Phase Separation of Binary Clusters
Mixtures of two chemical species may sometimes separate into two
distinct phases. An oil-water mixture is a familiar example. The movie
shows the analog of this phase separation or de-mixing process in
microscopic clusters composed of about 100 molecules. The different
segments of the movie consider cases where dumbbell-shaped or spherical
clusters are formed depending on the nature of the molecules. The
science behind the simulation is the study of the new properties matter
exhibits on small length scales.
