“…Prinsen and Odijk calculated some of the parameters such as the collective diffusion coefficients of proteins, considering the interaction of electrostatic and adhesive forces. [8] Yu et al [9] and Zhong et al [10] also did similar work for the collective diffusion. Tarasenko discussed the collective diffusion in a one-dimensional homogeneous lattice.…”

Transport surrounding is full of all kinds of fields, like particle potential, external potential.Under these conditions, how elements work and how position and momentum redistribute in the diffusion? For enriching the Fick's law in ordinary, nonequilibrium statistics physics need to be used to disintegrate the complex process. This study attempts to discuss the particle transport in the onedimensional channel under external potential fields. Two type of potentials -potential well and barrier do not change the potential in total -are built during the diffusion process. There are quite distinct phenomena because of different one-dimensional periodic potentials. We meticulously explore reasons about why external potential field impacts transport by the subsection and statistics method. Besides, one of the evidences of Maxwell velocity distribution is confirmed in assumption of local equilibrium. In addition, we have also investigated the influence of temperature and concentration to the collective diffusion coefficient, by a variety of external force, attaching thermodynamics analyze to these opposite phenomena. So simply is this model that the most valuable point may be an idea, which relating flux to sectional statistics of position and momentum could be referenced in similar transport problems.

Based on the Nordholm's concept of Coulomb repulsive hole for plasma, a model of effective Coulomb potential is proposed to describe the charged fluids. Employing the classical density functional theory, the equilibrium structures of charged fluids confined in nano-cavities are calculated. Through the comparison with the numerical results, the effect of Coulomb correlation on the structure and excess adsorption is studied. In addition, the influence of Coulomb correlation on the structure is also calculated and studied under the condition of larger confinement. It is shown that the effective pair potential proposed here can be successfully used to predict the effects of Coulomb correlation on the structure and other physical chemical properties. Results obtained can provide some useful clues to the understanding of the correlation in other complex model potential system.
