   Solvent hydrodynamics speed up crystal nucleation in suspensions of hard spheresRadu, Marc  ; Schilling, Tanja in Europhysics Letters (2014), 105 We present a computer simulation study on the crystal nucleation process in suspensions of hard spheres, fully taking into account the solvent hydrodynamics.

[more ▼] We present a computer simulation study on the crystal nucleation process in suspensions of hard spheres, fully taking into account the solvent hydrodynamics. If the dynamics of crystallization in this system were purely diffusive, the crystal nucleation rate would be inversely proportional to the solvent viscosity. However, we observe that the nucleation rate is enhanced at high viscosities with respect to the diffusive behaviour. This effect might explain the large discrepancy between the nuclation rates obtained by simulation and experiment that have been reported in the literature so far.

[more ▼] Purely entropic systems such as suspensions of hard rods, platelets and spheres show rich phase behavior. Rods and platelets have successfully been used as models to predict the equilibrium properties of liquid crystals for several decades. Over the past years hard particle models have also been studied in the context of non-equilibrium statistical mechanics, in particular regarding the glass transition, jamming, sedimentation and crystallization. Recently suspensions of hard anisotropic particles also moved into the focus of materials scientists who work on conducting soft matter composites. An insulating polymer resin that is mixed with conductive filler particles becomes conductive when the filler percolates. In this context the mathematical topic of connectivity percolation finds an application in modern nano-technology. In this article, we briefly review recent work on the phase behavior, confinement effects, percolation transition and phase transition kinetics in hard particle models. In the first part, we discuss the effects that particle anisotropy and depletion have on the percolation transition. In the second part, we present results on the kinetics of the liquid-to-crystal transition in suspensions of spheres and of ellipsoids.
