, as well as by bound charges that arise when a polarizable medium responds to an applied fi…
