Reversible structural transformations in supercooled water from 135 to 245 K

Loni Kringle, Wyatt A. Thornley, Bruce D. Kay +1

Water has many anomalous properties compared to "simple" liquids, and these anomalies are typically enhanced in supercooled water. While numerous models have been proposed, includi…

A New Approach For Learning Coarse-Grained Potentials with Application to Immiscible Fluids

Peiyuan Gao, Xiu Yang, Alexandre M. Tartakovsky

Even though atomistic and coarse-grained (CG) models have been used to simulate liquid nanodroplets in vapor, very few rigorous studies of the liquid-liquid interface structure are…

MARTINI-based Coarse-grained Model for Poly(alpha-peptoid)s

Peiyuan Gao, Alex Tartakovsky

In this paper, we present a new coarse-grained (CG) model for poly (alpha-peptoid)s that is compatible with the MARTINI CG FF. In the proposed model, CG poly (alpha-peptoid) is com…
