Effect of Model Polycyclic Aromatic Compounds on the Coalescence of Water-in-Oil Emulsion Droplets

A series of molecular dynamics simulations were performed to investigate the effect of polycyclic aromatic compounds (PACs) on the coalescence of two water droplets in oil (i.e., n-heptane and toluene). Our simulations revealed that, in both solvents, the presence of PACs can significantly hinder the coalescence or even completely prevent it. Detailed structural and kinetic analysis provided insights into the underlying mechanisms for the...
