Application of nanoparticle tracking analysis platform for the measurement of soot-in-oil agglomerates from automotive engines (2013)
Journal Article
La Rocca, A., Di Liberto, G., Shayler, P., Parmenter, C., & Fay, M. (2014). Application of nanoparticle tracking analysis platform for the measurement of soot-in-oil agglomerates from automotive engines. Tribology International, 70, 142-147. https://doi.org/10.1016/j.triboint.2013.09.018

Nanoparticle Tracking Analysis (NTA) has been applied to characterising soot agglomerates of particles and compared with Transmission Electron Microscoscopy (TEM). Soot nanoparticles were extracted from used oil drawn from the sump of a light duty au...

Paramagnetic, near-infrared fluorescent Mn-doped PbS colloidal nanocrystals (2013)
Journal Article
Turyanska, L., Moro, F., Knott, A. N., Fay, M. W., Bradshaw, T. D., & Patanè, A. (2013). Paramagnetic, near-infrared fluorescent Mn-doped PbS colloidal nanocrystals. Particle and Particle Systems Characterization, 30(11), https://doi.org/10.1002/ppsc.201300184

Mn-doped PbS colloidal nanocrystals in aqueous solution are paramagnetic and optically active in the technologically important biological window between 1.2 and 0.8 μm. Cytoxicity studies show that exposure of human cell lines to the nanoparticles at... Read More about Paramagnetic, near-infrared fluorescent Mn-doped PbS colloidal nanocrystals.

TEM study on the electrical discharge machined surface of single-crystal silicon (2013)
Journal Article
Murray, J., Fay, M., Kunieda, M., & Clare, A. (2013). TEM study on the electrical discharge machined surface of single-crystal silicon. Journal of Materials Processing Technology, 213(5), https://doi.org/10.1016/j.jmatprotec.2012.11.028

EDM is a useful process for machining high-aspect ratio features with good accuracy in electrically conductive materials irrespective of their mechanical properties. With the ability of micro-EDM to compete with the resolution of conventional semi-co... Read More about TEM study on the electrical discharge machined surface of single-crystal silicon.

Band-gap profiling by laser writing of hydrogen-containing III-N-Vs (2012)
Journal Article
Balakrishnan, N., Pettinari, G., Makarovsky, O., Turyanska, L., Fay, M. W., De Luca, M., Polimeni, A., Capizzi, M., Martelli, F., Rubini, S., & Patanè, A. (2012). Band-gap profiling by laser writing of hydrogen-containing III-N-Vs. Physical review B: Condensed matter and materials physics, 86(15), Article 155307. https://doi.org/10.1103/PhysRevB.86.155307

We show that the dissociation of the N-H complex in hydrogenated III-N-Vs can be laser activated at temperatures that are significantly smaller than those (>200°C) required for thermal dissociation due to a resonant photon absorption by the N-H compl...
