Pressure dependence of liquid iron viscosity from machine-learning molecular dynamics

Kai Luo, Xuyang Long, R. E. Cohen

We have developed a machine-learning potential that accurately models the behavior of iron under the conditions of Earth's core. By performing numerous nanosecond scale equilibrium…

A Piezoelectric Molecular Cocrystal with Unconventional $I ¨ $ -Stacking

Samuel G. Dunning, Aldo Raeliarijaona, Piotr A. GuÅka +4

We demonstrate the crystallization of a polar octafluoronaphthalene (OFN, \OFN)--phthalazine (Phth, \Phth) cocrystal, formed in a 1:2 ratio by slow evaporation. The crystal structu…
