Observation of liquid–liquid phase transitions in ethane at 300 K (2018)
Journal Article
Proctor, J., Bailey, M., Morrison, I., Hakeem, M., & Crowe, I. (2018). Observation of liquid–liquid phase transitions in ethane at 300 K. Journal of Physical Chemistry B, 122(44), 10172-10178. https://doi.org/10.1021/acs.jpcb.8b07982

We have conducted Raman spectroscopy
experiments on liquid ethane (C2H6) at 300 K, obtaining a
large amount of data at very high resolution. This has enabled
the observation of Raman peaks expected but not previously
observed in liquid ethane and... Read More about Observation of liquid–liquid phase transitions in ethane at 300 K.

Electric discharge machine for preparation of diamond anvil cell sample chambers (2018)
Journal Article
Proctor, J., & Massey, D. (2018). Electric discharge machine for preparation of diamond anvil cell sample chambers. Review of Scientific Instruments, 89(2018), #105109. https://doi.org/10.1063/1.5050500

We have designed and constructed a novel electric discharge machine designed primarily for the preparation of sample chambers in rhenium and stainless steel gaskets for diamond anvil cell experiments. Our design combines automatic stage movement with... Read More about Electric discharge machine for preparation of diamond anvil cell sample chambers.

High pressure Raman, optical absorption, and resistivity study of SrCrO4 (2018)
Journal Article
Hakeem, M., Jackson, D., Hamlin, J., Errandonea, D., Proctor, J., & Bettinelli, M. (2018). High pressure Raman, optical absorption, and resistivity study of SrCrO4. Inorganic Chemistry, 57(13), 7550-7557. https://doi.org/10.1021/acs.inorgchem.8b00268

We studied the electronic and vibrational properties of monazite-type SrCrO4 under compression. The study extended the pressure range of previous studies from 26 to 58 GPa. The existence of two previously reported phase transitions was confirmed at 9... Read More about High pressure Raman, optical absorption, and resistivity study of SrCrO4.

Liquid mysteries (2018)
Journal Article
Proctor, J. (2018). Liquid mysteries. Physics world, 31(5), https://doi.org/10.1088/2058-7058/31/5/37

It's easy to assume there's nothing new to learn about liquids. John Proctor explains just how weird liquids can be at high pressures and why this work could shed light on planetary interiors.

Dynamics, thermodynamics and structure of liquids and supercritical fluids : crossover at the Frenkel line (2018)
Journal Article
Fomin, Y., Ryzhov, V., Tsiok, E., Proctor, J., Prescher, C., Prakapenka, V., …Brazhkin, V. (2018). Dynamics, thermodynamics and structure of liquids and supercritical fluids : crossover at the Frenkel line. Journal of Physics: Condensed Matter, 30(13), #134003. https://doi.org/10.1088/1361-648X/aaaf39

We review recent work aimed at understanding dynamical and thermodynamic properties of liquids and supercritical fluids. The focus of our discussion is on solid-like transverse collective modes, whose evolution in the supercritical fluids enables one...
