Probing water dynamics with OH−
Chemical Physics, 2007Abstract Isotropic Raman spectra of aqueous solutions of LiOH, NaOH and KOH at concentrations ranging from high dilution to saturation have been measured and the frequency and width of the OH − stretching band have been analyzed. The dependence of the bandwidth on solute concentration suggests that the OH − vibration undergoes a transition from ...

Dynamic Heterogeneities in Supercooled Water
The Journal of Physical Chemistry B, 2004We investigate dynamic heterogeneities in liquid water by performing molecular dynamics simulations of the SPC/E model. We find clusters of mobile molecules. We study the temperature and time dependence of the cluster size and find that clusters grow as temperature decreases and have a maximum size at the time scale corresponding to the escape of the ...

An analysis of the results of hydrographic surveys and satellite measurements performed during in roughly the last two decades is presented in order to demonstrate the diversity of manifestations of the mesoscale water dynamics in the coastal zone and in the deep-water part of the Black Sea and the role of mesoscale structures (eddies and jets) in the ...

Water droplet bouncing dynamics
Nano Energy, 2021Abstract Droplet bouncing on surfaces has long been observed in nature and industry, which is rather intriguing and instructive for related technology development. Recent decades have witnessed significant progress on the mechanism exploring, device development, and application demonstrations.

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 ”

Slow Dynamics in Supercooled Water
MRS Proceedings, 1996ABSTRACTWe review some recent results on the self-dynamics in deep supercooled (simulated) water, obtained by analyzing very long Molecular Dynamics simulations. We discuss the possibility of interpreting the observed slowing down of the dynamics in terms of Mode Coupling Theory for supercooled liquids and, at the same time, of associating the ...

Light- and heavy-water dynamics
Physica B: Condensed Matter, 2000Abstract We show first results of an analysis of the dynamics of water as observed by neutron scattering, based on a model common to both isotopic forms, H2O and D2O. Using incoherent scattering results from H2O, and the liquid structure factor of D2O, we show that within the framework of an approximation of decoupled motions, the H2O and D2O spectra

Water dynamics in DMSO–water mixture
Physica B: Condensed Matter, 2000Abstract We study water dynamics in the eutectic DMSO–water mixture by incoherent quasielastic neutron scattering. Water individual motions are modelled by uncoupled whole-molecule translations and rotations around the center of mass. We determine water self-diffusion coefficients, residence times for jump diffusion and rotational relaxation times ...

Chemistry and Technology of Fuels and Oils, 2021
The usual numerical simulation of the oil-water two-phase water cone is difficult to popularize because of its complicated method and the large amount of calculations and data involved. Based on the assumption that oil is supplied horizontally at the outer radius of the oil zone, some simplified water cone calculation methods ignoring the lifting ...
