Dielectric properties of insulin in solution
Physics in Medicine and Biology, 1984Values of the relative permittivity of a 5% solution of despentapeptide insulin (DPI) are given at six temperatures over a frequency range 0.2-50 MHz. The solvent was a mixture of water and ethylene glycol at pH = 3. From the dispersion curves a dipole moment of 72 +/- 1 was obtained for the insulin molecule at 25 degrees C. By combining the dielectric

Dielectric Properties of Zinc Phosphide
physica status solidi (a), 1985The dielectric properties of Zn3P2 crystals are measured in the frequency range 103 to 105 Hz and in the temperature region 300 to 493 K. Samples are prepared by the carbon reduction of zinc orthophosphate. The dielectric dispersion at room temperature and at higher temperatures is attributed to space charge polarisation.

Dielectric properties of phospholipids in chloroform
Chemistry and Physics of Lipids, 1971Abstract Permittivity was studied as a function of temperature and concentration for selected phospholipids in chloroform. Reduced lecithin, egg lecithin, and plant lecithin were used in this study to provide a range of properties in fatty-acid chain composition. In the concentration studies, the nonlinear dependence of permittivity on concentration (

Calculation of the dielectric properties of semiconductors
Physical Review B, 1992We report on numerical calculations of the dynamical dielectric function in silicon, using a continued-fraction expansion of the polarizability and a recently proposed representation of the inverse dielectric function in terms of plasmonlike excitations.

On the Dielectric Properties of a Gas Discharge
Proceedings of the Physical Society. Section B, 1949Formal expressions are derived for the space currents and electrode currents produced by a sinusoidal potential difference of angular frequency ω applied between a pair of electrodes at a distance d apart and immersed in a gas discharge. It is shown that the ionized gas behaves like an isotropic medium of dielectric constant {1 - 4πne2/mω2} and zero ...

Measurement of the Dielectric Properties of Paper
NIP & Digital Fabrication Conference, 1998Unlike de resistivities of non-impact printing papers that are routinely measured, their dielectric properties are seldom considered. The do resistivity alone does not predict the behavior of paper very well when paper passes through a transfer nip. If the electric field changes with time, all anisotropic frequency-dependent electrical properties of ...

As more general interest is now being taken in dielectric actions, it may be useful to give some conclusions derived from a long study of them.

Dielectric properties and oxygenation of hemoglobin
Biopolymers, 1967AbstractDielectric properties of human and horse hemoglobin were studied at frequencies ranging from 20 kc./sec. to 7 Mc./sec. The relative errors in the measurements were usually less than 10−3 even for mildly conducting solutions (10−3M KCl). The experimental setup allowed us variation and measurement of the degree of oxygenation of the protein and ...
