TLDR
Binary mixtures of suspended hard-sphere colloidal particles, radius ratio R B /R A =0.58, were observed to undergo entropically driven freezing transitions into both the AB 2 and AB 13 superlattice structures at different relative proportions of the two species.Abstract:
Binary mixtures of suspended hard-sphere colloidal particles, radius ratio ${\mathit{R}}_{\mathit{B}}$/${\mathit{R}}_{\mathit{A}}$=0.58, were observed to undergo entropically driven freezing transitions into both the ${\mathit{AB}}_{2}$ and the ${\mathit{AB}}_{13}$ superlattice structures at different relative proportions of the two species. The structures were identified by powder light crystallography and by electron microscopy of the dried solid phases. An approximate (constant volume) phase diagram containing three eutectics was determined. The results are compared with earlier work at size ratio 0.62.read more

Long-Lived Non-Equilibrium Interstitial-Solid-Solutions in Binary Mixtures
TL;DR: In this paper, Filion et al. performed particle resolved experimental studies on the heterogeneous crystallisation process of two compo- nent mixtures of hard spheres and compared these with molecular dynamics simulations of homogenous nucleation.

TL;DR: In this paper, the results of an experimental study on the spectral behavior of the Raman Q branch of nitrogen in the mixed solid are presented, where the experiments have been performed at ambient temperature as a function of pressure up to 15 GPa.
