Abstract Scope |
The conditions for formation of single-component metallic glasses and their stability are fascinating and long-standing problems in glass science. It is therefore of interest that it is possible to form stable glasses with monodisperse (i.e., single-size) colloidal particles. These are particles in suspension, which form phases similar to those formed by atoms. Since the particles are “fat” (~1µm) and “slow” (~10Hz), they can be individually tracked by confocal microscopy. This makes it possible to follow crystallization, melting and glass formation on the particle level.
This talk will review the experimental conditions for formation of these colloidal glasses, as well as their stability against crystallization. The colloidal technique also makes it possible to observe both homogeneous nucleation as well as growth of crystals from the liquid on the particle level. The results will be compared to existing kinetic models and their implications for glass formation will be analyzed. |
