Frictional and viscous effects during transport in nanopores. 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. ....Frictional and viscous effects during transport in nanopores. 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.Read moreRead less
Multicomponent Transport in Nanopores. Good understanding of transport mechanisms in nanopores is crucial to the successful application of numerous recently developed novel templated microporous and mesoporous materials. This project seeks to extend a new theory developed by the applicants for single component transport in cylindrical mesopores, to cylindrical micropores as well as to multicomponent adsorbates, in conjunction with experiments using microporous and mesoporous materials such as M ....Multicomponent Transport in Nanopores. Good understanding of transport mechanisms in nanopores is crucial to the successful application of numerous recently developed novel templated microporous and mesoporous materials. This project seeks to extend a new theory developed by the applicants for single component transport in cylindrical mesopores, to cylindrical micropores as well as to multicomponent adsorbates, in conjunction with experiments using microporous and mesoporous materials such as MCM-41, VPI-5 and AlPO4-5. The outcome will be a powerful new theory for a priori prediction of transport coefficients for multicomponent fluids in nanopores based on molecular level information alone, thereby overcoming the empiricism in existing models.Read moreRead less
