Deciphering microscopic mechanisms driving assembly and flow of soft materials
Soft materials such as colloidal dispersions, polymers, emulsions, and biological macromolecules are ubiquitous in the natural world. Recent experimental advances have led to the fabrication of soft-matter-based nanostructures that can switch shape, assembly, and flow behavior in response to changes in their chemical or mechanical environment, opening pathways for novel medical, energy, catalysis, and automotive applications. This talk describes our work employing molecular dynamics simulations to understand the microscopic mechanisms that drive structure and property control in soft materials. We will explore: a shape-design mechanism in flexible polymeric nanoparticles based on tuning their surface charge patterns, a cooperative encapsulation process that drives ligand- and peptide-functionalized cargo in protein nanocages, and a salt dialysis approach to self-assemble multilayered and ordered core-shell arrays starting from a one-pot mixture of virus-like nanoparticles. Finally, we will discuss the shear thinning of alkane-based machine lubricants at high strain rates and pressures, demonstrating its origins lie in thermally activated molecular rearrangements rather than evolution in molecular order.
