IAS Fellows' Seminar - The Physics of Capillary Assembly

10th February 2020, 13:00 to 14:00, Seminar Room, Institute of Advanced Study, Dr Suzie Protiere (Institut Jean le Rond d’Alembert, Sorbonne University)

Abstract

In this talk, Dr Suzie Protiere will describe various simple model systems where the spontaneous self-assembly of objects is provoked by the interplay between capillary forces and other forces such as gravity or elasticity at liquid interfaces. For example, at a small scale, capillary forces can be coupled with gravity to force the self-assembly of particles floating on a liquid into a large granular raft. A droplet placed on elastic fibres has a surface tension strong enough to induce their collapse. Many sectors of industry require to understand and control the assembly of small objects. For example in food processing, cosmetics or detergence emulsions or foams are stabilized with particles and understanding their interactions is key. In the fabrication processes of paper or textiles, fibres interact with liquids, which has consequences on the strengthening, swelling or fibrillation of such fibrous media. Finally, she will discuss the strong aesthetic appeal of self-assembly as it generates spontaneously new patterns, shapes and materials.
