Gas or liquid? The supercritical behavior of pure fluids

EA Ploetz, PE Smith - The Journal of Physical Chemistry B, 2019 - ACS Publications
By definition, the distinction between a gas and a liquid ceases to exist beyond the critical
point for pure fluids. Nevertheless, there remains a strong desire to attribute gas-like or liquid …

Kirkwood–Buff-derived force field for peptides and proteins: philosophy and development of KBFF20

EA Ploetz, S Karunaweera, N Bentenitis… - Journal of Chemical …, 2021 - ACS Publications
A new classical nonpolarizable force field, KBFF20, for the simulation of peptides and
