In this system, the behaviour Ni2+ ions via cyclic voltammetry electromotive force modes heating cooling were It was found that melting temperature passes through minimum at lithium chloride (хLiCl) co...

To study the effect of nano-silica particles on conductivity characteristics ethylene propylene diene monomer (EPDM) insulation, EPDM nanocomposites with different mass fractions nano silica were prepared via melt-blending method. Scanning electron microscopy was used to analyze dispersion nanoparticles in EPDM. Based Fourier-transform infrared spectrum, bonding properties between and analyzed....

Phonon and electron transport in Bi2Te3 has been investigated using a multiscale approach, combining the first-principles calculations, molecular dynamics MD simulations, and Boltzmann transport equations BTEs . Good agreements are found with the available experimental results. The MD simulations along with the Green-Kubo autocorrelation decay method are used to calculate the lattice thermal co...

The temperature dependence of the static electrical conductivity sigma dc (T) a single crystal lanthanum gallium silicate (langasite) La 3 Ga 5 SiO 14 activated with an impurity Mn (1000 ppm) has been studied by impedance spectroscopy. Impedance measurements (sp. gr. P321, Z=1) were carried out along crystallographic axes (double symmetry axis) and c (triple axis). It was found that values || a...

The main objective of the research was to identify semiconducting characteristics mature medium-thick (diameter 14, 15 µm) "Xorazm-150" cotton fibers both undoped and doped with 1.5% aqueous solution KMnO4, including current versus voltage temperature dependence, dependence electrical conductivity, influence doping time on photoconductivity. conducted in range (296-360 K) (0-100 V). infrared sp...

Lanthanum strontium cobalt oxide (LSCO) has been employed as cathode and intercollector materials for solid oxide fuel cells (SOFCs). In the present study, the La0:5Sr0:5CoO3 layer was deposited by atmospheric plasma spray (APS). The effect of heat treatment on microstructure and electrical conductivity of the LSCO deposits was examined. The electrical conductivity of the deposits along the lam...

Meltwater discharge and electrical conductivity were measured in eight 1 3 1 m lysimeters, and snow accumulation and electrical conductivity of melted samples were measured in snow pits during four snowmelt seasons at Mammoth Mountain, California. The peak snow-water equivalent ranged from 0.57 to 2.92 m over the four melt seasons. Lysimeter discharges ranged from 20% to 205% of the mean flow; ...

The structure, conductivity, melting points and caloric effects of the (Li2CO3?Na2CO3?K2CO3)eut melt/MgO nanopowder heterogeneous system with MgO concentration up to 70 vol. % have been investigated. A wide variety methods (DSC, XRD, BET, high resolution scanning electron microscope, AC impedance method, IR Raman spectroscopy) were used evaluate samples research. It is revealed that at values e...

Zn-doped tungsten bronze compounds derived from Ba5CaTi2Nb8O30, with Ba5CaTi2−xZnxNb8O30 composition (x = 0; 0.04 and 0.08) were synthesized by the conventional solid-state reaction route. Both solubility of Zn in Ba5CaTi2Nb8O30 formation P4bm space group verified Rietveld method using X-ray diffraction data. The average crystallite size was order 0.08 µm according to Scherrer's formula. SEM mi...
