In-situ Microwave-assisted Catalytic Upgrading of Heavy Oil: Experimental Validation and Effect of Catalyst Pore Structure on Activity (2020)
Journal Article

In-situ combustion alone may not provide sufficient heating for downhole, catalytic upgrading of heavy oil in the Toe-to-Heel Air Injection (THAI) process. In this study, a new microwave heating technique has been proposed as a strategy to provide th...

Predicting Surface Diffusivities of Gas Molecules in Shale (2020)
Journal Article

Carbon dioxide injection can be utilized as a means of both enhancing gas recovery from shales and sequestering carbon and thereby simultaneously addressing the growing worldwide gas demand, as well as the challenge of greenhouse gas emissions. Great... Read More about Predicting Surface Diffusivities of Gas Molecules in Shale.

Hyperpolarised xenon MRI and time-resolved X-ray computed tomography studies of structure-transport relationships in hierarchical porous media (2020)
Journal Article

© 2020 Elsevier B.V. Catalysed diesel particulate filter (DPF) monoliths are hierarchical porous solids, as demonstrated by mercury porosimetry. Establishing structure-transport relationships, including assessing the general accessibility of the cata...

Structural and chemical heterogeneity in ancient glass probed using gas overcondensation, X-ray tomography, and solid-state NMR (2020)
Journal Article

Rare ancient glasses have complex, multi-scale structures requiring more sophisticated and non-destructive pore characterisation techniques than usual. Homotattic patch models for nitrogen adsorption gave better fits to the isotherm data, more accura...
