Spread-charge model for electric double layers.

Electric double layers in concentrated electrolytes exhibit a range of complex phenomena, including steric crowding, overscreening, and voltage-dependent capacitance. Mean-field theories offer a mathematically and conceptually simple framework for describing these phenomena and relating them to experimentally relevant...

Origin of the Anomalous Guest Polymer Selectivity in Complex Coacervates

Complex coacervates─liquid condensates resulting from liquid–liquid phase separation of oppositely charged polymers─have attracted broad interest in artificial cells, drug delivery vehicles, and smart nanoreactors. The functionality of these applications is significantly influenced by the coacervate’s ability to enca...

How Topology Shapes the Phase Behavior of Polyelectrolytes

We develop a topology-specific theory of polyelectrolyte coacervation using the random phase approximation and apply it to both simple and complex coacervation. Our results for stars and dendrimers show that more compact chain topologies display a greater propensity for liquid-liquid phase separation, as a function of...
