Colloids in confinement: From two-dimensional melting to membrane transport

If you have a question about this talk, please contact Stephen Walley .

Colloidal suspensions have long been regarded as an excellent source of experimental model systems, due to their large size, slow timescales and inherent tunability. In this talk, I will discuss two examples of how complex natural phenomena can be studied by building systems in which colloids are confined to one- and two-dimensional geometries. In particular, in 2D, we have established the full phase behaviour of the simplest two-dimensional system, hard disks, by studying the structure and dynamics of colloidal monolayers. In 1D, we can gain an insight into transport through porous membranes by studying colloidal dynamics in microscale channels with tuneable potential landscapes.
