Frictional and viscous effects during transport in nanopores

暴露在含有分子大小的孔(纳米孔)的材料中的气体混合物被吸附，形成不存在于主体中的物质状态。作用在混合物组分上的差别力促进了工业和环境方面的重要分离。然而，对受限流体的传输却知之甚少。最近，我们利用计算机模拟取得了进展，并提出了一个非常成功的理论。这些研究揭示了来自封闭固体表面原子的散射的关键作用。已经开始了对单一球形物种的理论研究，现在正在设想将其扩展到其他物种和混合物。

Gas mixtures exposed to materials containing molecular sized pores (nanopores) are adsorbed, forming states of matter not existing in the bulk. Differential forces acting on the components of mixtures promote industrially and environmentally important separations. However, transport of confined fluids has been poorly understood. Recently we have made progress using computer simulation, and have proposed a highly successful theory. These investigations have revealed the crucial role of scattering from the surface atoms of the confining solid. Theoretical investigation of single spherical species has been initiated, and extension to other species and to mixtures is now envisaged.
