Title: Bubbles and Droplets as Granular Analogues of Continuum Materials
Abstract: In recent years we have developed a method to produce microscopic monodisperse oil droplets in an aqueous environment. With an attractive interaction between the droplets, these monodisperse droplets form perfect crystalline aggregates, while a blend of small and large droplets allows us to prepare a disordered glass. By carefully tuning the adhesion forces between the droplets, the aggregates provide model systems for studying various physical phenomena that are not accessible by investigating molecular systems. Here I will provide a brief overview of experiments we have carried out to address two fundamental questions. How does a system transition from crystal to glass, when blending large and small droplets? And secondly, how does a system transition from granular, when there are a few particles, to many particles, where continuum models are valid. These experiments enable us to study the transition from few-to-many, and crystal-to-glass.</pre>
