Professor Greg van Anders, University of MichiganAdvances in synthesis techniques have produced colloids and nanoparticles in a diverse array of shapes that can be assembled into bulk structures. That bulk structure is strongly affected by particle shape in idealized systems is widely established in the literature. However, this literature leaves open three key questions: (i) We know that shape affects structure, but how? (ii) Does shape continue to matter in experimental systems where other interactions are present? (iii) How do we tailor colloid shape for a target structure?

In this talk, we will discuss the generation of toroidal droplets and their stabilization against surface-tension-driven instabilities using yield stress materials. We will then discuss what happens when the drops are made out of nematic liquid crystal. In this case, when the anchoring is planar degenerate, we find that the director spontaneously twists and that the twisted structure remains irrespective of how thin or fat the tori are. Our interpretation is that this results from saddle-splay contributions to the Frank free energy of the system.
