Modeling of liquid internal energy and heat capacity over a wide pressure–temperature range from first principles (2020)
Journal Article
Proctor, J. (2020). Modeling of liquid internal energy and heat capacity over a wide pressure–temperature range from first principles. Physics of Fluids, 32, 107105. https://doi.org/10.1063/5.0025871

Recently, there have been significant theoretical advances in our understanding of liquids and dense supercritical fluids based on their ability to support high frequency transverse (shear) waves. Here, we have constructed a new computer model using... Read More about Modeling of liquid internal energy and heat capacity over a wide pressure–temperature range from first principles.

The liquid and supercritical fluid states of matter (2020)
Book
Proctor, J. (2020). The liquid and supercritical fluid states of matter. CRC Press (Taylor and Francis). https://doi.org/10.1201/9780429491443

This book addresses graduate students and researchers wishing to better understand the liquid and supercritical fluid states of matter, presenting a single cohesive treatment of the liquid and supercritical fluid states using the gas-like and solid-l...

Raman spectroscopy of ethane (C 2 H 6 ) to 120 GPa at 300 K (2020)
Journal Article
Read, L., Spender, J., & Proctor, J. (2020). Raman spectroscopy of ethane (C 2 H 6 ) to 120 GPa at 300 K. Journal of Raman Spectroscopy, 51(11), 2311-2317. https://doi.org/10.1002/jrs.5971

We have conducted a Raman study of solid ethane (C2H6) at pressures up to 120 GPa at 300 K. We observe changes within the ν3 and ν11 Raman‐active vibrational modes providing evidence for several previously unobserved phase transitions at room tempera...

Experimental and theoretical confirmation of an orthorhombic phase transition in niobium at high pressure and temperature (2020)
Journal Article
Errandonea, D., Burakovsky, L., Preston, D., MacLeod, S., Santamaría-Perez, D., Chen, S., …Mezouar, M. (2020). Experimental and theoretical confirmation of an orthorhombic phase transition in niobium at high pressure and temperature. communications materials, 1, 60. https://doi.org/10.1038/s43246-020-00058-2

Compared to other body-centered cubic (bcc) transition metals, Nb has been the subject of fewer compression studies and there are still aspects of its phase diagram which are unclear. Here, we report a combined theoretical and experimental study of N...
