Journal Article
Pfau, S., La Roca, A., Haffner-Staton, E., Rance, G., Fay, M., Brough, R., & Malizia, S. (2018). Comparative nanostructure analysis of gasoline turbocharged direct injection and diesel soot-in-oil with carbon black. Carbon, 139, 342-352. https://doi.org/10.1016/j.carbon.2018.06.050

Two gasoline turbocharged direct injection (GTDI) and two diesel soot-in-oil samples were compared with one flame-generated soot sample. High resolution transmission electron microscopy imaging was employed for the initial qualitative assessment of t...

Progress towards a methodology for high throughput 3D reconstruction of soot nanoparticles via electron tomography (2018)
Journal Article
Haffner-Staton, E., La Rocca, A., & Fay, M. (2018). Progress towards a methodology for high throughput 3D reconstruction of soot nanoparticles via electron tomography. Journal of Microscopy, 270(3), 272-289. https://doi.org/10.1111/jmi.12680

The aim of this work is to make progress towards the development of 3D reconstruction as a legitimate alternative to traditional 2D characterisation of soot. Time constraints are the greatest opposition to its implementation, as currently reconstruct...

Towards keeping diesel fuel supply and demand in balance: dual-fuelling of diesel engines with natural gas (2016)
Journal Article
Hegab, A., La Rocca, A., & Shayler, P. (2017). Towards keeping diesel fuel supply and demand in balance: dual-fuelling of diesel engines with natural gas. Renewable and Sustainable Energy Reviews, 70, 666-697. https://doi.org/10.1016/j.rser.2016.11.249

With the continuous growth of energy demand for the commercial transport sector, the market share of diesel vehicles is rising in several areas worldwide. Global demand for transport energy is therefore believed to be strongly skewed towards heavier...

Understanding soot nanoparticle interaction with oil additives and the causes of soot-induced thickening would assist in lubricant formulation, prolonging engine life and improving engine efficiency. Three-dimensional measurement of soot structures i... Read More about Soot-in-oil 3D volume reconstruction through the use of electron tomography: an introductory study.

Characterisation of soot in oil from a gasoline direct injection engine using Transmission Electron Microscopy (2015)
Journal Article
