The immense potential of colossal permittivity (CP) materials for use in modern microelectronics as well as for high-energy-density storage applications has propelled much recent research and development. Despite the discovery of several new classes of CP materials, the development of such materials with the required high performance is still a highly challenging task. Here, we propose a new el...

The Debye-Hückel theory is probably the most widely used option for counting electrostatic forces in thermodynamic models. This work investigates effects of two important parameters – size ions and relative static permittivity solution. Three different activity coefficient models are analyzed compared 14 salt systems order to have a more complete picture capabilities limitations theory. three b...

recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. in an industrial fermentation of bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. changes in certain plasmid resident properties o...

Abstract Expressions arising from the Bruggeman approach for the homogenization of dielectric–magnetic composite materials, without ignoring the sizes of the spherical particles, are presented. These expressions exhibit the proper limit behavior. The incorporation of size dependence is directly responsible for the emergence of dielectric–magnetic coupling in the estimated relative permittivity ...

This work aimed to the study effect of ethanol ratios on acidity constants bromocresol purple. The BCP were determined in binary mixtures water with containing 0, 30, 40, 50, 60, and 70% (v/v) using spectrophotometric methods. results indicate dependence ratio ethanol. values log10Ka1 log10Ka2 correlated macroscopic (relative permittivity, ε) microscopic Kamlet–Taft parameters (α, β, π*) mixtur...
