Self-assembly and phase separation in patchy particles
Inspired by work using patchy particles to model colloidal systems and protein solutions, we quantify the phase separation and self-assembly of patchy particles using both simulations and theory. In particular, master curves are identified, and a corresponding framework is developed that can be used to parameterize patchy particle models using experimental data.
Aqueous solutions of oppositely charged polymers, under certain conditions, can macrophase separate yielding a polymer rich phase known as a complex coacervate and a polymer poor phase often with vanishing polymer concentrations. We explore this phase separation in systems of block copolymers containing charged blocks and neutral, hydrophilic blocks using a combination of simulation and theory.
Polymer properties: databases and predictions
In collaboration with Prof. Juan de Pablo and colleagues at University of Chicago, we are generating a database of polymer properties. The resulting database will be accompanied by an integrated webtool that computes properties of polymeric systems using popular polymer theories.
Hydrodynamic properties of dilute particle solutions
We are improving the efficiency of a code, ZENO, to compute several quantities including the intrinsic viscosity and hydrodynamic radius. Additionally, the code is used to explore the role of shape on hydrodynamic properties for a class of cube-like particles. Computations are directly compared with experimental results and are found to be accurate within experimental uncertainty.
