(704c) Evaporation-Induced Assembly of Colloidal Crystals
AIChE Annual Meeting
Thursday, November 2, 2017 - 1:04pm to 1:21pm
We performed massive-scale, explicit-solvent molecular dynamics simulations to study the evaporation-induced nucleation and growth of a colloidal crystal. We classified the structure of crystallizing colloids using a machine-learning approach, and showed how the crystal nucleates and grows from the drying air-solvent interface. Complementary implicit solvent simulations were performed to demonstrate the nontrivial role that solvent plays in controlling the crystallization process. Our work has important implications for the processing of colloidal crystals from solution and nonequilibrium molecular modeling.
