The dielectric effects on trypsin and a-chymotrypsin activities have revealed that at pH 7.8 the active species of the former is the cation while that of the latter is the anion. The present study on the dielectric effects along the pH-activity curves shows that trypsin remains positive within the pH range of 5.5 to 8.5. Conversely, a-chymotrypsin is positive from pH 5.5 to 6.6, negative from 6...

We define the dielectric constant (susceptibility) that should enter the Maxwell boundary value problem when applied to microscopic dielectric interfaces polarized by external fields. The dielectric constant (susceptibility) of the interface is defined by exact linear-response equations involving correlations of statistically fluctuating interface polarization and the Coulomb interaction energy...

We derive a method for the determination of the dielectric constant and thickness of a thin dielectric layer, deposited on top of a thick dielectric layer which is in turn present on a metal film. Reflection of pand s-polarlzed light from the metal layer yields minima for certain angles of incidence where the light is absorbed by the metal. The thin dielectric layer causes shifts in the angles ...

In this work we have evaluated the dielectric properties of poly vinylidene fluoride (PVDF) thin films of thickness (≈ 20μm) as a function of temperature from 40-70C and frequency varying from 500 Hz to 100 kHz respectively for Al-Al and Cu-Cu electrode configuration. The dielectric constant values increases with the increase in temperature. A broad peak is found at around (70±5)0C. The maximum...
