It is demonstrated that self-diffusion in dense liquids can be considered a random walk process; its characteristic length and time scales are identified. This represents an alternative to the often ...assumed hopping mechanism of diffusion in the liquid state. The approach is illustrated using the one-component plasma model.
The application fields of colloid and interface chemistry are very wide, covering many aspects such as industrial and agricultural production, daily chemistry, enhanced oil recovery, and so on. The ...traditional experimental analysis of a colloid and interface chemistry system includes various instrumental analysis methods such as spectroscopy, rheometer, microscopes, etc. In recent decades, molecular simulation has become an important research method in this field. It can investigate at the molecular level and provide mechanisms or insights that are hard or even impossible to obtain from an experiment. Many applications of molecular simulation have been reported in the literature, such as the behavior of surfactant, self-assembly, enhanced oil recovery, adsorption around interface, etc. This reprint has collected ten research articles which relate to the application of molecular dyamics simulation in colloide and interface chemistry.

Viscosity and self-diffusivity data for ten liquid metals are correlated by use of the theory of corresponding states and the reducing factors defined by Helfand and Rice. The transport data are used ...to determine relative values of the pair-potential energy parameters, which are found to have a linear relationship with melting point. By using density data, it is possible to construct reduced correlations for diffusivity and viscosity as functions of reduced temperature without explicitly choosing distance parameters
