This National Science Foundation (NSF) Engineering (CFDA 47.041) program grant of $362,000.00 awarded to The Johns Hopkins University on August 1, 2024 aims to develop models to predict and describe the behavior of colloidal assemblies on curved surfaces. The project will use microscopy, computer experiments, and feedback control to understand the dynamics of particle-scale microstructure formation and evolution on curved surfaces. The goals are to gain fundamental insights into how different shaped particles assemble into ordered microstructures on curved topographies, and to enable feedback control to rapidly achieve target low-defect microstructures. This research is expected to enable the fabrication of novel synthetic materials that mimic natural structures and have important multifunctional properties for emerging technologies like optical coatings, solar cells, and flexible electronics. No sub-awards are planned under this grant.
