Crossover between liquid-like and gas-like behaviour in CH₄ at 400 K (2017)
Journal Article
Smith, D., Hakeem, M. A., Parisiades, P., Maynard-Casely, H. E., Foster, D., Eden, D., …Proctor, J. E. (2017). Crossover between liquid-like and gas-like behaviour in CH₄ at 400 K. Physical Review E, 96(5), Article 052113. https://doi.org/10.1103/PhysRevE.96.052113

We report experimental evidence for a crossover between a liquid-like state and a gas-like state in fluid methane (CH₄). This crossover is observed in all of our experiments, up to 397 K temperature; 2.1 times the critical temperature of methane. The...

Determining molecular orientation via single molecule SERS in a plasmonic nano-gap (2017)
Journal Article
Marshall, A. R. L., Stokes, J., Viscomi, F. N., Proctor, J. E., Gierschner, J., Bouillard, J. G., & Adawi, A. M. (2017). Determining molecular orientation via single molecule SERS in a plasmonic nano-gap. Nanoscale, 9(44), 17415-17421. https://doi.org/10.1039/C7NR05107G

In this work, plasmonic nano-gaps consisting of a silver nanoparticle coupled to an extended silver film have been fully optimized for single molecule Surface-Enhanced Raman Scattering (SERS) spectroscopy. The SERS signal was found to be strongly dep... Read More about Determining molecular orientation via single molecule SERS in a plasmonic nano-gap.

On the high-pressure phase stability and elastic properties of β-titanium alloys (2017)
Journal Article
Smith, D., Joris, O. P. J., Sankaran, A., Weekes, H. E., Bull, D. J., Dye, D., …Proctor, J. E. (2017). On the high-pressure phase stability and elastic properties of β-titanium alloys. Journal of Physics: Condensed Matter, 29(15), 155401. https://doi.org/10.1088/1361-648x/aa60b6

We have studied the compressibility and stability of different β-titanium alloys at high pressure, including binary Ti-Mo, Ti-24Nb-4Zr-8Sn (Ti2448) and Ti-36Nb-2Ta-0.3O (gum metal). We observed stability of the β phase in these alloys to 40 GPa, well... Read More about On the high-pressure phase stability and elastic properties of β-titanium alloys.
