Event details

Droplets in an emulsion require some form of stabiliser to prevent coalescence. Traditionally this stabiliser has been a molecular surfactant. However, it is also possible to stabilise emulsions using mesoscopic solid particles, and this can lead to interesting behaviours not possible with conventional surfactants. For example, it is possible for a single particle to be shared by two droplets, creating particle "bridges", which can cause the emulsion to aggregate. I will talk about our efforts to understand the causes of this phenomena, and the ways in which we can control it.

About Condensed Matter lunchtime seminars

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..
