The kinetics of the micelle-to-micelle transition in a lipid (lecithin) + surfactant (bile salt) system was studied using neutron scattering. Lecithin and bile salt form micelles at high concentrations, which grow in length with dilution to form elongated, or worm-like micelles. The relatively fast (far below 1s) micelle-micelle transition can be studied using a stopped flow cell which achieves short mixing times. A general introduction to the system will be presented as well as initial results from recent experiments.
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..
