Query: Dipolar Capillary Interactions between Tilted Ellipsoidal Particles
  Adsorbed at Fluid-Fluid Interfaces   Capillary interactions have emerged as a tool for the directed assembly of
particles adsorbed at fluid-fluid interfaces, and play a role in controlling
the mechanical properties of emulsions and foams. In this paper, following
Davies et al. [Advanced Materials, 26, 6715 (2014)] investigation into the
assembly of ellipsoidal particles at interfaces interacting via dipolar
capillary interactions, we numerically investigate the interaction between
tilted ellipsoidal particles adsorbed at a fluid-fluid interface as their
aspect ratio, tilt angle, bond angle, and separation vary. High-resolution
Surface Evolver simulations of ellipsoidal particle pairs in contact reveal an
energy barrier between a metastable tip-tip configuration and a stable
side-side configuration. The side-side configuration is the global energy
minimum for all parameters we investigated. Lattice Boltzmann simulations of
clusters of up to 12 ellipsoidal particles show novel highly symmetric
flower-like and ring-like arrangements.
