studies were carried out on the preparation and properties of the composites made from cellulose acetate butyrate and cellulose acetate propionate with various amounts of barium strontium titanate nano-particle. the nano-particles of barium strontium titanate (bst) with formulation of ba0.77sr0.23tio3 were made by sol-gel method and their purity and particle size were analyzed by x-ray diffract...

The dielectric and relaxation parameters of a binary system of edible oils, containing unsaturated fats namely mustard oil and coconut oil/ground nut oil/linseed oil in different proportions by volume are measured at different frequencies and a constant temperature (40°C). It is realized that at the given temperature, the dielectric constant of prepared samples at microwave frequency increases ...

a simple and reliable method for quick estimation of the dielectric constant of a binary solvent mixture is proposed. the validity of the proposed method has been tested for a broad range of binary solvent mixtures

Clayey soils are the most common material used for water sealing and undertake an important role in controlling landfill-related pollution. Organic liquids can adversely affect the effectiveness of clay liners by drastically increasing their hydraulic conductivity. The aim of this study is to investigate and compare the permeability in two types of clay with different plasticity, exposed to the...

The dielectric and conduction behavior of SrTiO3 thin films deposited on a SrTiO3 single-crystal substrate is studied. Without dc bias, an obvious dielectric ‘‘defect mode’’ in the dielectric loss is observed in the temperature range of ;100–200 K; however, no noticeable corresponding dielectric constant peak is observed. By applying a high dc bias ~>40 kV/cm!, a dielectric constant peak with f...

in this work, we investigated the stability of molybdate-phosphonic acid (mpa) complex by density functionaltheory (dft) computations in six solvents with the dielectric constant ranging from 1.92 to 10.36. the methodsare used for calculations are b3lyp and b3pw9 i that have been studied in two series of basis sets: d95nand6-31+g (d,p) for hydrogen and oxygen atoms; lanl2dz for mo and phosphoru...

The dielectric properties, consisting of the dielectric constant (epsilon') and loss factor (epsilon''), were measured with an open-ended coaxial-line probe and impedance analyzer for uncooked broiler breast muscle pectoralis major and pectoralis minor, deboned at 2- and 24-h postmortem, over the frequency range from 10 to 1,800 MHz at temperatures ranging from 5 to 85 degrees C. The dielectric...
