different total polarisations shown by the same solute when dissolved in different solvents are to be related to alterations in the orientation polarisations (P) caused by replacement of one dielectric environment by another, the atomic and electronic polarisations being constant throughout such ...
The dielectric constant of water in presence of increasing concentrations of weakly protic solvents depressing the freezing point has been measured. The same measurements have been carried out for various volume ratios between 20°C and the freezing point, as well as in presence of glycine. The co...
as shown by several formulas inSections 4.1 and 4.2. The values of the dielectric constant for several common solvents at 25oC are given inTable 7.2.1. The dielectric constant also depends on temperature. As an example, the variation of the dielectric constant of water as a function of tempe...
For example, pure ice has a dielectric constant of 3.2 and loss factor of 0.003 at 0 °C while liquid water at the same temperature has an ε′ of 79 and an ε″ of 21. As can be seen in Figs. 1 and 2, the higher the moisture content, the more dramatic the change in ...
Computation of dielectric constants of solvent mixtures and electrolyte solutions A general model has been developed for calculating the static dielectric constant of mixed-solvent electrolyte solutions. For mixtures of solvents without ... P Wang,A Anderko - 《Fluid Phase Equilibria》 被引量: 221发...
The dielectric constant values of some protic and aprotic solvents in pure state are presented on the basis of MSA method, perturbation theory and Cluster expansion formulation. The calculations are made on statistical mechanical basis considering the cooperative effect and formation of cluster by H-bo...
Design of Biosolvents Through Hydroxyl Functionalization of Compounds with High Dielectric Constant 来自 Semantic Scholar 喜欢 0 阅读量: 53 作者:G Ou,B He,Y Yuan 摘要: C NMR and H NMR. All the characterization data were consistent with the expected structures. Using conductance measurements, the...
On the other hand, the dielectric constant of acrylic rubber and nitrile rubber is higher than that of silicone rubber. Thus, when acrylic rubber or the like is used for the material of the dielectric film, the electrostatic attraction with respect to the applied voltage increases, compared to...
