Effect of critical slowing down on local-density dynamics
Article Abstract:
The time scale for local solvent reorganizations, which may control solute dynamics, can become very long for low and near-critical-density supercritical fluids. The study has shown local solvent environments in compressible supercritical fluids to have interesting and varied structures, which change dramatically with state point.

Stochastic dynamics in near-critical supercritical fluids
Article Abstract:
An extension of the generalized Langevin equation (GLE) in order to model diffusion processes in near-critical fluids is presented. The diffusion coefficients differ substantially from the expected bulk value in a given initial nonequilibrium ensemble.
