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.

暴露于含有分子大小的孔（纳米孔）的材料的气体混合物被吸附，形成本体中不存在的物质状态。 作用在混合物组分上的不同力促进了工业和环境重要的分离。 然而，封闭流体的运输一直知之甚少。 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。 这些研究揭示了封闭固体表面原子散射的关键作用。 单一球形物种的理论研究已经开始，现在设想扩展到其他物种和混合物。
