Packing Patterns of Spherical Particles


In collaboration with the Bon Group, we studied the packing pattern of silica nanoparticles on the surface of spherical polystirene latex droplets with Monte Carlo simulations [1].

The experimental system has been modelled as a set of interacting spheres on a spherical surface. The information supplied by this model has been complementary to the experimental data, to determine whether thermodynamic equilibrium has been reached and to study the effect of the polydispersity of the spherical nanoparticles on the self-assembled structure.
