We propose a novel method to measure the dielectric constant of insulating liquids using a laser beam. We use a research ellipsometer composed of a laser source, a polarizer, a compensator, a sample holder, an analyzer, and a photo-detector. The laser beam passes through the oil sample and accordingly undergoes polarization changes of its electric vector components; parallel and perpendicular to the...
Series of experiments have shown that when liquid flows over the surface of solid body, both the liquid and the solid body become electrified, mainly because of friction. The quantity of charge and its polarity depends on mutual induction of the two bodies, also on their dielectrical previousness.
Dielectric and Ultrasonic study of tert-butyl alcohol(TBA) and tert-amyl alcohol (TAA) in solution in non-polar solvents is done. The dipole moment is evaluated using ultrasonic velocity and compared with that obtained from dielectric studies. Using free volume, molar volume, the contribution of electronic polarizability, London dispersion forces and dipole dipole interaction are estimated. The non-linear...
Living systems appear to be making use of the whole of the non-ionising electromagnetic spectrum for purposes of information transfer and regulation. Since they operate in an aqueous environment, the dielectric properties of water, lipids, macromolecules and hydrophi1lc-hydrophobic interfaces are also of importance over the whole spectrum.
Values of thermalization ranges bGp were estimated from measured free ion yields using the extended Onsager model in ethene, propene, cyclopropane, propane, n-butane and i-butane at 0.15 ≲ d/dc < 3 (dc = critical fluid density). At d/dc < 0.3 the density normalized range bGpd was (5.5 ± 0.2) 10−6 kg/m2 for the present alkanes and methane and ethane. The double bond in ethene, and the double...
