  • © 2016 by John Wiley & Sons, Inc. All rights reserved. The crystallization of a metastable melt is one of the most important nonequilibrium phenomena in condensed matter physics. Colloidal hard spheres offer the simplest and direct realization of crystallization. To address the effects of small polydispersity changes on crystallization of hard-sphere suspensions, it has been necessary to develop methods to prepare and characterize suspensions with subtle differences in size distribution. It has been demonstrated, that polydispersity can be tuned by fractionation, a technique that has been applied to both submicron- and micron-sized particles. Scanning or transmission electron microscopy, as well as light scattering, can be used to determine the size distribution of a colloidal suspension. Smart colloids, such as poly-N-isopropylacrylamide (PNIPAM) microgels, are responsive to external stimuli, such as temperature and pressure, and pH and salt concentration, if copolymerized with other concentration than the fluid-fluid separation region of neutral microgels.
