The effect of pressure on hydrogen solubility in Zircaloy-4 (2019)
Journal Article
Weekes, H. E., Dye, D., Proctor, J. E., Smith, D., Simionescu, C., Prior, T. J., & Wenman, M. R. (2019). The effect of pressure on hydrogen solubility in Zircaloy-4. Journal of Nuclear Materials, 524, 256-262. https://doi.org/10.1016/j.jnucmat.2019.07.012

The effect of pressure on the room temperature solubility of hydrogen in Zircaloy-4 was examined using synchrotron X-ray diffraction on small ground flake samples in a diamond anvil cell at pressures up to 20.9 GPa. Different combinations of hydrogen... Read More about The effect of pressure on hydrogen solubility in Zircaloy-4.

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., Bull, D. J., Marshall, A. R., Adawi, A. M., Howie, R., Sapelkin, A., Brazhkin, V. V., & 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.-S. 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., Errandonea, D., Smith, D., Joris, O. P. J., Sankaran, A., Weekes, H. E., Bull, D. J., Prior, T. J., Dye, D., Errandonea, 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.

Stabilization of boron carbide via silicon doping (2014)
Journal Article
Proctor, J. E., Bhakhri, V., Hao, R., Prior, T. J., Scheler, T., Gregoryanz, E., Chhowalla, M., & Giulani, F. (2015). Stabilization of boron carbide via silicon doping. Journal of Physics: Condensed Matter, 27(1), Article 015401. https://doi.org/10.1088/0953-8984/27/1/015401

Boron carbide is one of the lightest and hardest ceramics, but its applications are limited by its poor stability against a partial phase separation into separate boron and carbon. Phase separation is observed under high non-hydrostatic stress (both... Read More about Stabilization of boron carbide via silicon doping.
