Specific ion effects

We are seeking students to perform fundamental research into how different ions exert influence in a myriad of systems.

Colloidal systems in highly concentrated salt solutions

We are studying colloidal systems in highly concentrated salt solutions. Here a number of surprising and unexplained things happen that are associated with surprisingly long-ranged electrostatic forces

Migration of carbon dioxide injected in aquifers: convection, diffusion and dissolution

Underground carbon sequestration looks essential if the world is going to keep global warming well below 2oC.  This project will explore the physics underlying migration of injected carbon dioxide, to better understand when it will dissolve and sink to the deep earth before there is any chance of it migrating upwards.

Surface forces and the behaviour of colloidal systems

We measure the basic forces that operate between molecules that are manifest at interfaces. These forces control the stability of colloidal systems from blood to toothpaste. We use very sensitive techniques that are able to measure tiny forces with sub nanometer distance resolution. Understanding these forces enables us to predict how a huge variety of colloidal systems will behave.

Nanobubbles are simply nanosized bubbles. What makes them interesting? Theory tells us they should dissolve in less than a second but they are in some cases stable for days.
