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
Rigby, S. P. (2024). Do Pores Exist?—Foundational Issues in Pore Structural Characterisation. Foundations, 4(2), 225-248. https://doi.org/10.3390/foundations4020015

This work reviews a range of fundamental theoretical considerations in pore structural characterisation. The pore concept is essential for providing a better understanding of physical processes arising within porous media than purely phenomenological...

Pore structure-transport relationships in high-temperature shift catalyst pellets studied by integrated multiscale porosimetry and X-ray tomography (2024)
Journal Article
Mousa, S., Beech, T., Softley, E., Fletcher, R. S., Kelly, G., Viney, E., & Rigby, S. P. (2024). Pore structure-transport relationships in high-temperature shift catalyst pellets studied by integrated multiscale porosimetry and X-ray tomography. Chemical Engineering Science, 292, Article 120005. https://doi.org/10.1016/j.ces.2024.120005

Diffusion-limited, heterogeneously-catalysed processes mean choices influencing pore structure-transport relationships, made during pellet fabrication, affect product performance. This work shows how the ‘sifting strategy’ can identify the critical a...
