Correlated Diffusion of Colloidal Particles near a Liquid-Liquid Interface
Optical microscopy and multi-particle tracking are used to investigate the cross-correlated diffusion of quasi two-dimensional colloidal particles near an oil-water interface. The behaviors of the correlated diffusion along longitudinal and transverse direction are asymmetric. It is shown that the characteristic length for longitudinal and transverse correlated diffusion are particle diameter d...
متن کاملDiffusion at the liquid-vapor interface.
Recently, the intrinsic sampling method has been developed in order to obtain, from molecular simulations, the intrinsic structure of the liquid-vapor interface that is presupposed in the classical capillary wave theory. Our purpose here is to study dynamical processes at the liquid-vapor interface, since this method allows tracking down and analyzing the movement of surface molecules, thus pro...
متن کاملInterface morphologies in liquid/liquid dewetting
The dynamics and morphology of a liquid polystyrene (PS) film on the scale of a hundred nanometer dewetting from a liquid polymethylmethacrylate (PMMA) film is investigated experimentally and theoretically. The polymers considered here are both below their entanglement lengths and have negligible elastic properties. A theoretical model based on viscous Newtonian flow for both polymers is set up...
متن کاملIonic Disruption of the Liquid-Liquid Interface
The interface formed between an aqueous salt solution and a hydrophobic liquid has been investigated using molecular dynamics simulations. The salt solutions of NaCl, NaNO3, and Na2SO4 have been studied to determine their presence and distribution in the interfacial region and their effect on interfacial water molecules. Density and orientation profiles reveal the formation of ionic double laye...
متن کاملNonequilibrium molecular dynamics simulation of diffusion at the liquid-liquid interface.
Molecular Dynamics simulations are performed to study the dynamical properties of molecules in the presence of a liquid-liquid (L/L) interface. In the vicinity of the interface the movement of the particles, coupled with the thermal fluctuations of the interface, can make the evaluation of properties such as the self-diffusion coefficient, particularly difficult. We explore the use of the Evans...
