Dielectric Properties of Foods
Turkish Journal of Agriculture - Food Science and Technology, 2019 Dielectric properties of materials are used for evaluating their interactions with electromagnetic energy. Dielectric properties of food materials are required for various applications in food industry such as microwave (at 915 or 2450 MHz), radio wave (at 13.56, 27.12 or 40.68 MHz) and magnetic field processing.

Dielectric properties of nanosized ZnFe2O4
Processing and Application of Ceramics, 2008 In this paper we present the results concerning the dielectric properties of the nanosized ZnFe2O4. Dielectric permittivity, the loss factor, as well as the conductivity, were measured in the temperature range 300-630 K and at 1 Hz, 10 Hz, 100 Hz, 1 kHz and 10 kHz frequencies.

Dielectric properties of epoxy nanocomposites [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2008 The dielectric properties of epoxy nanocomposites with insulating nano-fillers, viz., TiO2, ZnO and AI2O3 were investigated at low filler concentrations by weight. Epoxy nanocomposite samples with a good dispersion of nanoparticles in the epoxy matrix were prepared and experiments were performed to measure the dielectric permittivity and tan delta (400

Dielectric properties of semicrystalline polychlorotrifluoroethylene
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1962 The dielectric properties of polychlorotrifluoroethylene (T(m) = 224 °C, T(g) = 52 °C) have been measured at temperatures between −50 and +250 °C, and at frequencies between 0.1 c/s and 8.6 kMc/s. Specimens of known crystallinities, ranging from χ = 0.80 to χ = 0.00 (pure liquid) were studied. Comprehensive tables of data are presented.

Dielectric and dielectrophoretic properties of DNA
IET Nanobiotechnology, 2009 The physical properties of DNA are quite important for molecular genetics as well as for its nanotechnological applications. Studying the interactions of alternating current (AC) electric fields with deoxyribonucleic acid (DNA) allows one to draw conclusions about these properties. These interactions are usually investigated in two different ways.

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.

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
