New Computational Approach to Determine Liquid-Solid Phase Equilibria of Water Confined to Slit Nanopores.

Journal of chemical theory and computation

Kaneko T, Bai J, Yasuoka K, Mitsutake A, Zeng XC.
PMID: 26584089
J Chem Theory Comput. 2013 Aug 13;9(8):3299-310. doi: 10.1021/ct400221h. Epub 2013 Jul 03.

We devise a new computational approach to compute solid-liquid phase equilibria of confined fluids. Specifically, we extend the multibaric-multithermal ensemble method with an anisotropic pressure control to achieve the solid-liquid phase equilibrium for confined water inside slit nanopores (with...
