Effective shape and phase behaviour of short charged rods
Eelco Eggen, Marjolein Dijkstra, René van Roij
We explicitly calculate the orientation-dependent second virial coefficient of short charged rods in an electrolytic solvent, assuming the rod-rod interactions to be a pairwise sum…
The polydisperse cell model: Non-linear screening and charge renormalization in colloidal mixtures
Aldemar Torres, Gabriel Tellez, Rene van Roij
We propose a model for the calculation of renormalized charges and osmotic properties of mixtures of highly charged colloidal particles. The model is a generalization of the cell m…
Nonlinear screening and gas-liquid separation in suspensions of charged colloids
Bas Zoetekouw, Rene van Roij
We calculate phase diagrams of charged colloidal spheres (valency and radius ) in a 1:1 electrolyte from multi-centered nonlinear Poisson-Boltzmann theory. Our theory takes…
Finite-Thickness and Charge Relaxation in Double-Layer Interactions
Aldemar Torres, Rene van Roij, Gabriel Tellez
We extend the classical Gouy-Chapman model of two planar parallel interacting double-layers, which is used as a first approximation to describe the force between colloidal particle…
Theory of the isotropic-nematic transition in dispersions of compressible rods
K. Shundyak, R. van Roij, P. van der Schoot
We theoretically study the nematic ordering transition of rods that are able to elastically adjust their mutually excluded volumes. The model rods, which consist of a hard core sur…
Hard colloidal rods near a soft wall: wetting, drying, and symmetry breaking
K. Shundyak, R. van Roij
Within an Onsager-like density functional theory we explore the thermodynamic and structural properties of an isotropic and nematic fluid of hard needle-like colloids in contact wi…
