Crystallization in one and two component charged colloidal systems — •Patrick Wette, Hans Joachim Schöpe, and Thomas Palberg — Institut für Physik der Universität Mainz

We investigated the nucleation kinetics of aqueous suspensions of Polystyrene spheres in the deionized state using static light scattering and Avrami theory. Phase behaviour and growth kinetics were determined in parallel from microscopy. For a mixture of 68nm and 100nm sized particles the phase diagram shows a pronounced minimum at 20% 68nm particles which is reflected in both crystallization kinetics and elasticity.
