Crystallography on Spherical Surfaces

POSTER

Abstract

We encapsulate micron sized colloidal particles inside w/o emulsion droplets. We control particle-particle and particle-interface interactions, so that the particle stay close to the interface but without penetrating the w/o interface. Monolayered colloidal crystallite form near the spherical interface at equilibrium. We use this system to study how the topological defects and disclinations diff use and relax on spherical surfaces.
