Influence of synthesis conditions on the structure of nickel nanoparticles and their reactivity in selective asymmetric hydrogenation (2019)
Journal Article

Unsupported and SiO2-supported Ni nanoparticles (NPs), were synthesised via hot-injection colloidal route using oleylamine (OAm) and trioctylphosphine (TOP) as reducing and protective agents, respectively. By adopting a multi-length scale structural... Read More about Influence of synthesis conditions on the structure of nickel nanoparticles and their reactivity in selective asymmetric hydrogenation.

Transition from gas-like to liquid-like behavior in supercritical N2 (2019)
Journal Article
Proctor, J., Pruteanu, C., Morrison, I., Crowe, I., & Loveday, J. (2019). Transition from gas-like to liquid-like behavior in supercritical N2. Journal of Physical Chemistry Letters, 10(21), 6584-6589. https://doi.org/10.1021/acs.jpclett.9b02358

We have studied in detail the transition from gas-like to rigid liquidlike behavior in supercritical N2 at 300 K (2.4 TC). Our study combines neutron diffraction and Raman spectroscopy with ab initio molecular dynamics simulations. We observe a narr...

Melting curve and phase diagram of vanadium under high-pressure and high-temperature conditions (2019)
Journal Article
Errandonea, D., Macleod, S., Burakovsky, L., Santamaria-Perez, D., Proctor, J., Cynn, H., & Mezouar, M. (2019). Melting curve and phase diagram of vanadium under high-pressure and high-temperature conditions. Physical Review B, 100(9), https://doi.org/10.1103/PhysRevB.100.094111

We report a combined experimental and theoretical study of the melting curve
and the structural behavior of vanadium under extreme pressure and temperature. We
performed powder x-ray diffraction experiments up to 120 GPa and 4000 K, determining
th... Read More about Melting curve and phase diagram of vanadium under high-pressure and high-temperature conditions.

Viewpoint : graphene is thin, but not infinitely so (2019)
Journal Article
Proctor, J. (2019). Viewpoint : graphene is thin, but not infinitely so. Physics - Spotlighting Exceptional Research, 12, 104-104. https://doi.org/10.1103/Physics.12.104

Atomically thin graphene is considered a prototypical 2D material, but high-pressure experiments now reveal the 3D nature of its mechanical properties.

The effect of pressure on hydrogen solubility in Zircaloy-4 (2019)
Journal Article
Weekes, H., Dye, D., Proctor, J., Smith, D., Simionescu, C., Prior, T., & Wenman, M. (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.
