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 ...

Dynamical states in liquid water
Journal of Molecular Liquids, 1993Abstract In this paper we present a review of several investigations performed on H 2 O in normal and supercooled phase, by different light scattering techniques. The obtained results give indications of the growth of some extended structure at low temperature and in the supercooled liquid phase. Such phenomenon reflects in the behaviour of a “ slow ”

The Spatial Structure in Liquid Water
Science, 1994Liquid state structure has traditionally been characterized with the radial distribution functions between atoms. Although these functions are routinely available from x-ray diffraction and neutron scattering experiments or from computer simulations, they cannot be interpreted unambiguously to provide the spatial order in a molecular liquid.

Dipolar correlations in liquid water
The Journal of Chemical Physics, 2014We present an analysis of the dipolar correlations in water as a function of temperature and density and in the presence of simple ionic solutes, carried out using molecular dynamics simulations and empirical potentials. We show that the dipole-dipole correlation function of the liquid exhibits sizable oscillations over nanodomains of about 1.5 nm ...

Density Fluctuations in Liquid Water
Physical Review Letters, 2011The density distributions and fluctuations in grids of varying size in liquid water at ambient pressure, both above the freezing point and in the supercooled state, are analyzed from the trajectories obtained from large-scale molecular dynamics simulations.

Ordered structures in liquid water: Is cold water a genuine liquid?
Journal of Raman Spectroscopy, 2022AbstractOrdered structures in liquid water are discussed. Raman spectral changes of water in the temperature range −23°C to 45°C are analyzed with multivariate curve resolution with alternate least squares (MCR‐ALS) and hypothetical addition multivariate analysis with numerical differentiation (HAMAND).

Water adsorption on a liquid surface
Chemical Communications, 2007Monolayer adsorption of water onto an ionic liquid in ultra-high vacuum has been demonstrated, revealing a heat of adsorption which exceeds the heat of absorption into the bulk liquid by approximately 40 kJ mol(-1).

The Liquid Water−Benzene System
The Journal of Physical Chemistry A, 2006The 500 MHz NMR spectra of water-benzene solution near saturation at 303.15, 323.15, and 343.15 K indicate that there is a proton-proton exchange between the water and benzene molecules. In the solution water appears to be present as a dimer attached to the benzene pi cloud on one side of each of the two (initially degenerate) fundamental energy levels,
