Using a thermodynamic model and Monte Carlo simulations I will show that a pure fluid of spherical particles interacting via an SALR (short-range attraction and long-range repulsion) pair-potential has micelle-like behaviour. A non-classical crystal nucleation pathway is proposed to operate via these precursor liquid-like clusters. These findings could have implications for our understanding of mesostructure and crystal nucleation in a wide range of liquid mixtures, potentially including many biologically relevant ones, normally thought to be completely miscible and uniform at the mesoscale.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
