| Abstract Scope |
Recent advances in the ability to experimentally control the size, shape, and composition of nanoparticles have significantly broadened the possibilities to create novel mesoscale structures as a result of their “bottom-up” assembly. Here, we present a novel mesoscale simulation approach that utilizes diffuse interface fields to capture and investigate the dynamic assembly processes for arbitrarily shaped particles with arbitrary charge density and/or dipole moment. Illustrative results demonstrating the method’s ability to predict a wide variety of colloidal crystal structures, with a particular focus on binary lattices consisting of positively- and negatively-charged particles, will be presented. Furthermore, this mesoscale approach has also been extended to include the capillary forces experienced by particles segregated at fluid-fluid interfaces. We will present simulations of the complex evolutions of multi-phase fluid mixtures in which particle absorption to the interfaces significantly alters the dynamics of system. |
