Continuity of the nucleation of bulk and surface phases.
Nucleation of a new bulk phase is almost always heterogeneous: It occurs at a surface. Nucleation of a new surface phase also occurs at a surface of course. We study nucleation in an Ising model with both bulk and surface (prewetting) transitions. We find no clear distinction between nucleation of the bulk and surface phases. As the bulk transition is crossed, the phase that is nucleating chang...
متن کاملOn the influence of a patterned substrate on crystallization in suspensions of hard spheres.
We present a computer simulation study on crystal nucleation and growth in supersaturated suspensions of mono-disperse hard spheres induced by a triangular lattice substrate. The main result is that compressed substrates are wet by the crystalline phase (the crystalline phase directly appears without any induction time), while for stretched substrates we observe heterogeneous nucleation. The sh...
متن کاملFlory-Huggins theory for athermal mixtures of hard spheres and larger flexible polymers.
A simple analytic theory for mixtures of hard spheres and larger polymers with excluded volume interactions is developed. The mixture is shown to exhibit extensive immiscibility. For large polymers with strong excluded volume interactions, the density of monomers at the critical point for demixing decreases as one over the square root of the length of the polymer, while the density of spheres t...
متن کاملEffect of polymer chain-length polydispersity on the phase behavior of model athermal mixtures of colloids and flexible self-excluding polymers
The effect of polymer polydispersity on the fluid–fluid demixing of an athermal mixture of colloids and self-excluding polymers is analysed with the first-order thermodynamic perturbation theory (TPT1) of Wertheim. The colloidal particles and the segments making up the polymer chains are modeled as hard spheres of different diameters. The polydispersity of the polymer is represented by a distri...
متن کاملCrystal nucleation of hard spheres using molecular dynamics, umbrella sampling, and forward flux sampling: a comparison of simulation techniques.
Over the last number of years several simulation methods have been introduced to study rare events such as nucleation. In this paper we examine the crystal nucleation rate of hard spheres using three such numerical techniques: molecular dynamics, forward flux sampling, and a Bennett-Chandler-type theory where the nucleation barrier is determined using umbrella sampling simulations. The resultin...
