The diffusive dynamics and electrochemical regulation of weak polyelectrolytes across liquid interfaces
Giulia Laura Celora, Ralf Blossey, Andreas Munch +1
We propose a framework to study the spatio-temporal evolution of liquid-liquid phase separation of weak polyelectrolytes in ionic solutions. Unlike strong polyelectrolytes, which c…
Counterion-controlled phase equilibria in a charge-regulated polymer solution
Giulia L. Celora, Ralf Blossey, Andreas Münch +1
We study phase equilibria in a minimal model of charge-regulated polymer solutions. Our model consists of a single polymer species whose charge state arises from protonation-deprot…
The electric double layer at the interface between a polyelectrolyte gel and salt bath
Matthew G. Hennessy, Giulia L. Celora, Andreas Münch +2
The electric double layer (EDL) that forms at the interface between a polyelectrolyte gel and a salt bath is studied using asymptotic and numerical methods. Specifically, matched a…
A kinetic model of a polyelectrolyte gel undergoing phase separation
Giulia L. Celora, Matthew G. Hennessy, Andreas Münch +2
In this study we use non-equilibrium thermodynamics to systematically derive a phase-field model of a polyelectrolyte gel coupled to a hydrodynamic model for a salt solution surrou…
The dynamics of a collapsing polyelectrolyte gel
Giulia L. Celora, Matthew G. Hennessy, Andreas Münch +2
We analyse the dynamics of different routes to collapse of a constrained polyelectrolyte gel in contact with an ionic bath. The evolution of the gel is described by a model that in…
Degenerate Mobilities in Phase Field Models are Insufficient to Capture Surface Diffusion
Alpha A Lee, Andreas Münch, Endre Süli
Phase field models frequently provide insight to phase transitions, and are robust numerical tools to solve free boundary problems corresponding to the motion of interfaces. A body…
Slip-controlled thin film dynamics
R. Fetzer, M. Rauscher, A. Münch +2
In this study, we present a novel method to assess the slip length and the viscosity of thin films of highly viscous Newtonian liquids. We quantitatively analyse dewetting fronts o…
