The nature of the dielectric slab will affect the value of E. Now it is proved from the definition and the equation given below.The charge in external electric field divided by the reduced value of electric field gives us the constant i.e. k , which is the constant for material of the ...
The number of moles of solvent/anhydroglucose unit, nSw, correlates well with solvent molar volume, basicity and dipolarity/polarizability. Swelling is sensitive to cellulose crystallite size, surface area and the presence of its chains in parallel or anti-parallel arrangements. Use of solvatochromic...
crystal quartz by passing through the hydrogen-oxygen flame; Type III glass, on the other hand, is produced by combustion of silicon tetrachloride with the flame. Plasma fusion, which produces Type IV glass, is almost similar to flame fusion, except in which plasma flame is used in this ...
It is stressed that dielectric constant/refractive index (as an indicator of polarizability of ligand) along with coordinate bond length should be examined rather than covalency to grasp the trend of 4f鈥 5d transitions. For this purpose, some useful rules-of-thumb are addressed....
The easy link between the dielectric constant of isotropic media and the molecular polarizability of the constituents, is traditionally given by the Lorentz-Lorenz (LL) relation. The local field concept however upon which this relation is based, needs to be re-examined for highly inhomogeneous syste...
In fact, in the ideal gas approximation, from the Lorentz–Lorenz equation for the molecular polarizability, one actually finds [33,34,35] Δ T gas ( θ ) = ( 0.2 − 0.3 ) mK.17 For the CMB case, this would mean that the interactions of the gas with the CMB photons are so ...
Furthermore, this approach cannot explain why the solubility of water for most ionic salts increases with temperature while the dielectric permittivity decreases [17]. To obtain the electrical stiffness of water molecules (with polarizability volume α′ = 1.47 Å3, ionization potential, or ...
