Dielectric Dispersion

Dielectric dispersion of erythrocyte ghosts.

The underlying mechanism of the low-frequency dielectric dispersion, called the alpha dispersion, of osmotically lysed erythrocytes (erythrocyte ghosts) has remained open since its finding [H. P. Schwan and E. L. Carstensen, Science 125, 985 (1957)]. The alpha dispersion is peculiar to erythrocyte ghosts and has never been observed for intact erythrocytes. Numerical calculation based on interfa...

DIELECTRIC DISPERSION IN SOLUTIONS OF FLEXIBLE POLYMERSt

INTRODUCTION The dielectric properties of polar chain polymers have long1'2 been of great interest to many workers. For solid materials, there is great practical justification for such interest in the sometimes very close relation between mechanical and electrical behaviour, as well as in direct applications to problems of electrical insulation. The study of dielectric constant and loss in dilu...

Dielectric Dispersion Study of Aqueous Solutions

A dielectric measurement for the aqueous solutions at lower frequencies (20Hz to 2MHz) has been carried out in frequency domain using Agilient Precision LCR meter (E4980A). The dielectric permittivity spectra of over entire concentrations with aqueous solutions are measured at 25 ̊C. From observed spectra, static dielectric constants (ε0) have been determined. Dielectric Spectroscopy is especial...

Dispersion Potentials between Atoms and Dielectric Bodies

The theory of van der Waals interaction between an atom and a perfectly reflecting surface has been devel­ oped in the past by several authors for both dielectric and metallic surfaces [1-3]. However, in these early treatments it has always been assumed that the atom is in its ground state. Only recently has the case of excited state potentials been included in the theory [4]. This latter case ...
