Abstract Scope |
Bicontinuous structures form frequently in nature as a result of phase separation. These structures continue to evolve due to the excess surface energy toward structures with larger feature sizes. Currently, there is no theory that predicts the morphology resulting from such evolution. In this presentation, the findings from phase field simulations of coarsening in a variety of systems, ranging from those with bulk diffusion to surface diffusion, as well as different volume fractions and mobilities, are summarized. The morphologies of the structures are characterized via interfacial shape distributions and phase/curvature auto-correlations, and their topologies are also quantified. A comparison to nanoporous gold structure is presented, and implications of particle detachment and reattachment are discussed. |
