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

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
Development of a Trickle Filter for Treating Sour Water from Oil Shale Processing Plants. Oil is extracted from oil shale by pyrolysing pre-dried crushed shale. Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones.

Despite drying , the shale retains a residual moisture level of approximately 5% which ultimately ends up as an aqueous phase in the condensate stream from the pyrolysis process. This aqueous phase, know as sour water, contains a range of organic compounds, including carboxylic acids, nitorgen heterocyclics and ketones. This aim of this proposal is to develop trickle filters to treat the sour water. The biofilms that develop in trickle filters are ideal for supporting slow growing microbial species. Research is needed to transfer native microorganisms in the oil shale desposit to the durable gravels that will be used in the filter.Read moreRead less

The project aims to generate viscoelastic soft materials with programmable anisotropy using aqueous suspensions of colloidal rods that have tunable surface coatings. The project expects to generate new knowledge in the rheology and structural characteristics of this unique class of materials. A key innovation is the use of charge-directed polymer self-assembly to control colloidal interactions, suspension rheology and phase behaviour. The intended outcome is spatial control over the orientation of nanostructures, potentially mimicking the structural hierarchy found in nature. This should provide significant benefits to the creation of viscoelastic materials with complex rheology as well as structural, mechanical and optical heterogeneity.Read moreRead less
