Anomalies in bulk supercooled water at negative pressure.
Water anomalies still defy explanation. In the supercooled liquid, many quantities, for example heat capacity and isothermal compressibility κT, show a large increase. The question arises if these quantities diverge, or if they go through a maximum. The answer is key to our understanding of water anomalies. However, it has remained elusive in experiments because crystallization always occurred ...
متن کاملStructure of supercooled and glassy water under pressure.
We use molecular-dynamics simulations to study the effect of temperature and pressure on the local structure of liquid water in parallel with neutron-scattering experiments. We find, in agreement with experimental results, that the simulated liquid structure at high pressure is nearly independent of temperature, and remarkably similar to the known structure of the high-density amorphous ice. Fu...
متن کاملAnomalies of Bulk , Nanoconfined and Protein - Hydration Water
Anomalous behavior of water has been a long standing problem in physical and chemical sciences. The seeming divergence of response functions such as specific heat, compressibility, and coefficient of thermal expansion at low temperatures T , have been interpreted by some authors as the evidences for the liquid-gas spinodal retracing back to positive pressures P at low temperatures. Other author...
متن کاملExploring water and other liquids at negative pressure.
Water is famous for its anomalies, most of which become dramatic in the supercooled region, where the liquid is metastable with respect to the solid. Another metastable region has been hitherto less studied: the region where the pressure is negative. Here we review the work on the liquid in the stretched state. Characterization of the properties of the metastable liquid before it breaks by nucl...
متن کاملNature of the anomalies in the supercooled liquid state of the mW model of water.
The thermodynamic properties of the supercooled liquid state of the mW model of water show anomalous behavior. Like in real water, the heat capacity and compressibility sharply increase upon supercooling. One of the possible explanations of these anomalies, the existence of a second (liquid-liquid) critical point, is not supported by simulations for this model. In this work, we reproduce the an...
