Molecular simulations of charged complex fluids: A review

Molecular dynamics simulations of polyelectrolyte multilayering on a charged particle.

Molecular dynamics simulations of polyelectrolyte multilayering on a charged spherical particle revealed that the sequential adsorption of oppositely charged flexible polyelectrolytes proceeds with surface charge reversal and highlighted electrostatic interactions as the major driving force of layer deposition. Far from being completely immobilized, multilayers feature a constant surge of chain...

Predicting the Newtonian viscosity of complex fluids from high strain rate molecular simulations

The prediction of viscosity by molecular simulation has been a goal of molecular modeling essentially since its inception. With today’s computing power, the Newtonian or zero shear viscosity of a low molecular weight fluid can easily be determined using equilibrium and nonequilibrium molecular dynamics simulation methods. However, both methods are constrained to systems with relatively short re...

Transient molecular dynamics simulations of viscosity for simple fluids.

A transient molecular dynamics (TMD) method has been developed for simulation of fluid viscosity. In this method a sinusoidal velocity profile is instantaneously overlaid onto equilibrated molecular velocities, and the subsequent decay of that velocity profile is observed. The viscosity is obtained by matching in a least-squares sense the analytical solution of the corresponding momentum transp...
