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 ...

Nature, 1924
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 of nanoconfined water
The Journal of Chemical PhysicsThe dielectric function of a dipolar liquid exhibits a strong wavenumber dependence in the bulk homogeneous state. Such a behavior seems to suggest the possibility of a strong system size dependence of the dielectric constant (DC) of a nanoconfined liquid, although details have been revealed only recently.

Dielectric properties of natural media
2006Dielectric, refractive and possibly magnetic properties of the media to be studied with microwave radiometry are important in several ways. First, the absorption coefficient follows from the imaginary part of the refractive index. The refractive index is a simple function of the dielectric constant and of the magnetic permeability.

Dielectric properties of dipolar solids
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1946Abstract A quantitative theory of the dielectric properties of crystalline solids consisting of dipolar long-chain molecules is developed (one dipole per molecule). In these solids the dipoles are concentrated in dipolar planes. In the ground state the dipolar planes have a permanent polarization, but usually the polarizations of ...

Dielectric properties of zwitterionic liquids
The Journal of Chemical PhysicsThe dielectric properties of a series of zwitterionic liquids are thoroughly examined in both the solution and melt states. In dilute solutions, the molar dielectric increment and subsequently derived dipole moment of zwitterionic liquids correlate strongly with the number of linker atoms between the ion pair, following the same trend as previously ...
