The movement of small water droplets is controlled by means of a magnet
magnet water movement magnetic field
2021/8/11
A new study has presented and characterized the formation and properties of a superparamagnetic ring, which fits snugly around a drop of water due to liquid-liquid interaction, and allows the drops to...
vdW-DF Study of energetic, structural, and vibrational properties of small water clusters and ice Ih
vdW-DF small water clusters ice Ih
2011/9/15
We present results for a density functional theory study of small water clusters and hexagonal ice Ih, using the van der Waals density functional (vdW-DF). In particular, we examine energetic,structur...
Study on radon and radium concentrations in drinking water in west region of Iran
Radon concentration Drinking water cancer risk lung dose Stomach dose
2011/9/2
One of the most important characterizations of social health is existence the availability of safe drinking water. Since one of the sources of water contamination is nuclear contamination from radon g...
Trace Element Concentration in São Francisco River Water Using STXRF and PIXE Techniques
Trace Element Concentration Sã o Francisco River Water STXRF and PIXE Techniques
2010/10/15
Trace element concentrations in water from S˜ao Francisco River using Particle Induced X-ray Emission (PIXE) and Synchroton Total Reflection X-ray Fluorescence (STXRF) techniques are measured. Th...
Computer Simulation of Dynamical Anomalies in Stretched Water
Computer Simulation Dynamical Anomalies Stretched Water
2010/10/18
In this work, we describe how the anomalous diffusivity is related to the structural anomalies. For this purpose, we study how the thermodynamics and the dynamics of low-temperature water are affected...
Detection of Water by Neutron Scattering Using a Small Plasma Focus
Water Neutron Scattering a Small Plasma Focus
2010/10/27
A compact Plasma Focus operated in deuterium which produces 2 108 neutrons per pulse, has been used as a radiation source for water detection by neutron scattering. The detecting system is composed by...
Clustering of Dust Particles on Water Surface
Dust Particles Water Surface a liquid surface
2010/10/19
In this work we use molecular dynamics simulation to study the clustering of dust particles deposited on a liquid surface. Our results are compatible with the picture that one particle attracts anothe...
The Proton Momentum Distribution in Water and Ice
The Proton Momentum Distribution Water Ice
2010/10/18
Deep Inelastic Neutron Scattering (Neutron Compton Scattering), is used to measure the momentum distribution of the protons in water from temperatures slightly below freezing to the supercritical phas...

Simple Explicit Water Models the Simulations of Biomolecules
2010/10/18
Computer simulations of biomolecular systems have achieved a significant importance in science as they provide information regarding structure, dynamics, and energetics of biomolecules that are inacce...
The Water Factor in the Protein-Folding Problem
The Water Factor the Protein-Folding Problem
2010/10/18
Globular proteins are produced as a linear chain of aminoacids in water solution in the cell and, in the same aqueous environment, fold into their respective unique and functional native structures. I...
Dielectric Constant and Density of Water as a Function of Pressure at Constant Temperature
Water Constant Temperature Dielectric Constant Density of Water
2010/10/18
In order to simulate the effects of hydrostatic pressure on protein folding/unfolding it is necessary to accurately describe the behavior of the dielectric constant and the density of the solvent (wat...
Hydrogen bonded liquids like water present a rich thermodynamic behaviour due to the strength and directionality of the bonds. In a recent paper a geometric model based on Bernal’s model for liquids w...
The Interpretation of Water Anomalies in Terms of Core-Softened Models
Water Anomalies Core-Softened Models
2010/10/18
In the first part of this paper I review the understanding of anomalous properties of water in terms of particles interacting by core-softened potentials. I discuss the origin of the bulk anomalies in...
