Density functional theory for a macroion suspension
Patrick B. Warren
A density functional theory for a macroion suspension is examined, where the excess free energy corresponds to the macroion self energy arising from the polarisation of the support…
Simple models for charge and salt effects in protein crystallisation
Patrick B. Warren
A simple extension of existing models for protein crystallisation is described, in which salt ions and charge neutrality are explicitly incorporated. This provides a straightforwar…
Charged colloids at low ionic strength: macro- or microphase separation?
Patrick B. Warren
Phase separation in charged systems may involve the replacement of critical points by microphase separated states, or charge-density-wave states. A density functional theory for hi…
Moment free energies for polydisperse systems
Peter Sollich, Patrick B Warren, Michael E Cates
A polydisperse system contains particles with at least one attribute (such as particle size in colloids or chain length in polymers) which takes values in a continuous range. I…
Re-entrant Melting in Polydisperse Hard Spheres
Paul Bartlett, Patrick B. Warren
The effect of polydispersity on the freezing transition of hard spheres is examined within a moment description. At low polydispersities a single fluid-to-crystal transition is rec…
