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.

An introduction to graphene and carbon nanotubes (2017)
Book
Proctor, J., Melendrez Armada, D., & Vijayaraghavan, A. (2017). An introduction to graphene and carbon nanotubes. Boca Raton: CRC Press

Carbon nanotubes and graphene have been the subject of intense scientific research since their relatively recent discoveries. This book introduces the reader to the science behind these rapidly developing fields, and covers both the fundamentals and... Read More about An introduction to graphene and carbon nanotubes.
