Condensed Matter lunchtime seminar

Interaction and Flow of Colloidal Spheres at an Oil-Water Interface

  • Event time: 1:00pm until 2:00pm
  • Event date: 24th September 2018
  • Speaker: Iain Muntz (Formerly School of Physics & Astronomy, University of Edinburgh)
  • Location: Room 2511,

Event details

In my talk I will be looking at the interaction between interfacially adsorbed colloidal particles. While these particles behave as hard spheres in the bulk phase, when adsorbed to the interface a long range interaction appears. I will go through how we measure this interaction and an explanation for its origin.

I will then move on to look at the same system of interfacially adsorbed particles under flow. We do this using a novel setup which indirectly shears the interface. This is contrary to what has been seen before when probes are attached directly to the interface in order to induce shear. I will go through some analysis of preliminary results taken and comment on the connection between the first and second parts of my talk.

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..
