Studies of Electrical Moment and thermodynamic properties of water in organic solvents at 298.15 K
Journal of Molecular Liquids, 2007Co-Authors: Rahul R. Kolhapurkar, Dilip H. Dagade, Kesharsingh J. Patil, Murlidhar KaulgudAbstract:Abstract We report in this paper on measurements of static dielectric constant (e) at 1 kHz for solutions of water dissolved in organic solvents (benzene and 1,4-dioxane) of low dielectric constant at 298.15 K. The solutions having different water activities and hence concentrations were prepared by isopiestic technique. The solubility data indicate validity of Henry's law only near solutions of unit water activity. The variation of e with concentration of water is subjected to analysis using the Kirkwood–Frohlich equation. The calculated dipole Moment values (μ) for water molecules indicate presence of monomers in 1, 4-dioxane solutions while μ values in case of the H2O–benzene system reveal change of monomer to cyclic-trimer species. Also, an attempt is made to apply McMillan–Meyer theory to the data of the H2O–benzene system. The results of these indicate presence of pair and triplet interactions (osmotic virial coefficients) for water molecules in the condensed phase.

Magnetic Moment Quadric of Rotational Charged Body and Its Condition of Zero Magnetic Moment
Journal of Wuhan University, 2008Co-Authors: Zhou Guo-quanAbstract:Based on the property of the Electrical Moment tensor (which is different from the existent electric multiple Moment) of a charged body, new concepts such as principal axes, principal-axis scalar charge Moment and charge Moment quadric are proposed in this paper. According to the linear relationship between the scalar charge Moment and the magnetic Moment of a rotational charged body, by means of analytic spatial geometry, the criterion formulae determining the correspondence relationship between quadric distributive laws of magnetic Moment and the parameters of tensor are obtained and classified in detail in a table. The condition of zero magnetic Moment for an arbitrary rotational body with given charge distribution has been derived. We conclude that any rotation axis which passes through origin O and along with any asymptotic line of the quadric (hyperboloids or hyperbolic cylinders, etc.) can lead to a vanishing magnetic Moment.
