Crossover between liquid-like and gas-like behaviour in CH4 at 400 K (2017)
Journal Article
Smith, D., Hakeem, M., Parisiades, P., Maynard-Casely, H., Foster, D., Eden, D., …Proctor, J. (2017). Crossover between liquid-like and gas-like behaviour in CH4 at 400 K. Physical Review E, 96(5), 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., Stokes, J., Viscomi, F., Proctor, J., Gierschner, J., Bouillard, J., & Adawi, A. (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 de... Read More about Determining molecular orientation via single molecule SERS in a plasmonic nano-gap.

Raman spectroscopy of methane (CH4 ) to 165 GPa : effect of structural changes on Raman spectra (2017)
Journal Article
Proctor, J., Maynard-Casely, H., Hakeem, M., & Cantiah, D. (2017). Raman spectroscopy of methane (CH4 ) to 165 GPa : effect of structural changes on Raman spectra. Journal of Raman Spectroscopy, 48(12), 1777-1782. https://doi.org/10.1002/jrs.5237

We have conducted a Raman study of methane (CH4), a major constituent of the outer planets, at pressures up to 165 GPa. We observe splitting of the principal Raman-active vibrational mode above 45 GPa and a nonlinear dependence of Raman peak position...

On the high-pressure phase stability and elastic properties of β-titanium alloys (2017)
Journal Article
and elastic properties of β-titanium alloys. Journal of Physics: Condensed Matter, 29(15), 155401-155401. 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 40GPa, well... Read More about On the high-pressure phase stability and elastic properties of β-titanium alloys.
