Fluids of clusters in attractive colloids.
We show that colloidal particles with attractive interactions induced by a nonadsorbing polymer exhibit a stable phase consisting of a fluid of clusters of particles. This phase persists even in the absence of any long-range repulsion due to charge, contrary to expectations based on simulation and theory. Cluster morphology depends strongly on the range of the interparticle attraction: With a s...
متن کاملTunneling conductivity in composites of attractive colloids.
In conductor-insulator nanocomposites in which conducting fillers are dispersed in an insulating matrix, the electrical connectedness is established by inter-particle tunneling or hopping processes. These systems are intrinsically non-percolative and a coherent description of the functional dependence of the conductivity σ on the filler properties, and in particular of the conductor-insulator t...
متن کاملLattice Boltzmann for Colloids in Binary Fluids
The implementation of solid colloidal particles suspended in a binary fluid mixture via the lattice Boltzmann method is described. To represent colloids in a binary mixture, boundary conditions for mass and momentum at the solid-fluid interface are extended to include a conserved compositional order parameter. The parallelisation of the fluid-particle problem is addressed, and its scaling inves...
متن کاملClusters in simple fluids
This article concerns the correspondence between thermodynamics and the morphology of simple fluids in terms of clusters. Definitions of clusters providing a geometric interpretation of the liquid-gas phase transition are reviewed with an eye to establishing their physical relevance. The author emphasizes their main features and basic hypotheses, and shows how these definitions lead to a recent...
متن کاملAging in short-ranged attractive colloids: a numerical study.
We study the aging dynamics in a model for dense simple liquids, in which particles interact through a hard-core repulsion complemented by a short-ranged attractive potential, of the kind found in colloidal suspensions. In this system, at large packing fractions, kinetically arrested disordered states can be created both on cooling (attractive glass) and on heating (repulsive glass). The possib...
