Abstract:  Colloidal particles accumulate and organize at fluid interfaces via capillary interactions. We study pair interactions and structure formation around spherical particles with pinned contact lines. Particles attract to apparent contact and organize in near trapped structures that reflect the underlying curvature field. We have derived pair potentials to describe these interactions. The particles distort […]

Abstract:  Several chemical processes involve the use of mutually immiscible molecules, for example a water-soluble catalyst is used in combination with oil-soluble reagents to produce water soluble products. There are two possible strategies to run these processes. A mutual solvent can be used to promote mixing of the otherwise immiscible molecules; however, such a system […]
