Event details
We demonstrate how to dynamically tune the assembly of anisotropic colloidal particles adsorbed at fluid-fluid interfaces using dipolar capillary interactions. We exploit a previously discovered first-order phase transition and show how to spontaneously turn off these dipolar capillary interactions by exceeding a critical field strength, providing unprecedented control of the bottom-up fabrication of soft materials.
About Condensed Matter lunchtime seminars
This is a weekly series of informal talks given primarily by members of the institute of condensed matter and complex systems, 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..
