The compounds, lanthanium chromite, lanthanium magnetite and lanthanium ferric oxide were prepared through sol-gel methods in powdered form, then calcinated, peletized, and sintered at various temperatures. Electrical conductivity of these compounds was measured at various temperatures. The effectiveness of strontium as a dopant on electrical conductivity was also investigated. Electrical condu...

High-energy ion beam irradiation of the polymers is a good technique to modify the properties such as electrical conductivity, structural behaviour and mechanial properties. Polyaniline thin films doped with hydrochloric acid (HCl) were prepared by oxidation of ammonium persulphate. The effect of Swift Heavy Ions irradiation on the electrical and structural properties of polyaniline has been me...

Introduction: There is many ways to assessing the electrical conductivity anisotropyof a tumor. Applying the values of tissue electrical conductivity anisotropyis crucial in numerical modeling of the electric and thermal field distribution in electroporationtreatments. This study aims to calculate the tissues electrical conductivityanisotropy in patients with sarcoma tumors using diffusion tens...

We studied the complex conductivity of regioregular poly 3-hexylthiophene P3HT in the temperature range between 193–333 K −80 °C to 60 °C and in the frequency range from the direct current dc to 12 GHz. The identified relaxation process was investigated by quasielastic neutron scattering QENS . The dielectric loss peak extracted from complex conductivity corresponds to local molecular motions h...

SrO-borovanadate glasses with the nominal composition (V2O5)z(SrO)0.2(B2O3)0.8−z , 0.4 ≤ z ≤ 0.8 were studied by direct current (DC) electrical conductivity, inductively coupled plasma (ICP) spectroscopy, Fourier transform infrared (FT-IR) spectroscopy and X-ray-powder-diffraction (XRD). These glasses were prepared by a normal quench technique and the actual compositions of the glasses were det...

An empirical electrical conductivity assessment of nanofluids comprising CuO nanoparticles water-based in different concentrations, particles size and various temperatures of nanofluids has been carried out in this paper. These experimentations have been done in deionized water with nanoparticles sizes such as 89, 95, 100 and 112 nm and concentrations of 0.12 g/l, 0.14 g/l, 0.16 g/l and 0.18 g/...

Two dielectric relaxation loss peaks associated with oxygen-ion diffusion in the intergrowth Bi2WO6–Bi3TiNbO9sBi5TiNbWO15d bismuth layered ferroelectrics were observed. The activation energy and the relaxation time at infinite temperature, for these two peaks, were determined to be s0.89 eV, 1.3310−13 sd and s0.84 eV, 3.6310−10 sd. The ac impedance spectroscopy indicated that the Bi5TiNbWO15 ce...

Magnetoacoustic tomography with magnetic induction (MAT-MI) is a recently introduced imaging modality for noninvasive electrical impedance imaging, with ultrasound imaging resolution and a contrast reflecting the electrical conductivity properties of tissues. However, previous MAT-MI systems can only image samples that are much more conductive than real human or animal tissues. To image real bi...

We report investigations of functionalized DNA:PEDT-PSS films. The electrical conductivity of the sample material at the room temperature was about (1–5)×10-10 -1cm-1. The IV curves of the samples were linear and symmetrical in the region from the room temperature down to the liquid Nitrogen temperature. The thermal activation energy of the conductivity near the room temperature was about 0.033...
