Event details

Self-assembly of colloidal particles has enormous potential as a bottom-up means of structure fabrication because of the scope for tuning the interparticle interactions[1,2]. However, examples of colloidal self-assembly into target structures via a priori designed building blocks are still rather limited[3] The key to the success of programmed self-assembly as a means of structure fabrication is the ability to encode the target structure into the building blocks. In this presentation I will talk about computational approaches to programmed assembly into supracolloidal architectures[4,5,6,7] maintaining a close tie with contemporary experimental research. I will present illustrative examples, employing anisotropic colloidal particles such as magnetic and patchy particles, for targeted chiral superstructures, and highlight a hierarchical self-assembly scheme for reconfigurable hollow spherical structures.

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..
