Ceria-coated replicated aluminium sponges as catalysts for the CO-water gas shift process (2020)
Journal Article
Palma, V., Goodall, R., Thompson, A., Ruocco, C., Renda, S., Leach, R., & Martino, M. (2021). Ceria-coated replicated aluminium sponges as catalysts for the CO-water gas shift process. International Journal of Hydrogen Energy, 46(22), 12158-12168. https://doi.org/10.1016/j.ijhydene.2020.04.065

A study on the use of chemical conversion coating as a preparative technique for foam-based structured catalysts, in the water gas shift reaction, is presented. The results showed a significant correlation between the textural properties of the struc...

Mechanical vibration bandgaps in surface-based lattices (2018)
Journal Article
Elmadih, W., Syam, W. P., Maskery, I., Chronopoulos, D., & Leach, R. (2019). Mechanical vibration bandgaps in surface-based lattices. Additive Manufacturing, 25, 421-429. https://doi.org/10.1016/j.addma.2018.11.011

In this paper, the phonon dispersion curves of several surface-based lattices are examined, and their energy transmission spectra, along with the corresponding bandgaps are identified. We demonstrate that these bandgaps may be controlled, or tuned, t... Read More about Mechanical vibration bandgaps in surface-based lattices.

A self-calibration rotational stitching method for precision measurement of revolving surfaces (2018)
Journal Article
Liu, M., Cheung, C., Feng, X., Wang, C., & Leach, R. (in press). A self-calibration rotational stitching method for precision measurement of revolving surfaces. Precision Engineering, https://doi.org/10.1016/j.precisioneng.2018.05.002

When measuring revolving objects, it is often desired to obtain not only the geometrical form of the workpiece, but also the topography of the surface, as they both affect the performance of the part. However, holistic measurement of the entire three... Read More about A self-calibration rotational stitching method for precision measurement of revolving surfaces.

Hierarchical-information-based characterization of multiscale structured surfaces (2018)
Journal Article
Cheung, C. F., Liu, M., Leach, R., Feng, X., & Zhao, C. (2018). Hierarchical-information-based characterization of multiscale structured surfaces. CIRP Annals - Manufacturing Technology, 67(1), 539-542. https://doi.org/10.1016/j.cirp.2018.04.002

© 2018 This paper presents a hierarchical-information-based characterization method for multiscale structured surfaces. The method makes use of a priori information of the multiscale surface and a hierarchical segmentation–registration (HSR) algorith...
