Crystallization kinetics in colloidal hard spheres via real space analysis using Confocal microscopy — •Sahana Kale and Hans Joachim Schöpe — Institut für Angewandte Physik, Universität Tübingen, Germany

The nucleation rate densities from experimental and theoretical data diverge by several orders of magnitudes and the curves are qualitatively different. One of our research goals is to find the underlying reason for this discrepancy, if there is any.

Crystallization of meta-stable colloidal hard sphere suspensions is studied in real space using laser scanning confocal microscopy. Direct imaging in three dimension offers the unique possibility to observe crystal nucleation and growth on particle level giving detailed information about the fluid to crystal phase transformation
