Journal Article
Filkins, M., Harrison, A., Collier, G. J., Norquay, G., Wild, J. M., Rigby, S. P., Pavlovskaya, G. E., & Meersmann, T. (2024). A standardized MRI phantom for dissolved phase 129Xe MRI. Journal of Magnetic Resonance, 21, Article 100175. https://doi.org/10.1016/j.jmro.2024.100175

Pulmonary MRI of hyperpolarized xenon-129 (hp129Xe) dissolved in the lung parenchyma and vascular phase is gaining increasing attention for clinical assessment of gas exchange in multiple diseases. These conditions can involve thickening of barrier t... Read More about A standardized MRI phantom for dissolved phase 129Xe MRI.

Advancing carbon dioxide capture: investigation into the kinetics and efficiency of absorption in molten calcium oxide-chloride (2024)
Journal Article

Novel THAI well arrangements for improving heavy oil recovery rate in comparison to that achievable in the conventional THAI in situ combustion technology (2024)
Journal Article
Ado, M. R., Greaves, M., & Rigby, S. P. (2024). Novel THAI well arrangements for improving heavy oil recovery rate in comparison to that achievable in the conventional THAI in situ combustion technology. Geoenergy Science and Engineering, 241, Article 213159. https://doi.org/10.1016/j.geoen.2024.213159

The toe-to-heel air injection (THAI) method is an environmentally friendly process for in situ upgrading of heavy oils and bitumen via in situ combustion (ISC). Unlike the conventional ISC that uses a vertical producer, the THAI process uses a horizo...

The world-wide reserves of heavy oil, tar sand, and bitumen, etc., outweigh those of conventional oil by a factor of 7/3. Given that the conventional reserves are being rapidly depleted, the need to develop and produce the unconventional resources ha...

MRI and PFG NMR studies of percolation effects in advanced melting during a cryoporometry characterisation of disordered mesoporous alumina (2024)
Journal Article
Himona, E., Stevens, L., Williams, H., & Rigby, S. P. (2024). MRI and PFG NMR studies of percolation effects in advanced melting during a cryoporometry characterisation of disordered mesoporous alumina. Microporous and Mesoporous Materials, 377, Article 113202. https://doi.org/10.1016/j.micromeso.2024.113202

Cryoporometry (or thermoporometry) offers a way of pore structural characterisation for mesoporous materials that often needs little sample preparation, is relatively quick, and is statistically-representative for macroscopic samples. While it is wel... Read More about MRI and PFG NMR studies of percolation effects in advanced melting during a cryoporometry characterisation of disordered mesoporous alumina.

Do Pores Exist?—Foundational Issues in Pore Structural Characterisation (2024)
Journal Article
