The study of dielectric relaxation properties in the binary mixture of polar molecules has been carried out at 25oC temperature for 11 different concentrations using time domain reflectometry technique. The dielectric properties of solute-solvent mixture in the microwave frequency range of 10MHz to 30GHz gives information about the formation of monomers and multimers as well as interaction betw...

The aim of the work was examination of the dielectric properties of a new type of polymer nanocomposites based on PVDF (polyvinylidene fluoride), or a copolymer P(VDF-HFP) with addition of ferrite nanoparticles. The addition of nanofillers leads not only to the formation of polar -phase of PVDF, which shows unique piro-, piezoand ferroelectric properties used in many applications, but also aff...

The detection of local dielectric properties is of great importance in a wide variety of scientific studies and applications. Here, we report a novel method for the characterization of local dielectric distributions based on surface adhesion mapping by atomic force microscopy (AFM). The two-dimensional (2D) materials graphene oxide (GO), and partially reduced graphene oxide (RGO), which have si...

The dielectric properties of plastic resins can play a significant role in the signal performance of high speed, high frequency electrical components. Variations within the plastic material can occur as a result of environmental factors to cause changes to their dielectric properties. The dependency of moisture content and temperature on the dielectric constant and loss tangent of a number of p...

Dielectric properties of mashed potatoes relevant to microwave and radio-frequency (RF) pasteurization and sterilization processes were measured over 1 to 1800 MHz and 20 °C to 120 °C. Effects of moisture content (81.6% to 87.8%, wb) and salt content (0.8% to 2.8%, wb) were investigated. Dielectric loss factors and constants decreased with frequency. Dielectric loss factors increased with tempe...

We report on the synthesis of TbMnO3 nanoparticles by chemical co-precipitation route and their structural, chemical bonding, magnetic and dielectric properties. It is shown that the interesting multiferroic properties of this system as reflected by the concurrent occurrence of magnetic and dielectric transitions are retained in the nanoparticles (size ~40 nm). However, the nanoparticle constit...

Some issues; leakage, tunneling currents, boron diffusion are threatening SiO2 to be used as a good gate dielectric for the future of the CMOS (complementary metal- oxide- semiconductor) transistors. For finding an alternative and novel gate dielectric, the NiO (Nickel oxide) and PVA (polyvinyl alcohol) nano powders were synthesized with the sol-gel method and their nano structural p...
