High-temperature water (HTW), which we define broadly herein as liquid water above 200 C
and supercritical water (T> 374 C, P> 218 atm), is attracting attention as a medium for …

Water is a truly unique substance in many respects. It is the only chemical compound that
naturally occurs in all three physical states (solid, liquid and vapor) under the …

Due to its ubiquity in our environment (near or far remote) water is the most investigated
liquid of the literature. Since the advent of molecular simulations in the sixties the key point …

The properties of hydrogen bond networks in ambient, supercritical, and stretched model
water at temperatures between 573 K and 873 K and densities between 0.1 g/cm3 and 1 …

The Raman spectra of water are measured at temperatures up to 510° C and at pressures
up to 40 MPa. The peak frequency increases with temperature, indicating the break of …

Due to its key role in environmental sciences, biology, and industrial technology, water is, by
far, the most widely studied liquid by computer simulation. In spite of this, and curiously …

We present a first-principles molecular dynamics study of water near and above the critical
point (T= 647 K, ρ= 0.32 g/cm 3). We find that the systems undergo fast dynamics with …

A high-pressure and high-temperature FTIR was used to study noncatalytic Beckmann and
pinacol rearrangements using supercritical water (scH2O). Significant acceleration of …

Abstract Thinking about water is inextricably linked to hydrogen bonds, which are highly
directional in character and determine the unique structure of water, in particular its …

The pressure-driven collapse in the structure of network-forming materials will be
considered in the gigapascal (GPa) regime, where the development of in situ high-pressure …
