Physical Review E, 1993
An open question in the study of water concerns the shape of the liquid spinodal line in the phase diagram of water, a boundary which represents the limit of mechanical stability of the liquid state. It has been conjectured that the pressure of the liquid spinodal ${\mathit{P}}_{\mathit{s}}$(T) does not decrease monotonically with decreasing ...

Liquid–Liquid Phase Separation? Ask the Water!
The Journal of Physical Chemistry Letters, 2023Water is more than an inert spectator during liquid-liquid phase separation (LLPS), the reversible compartmentalization of protein solutions into a protein-rich and a dilute phase. We show that LLPS is driven by changes in hydration entropy and enthalpy. Tuning LLPS by adjusting experimental parameters, e.g., addition of co-solutes, is a major goal for

Liquid-liquid transition in ST2 water
The Journal of Chemical Physics, 2012We use the weighted histogram analysis method [S. Kumar, D. Bouzida, R. H. Swendsen, P. A. Kollman, and J. M. Rosenberg, J. Comput. Chem. 13, 1011 (1992)10.1002/jcc.540130812] to calculate the free energy surface of the ST2 model of water as a function of density and bond-orientational order. We perform our calculations at deeply supercooled conditions

Is There a Liquid–Liquid Transition in Confined Water?
The Journal of Physical Chemistry B, 2011Water confined in narrow nanopores that prevent ice crystallization is usually studied as a means to understand the anomalous behavior of bulk liquid water. Nevertheless, there is no agreement on the similarity of the thermodynamics of bulk and nanoconfined liquid water.

Theoretica Chimica Acta, 1992
A Self-Consistent Reaction Field Model is used to study the effect of the molecular environment on the electronic distribution and on the equilibrium geometry of the water dimer in liquid water. Computations are performed at the 6-311G++(2d,2p) MP2 level. Comparison of the results for the monomer and the dimer, in a vacuum and in the liquid, is made in

Physical Biology, 2014
Science and society are failing to grapple with the public health burden of cancer. In this short perspective piece, I contrast reductionism and complexity in cancer research, using water as a simple example, arguing for more 'ecological' approaches to cancer. This is a call to arms to physical scientists, ecologists and others to get involved, to link

Spontaneous liquid-liquid phase separation of water
Physical Review E, 2014We report a molecular dynamics simulation demonstrating a fast spontaneous liquid-liquid phase separation of water and a subsequent slow crystallization to ice. It is found that supercooled water separates rapidly into low- and high-density domains so as to reduce the surface energy in the rectangular simulation cell at certain thermodynamic states ...

A liquid/liquid interface excited by stimulation with water
Journal of Colloid and Interface Science, 2009An immiscible interface, which was composed of CaCl(2) aqueous and ester phases, was excited by the addition of a small amount of water. The excitation, i.e., burst and flow at the interface, was observed above a critical concentration of CaCl(2) in the aqueous phase.

Advances in Computational Studies of the Liquid–Liquid Transition in Water and Water-Like Models
Chemical Reviews, 2018There has been uninterrupted interest in supercooled water ever since the pioneering experiments of Speedy and Angell revealed sharp increases in this substance's response functions upon supercooling. One intriguing hypothesis that was formulated to explain this behavior involves the existence of a metastable liquid-liquid transition (LLT) at deeply ...
