Divalent Cation-Mediated Polyanion Attraction in Aqueous Solution

APS March Meeting · 2023

Explains why calcium and other multivalent ions cause charged polymers to precipitate out of solution, and proposes design rules for polymers that resist this failure mode. Applies enhanced-sampling molecular dynamics to compute the effective interaction between polymer chains across varying salt concentration, temperature, and monomer chemistry.

Structure of Polyelectrolyte and Multi-Valent Ion Complexes

APS March Meeting · 2023

Characterizes how calcium ions bind to charged polymers: the energetics, the preferred binding sites along the chain, and a method to extract binding isotherms from enhanced-sampling molecular dynamics.
