The microscopic structure and dynamic properties of an isotropic three-dimensional core-softened model fluid in disordered matrices of Lennard-Jones particles were studied. Molecular dynamics computer simulations in Grand Canonical ensemble were used as the methodological tools. It was shown that the microscopic structure of the fluid was characterized by anomalies similar to those found in a bulk model, but that it was affected by the fluid–matrix interactions. The dynamic properties also exhibited anomalous dependence on fluid density, but the magnitude of these anomalies was suppressed in comparison to the bulk fluid model. The anomalous behavior of the diffusion coefficient was attributed to structural changes in the first coordination shell of a given fluid particle. It seemed that the anomalies could only be suppressed at matrix densities which were higher than those studied in the present work.The Structural Properties and Diffusion of a Three-Dimensional Isotropic Core-Softened Model Fluid in Disordered Porous Media.
