Abstract (sommario):

Sand characteristics such as liquefaction susceptibility can be affected as a result of change in degree of saturation of sand. New liquefaction mitigation technique by inducing partial saturation in sands is introduced by Yegian et al in 2007[1]. This technique requires to monitor changes in degree of saturation of sand. By nature, changes in degree of saturation of sand can lead in changes in its electric conductivity. Electric conductivity is the property of a material that represents its ability to conduct electric current. Fully saturated sand can conduct electric current better than sand

AbstractThe electric conductivity is experimentally studied in nanofluids based on water and ethylene glycol containing copper and aluminum particles. Other properties, such as heat conductivity and rheological characteristics, were evaluated as well. The electric conductivity of nanofluids is shown to increase almost linearly with a nanoparticle concentration, but, unlike the heat conductivity, a gain in electric conductivity is due to a decrease in particle size. In this respect, the mechanisms of electric conductivity and heat conductivity are assumed to have the fundamentally different nat

AbstractElectric conductivity tensor of partly-ionized plasma is deduced. Four atmospheric models are used then to estimate the conductivity in the lower atmosphere. The parallel conductivity reaches its minimum value in the temperature minimum zone, which is 1 to 2 orders smaller than the conductivity of fully-ionized plasmas of the same condition; the effective perpendicular conductivity, or Cowling conductivity, becomes 5 to 6 orders smaller than the fully-ionized value in the lower chromosphere.

Abstract The dependence of thermal electric conductivity on temperature in a 1T-FeCl2 monolayer has been explored using the semi-classical Boltzmann transport theory. We provided the temperatures from near critical temperature up to room temperature. We observed different tendencies of thermal electric conductivity based on the existence of magnetism due to working temperature. As we applied the biaxial strain, we obtained the same contribution from both the magnetic and non-magnetic states to the thermal electric conductivity. We also found that the highest thermal electric conductivity may b

Purpose In high-voltage direct current (HVDC) cable systems, space charges accumulate because of the constant applied voltage and the nonlinear electric conductivity of the insulating material. The change in the charge distribution results in a slowly time-varying electric field. Space charges accumulate within the insulation bulk and at interfaces. With an operation time of several years of HVDC systems, typically the stationary electric field is of interest. The purpose of this study is to investigate the influence of interfaces on the stationary electric field stress and space charge densit

Abstract (sommario):

The micro-hardness and electric conductivity was studied in as cast alloy Cu-Fe-P alloys which were solution treated at 980°C and aging treated at 400-800°C for 1-20 hours. The micro-hardness peak value was 180 HV and the conductivity peak value was 65% IACS. The hardness and the electric conductivity all depended on precipitation principally. The addition of C in Cu-Fe-P alloy reduced the grain size and accelerated precipitation which resulted in enhancing hardness and electric conductivity together.

Abstract (sommario):

Carbon foams were prepared by a polymer sponge replication method and their microwave absorbing properties were investigated in this paper. It was found that the electric conductivity of carbon foams increases quickly with the improvement of carbonization temperatures. Moreover, the electric conductivity of carbon foams strongly affects their microwave absorbing performances. As the electric conductivity increases from 0.02 S/m to 1.03 S/m, the dominant electromagnetic behavior of carbon foams changes from transmission to reflection with regard to the incident electromagnetic wave. The best mi

Abstract (sommario):

The main insulation of converter transformers consists of transformer oil and oil-impregnated pressboard. Under operating conditions, the valve-side winding of the converter transformer is subject to DC voltage components. Therefore, studies on the characteristics of oil-impregnated pressboard conductivity are necessary. In this paper, the temperature, moisture and electric field dependency of pressboard conductivity are investigated based on a specially designed three-electrode experimental chamber, which allows for a variation in temperature ranging from 25 °C to 120 °C and an electric field

Abstract (sommario):

Electrorheological (ER) fluids are new materials with good properties such as dielectric constant, dielectric loss or conductivity, which display remarkable rheological behavior, being able to convert rapidly and repeatedly from a liquid to solid when an electric field is applied or removed. In this study, suspensions of alumina (A) were prepared in silicone oil (SO). The effects of electric field strength and temperature of the suspensions on thermal conductivity were determined. Thermal conductivity measurement in different conditions was carried out via experimental instrument with high-vol

Abstract (sommario):

Aluminum nitride ceramics doped carbon nanotubes were fabricated by dispersed multi-walled carbon nanotubes (MWNTs) into AlN powders homogenously. The densification, electric resistance, thermal conductivity and relative dielectric constant of AlN ceramics were investigated. It was found that MWNTs additives could purify the grain boundaries. Furthermore, it induced the increase of the thermal conductivity and the decrease of the relative dielectric constant. However, the linear shrinkage and electric resistance decreased with increasing MWNTs amount. AlN ceramics with high thermal conductivit

Abstract (sommario):

Ferroelectric domain walls differ in their electrical conductivity under different electric and elastic boundary conditions, and this performance can be used to design memories. A phase-field model is developed to explore the effect of elastic, temperature, and toroidal electric fields on the electrical conductivity for a prototype domain-wall memory unit embedded in a center-type quadrant topological domain structure. It shows that the toroidal electric field can switch two states of the domain wall with high and low conductivity repeatedly, and the conductivity can be tuned by the temperatur

Abstract (sommario):

We use numerical simulations to investigate the possibility of enabling steel-cased wells as galvanic sources to detect and quantify spatial variations of electrical conductivity in the subsurface. The study assumes a vertical steel-cased well that penetrates electrically anisotropic horizontal layers. Simulations include a steel-cased vertical well with a finite-length thin wire of piecewise-constant electric conductivity and magnetic permeability. The steel-cased well is energized at the surface or within the borehole at an arbitrary depth with an electrode connected to a current source of v

Abstract (sommario):

The dependence of the conductivity and electric modulus of silver/polyacrylonitrile nanocomposites on the frequency of an alternating electric field has been studied at different temperatures and starting mixture AgNO3 contents. The frequency dependences on the conductivity of the nanocomposites in the range of 103–106 Hz are in good agreement with the power law f0.8. The observed relaxation maxima in the relation of the imaginary part of the electric modulus on the frequency can be explained by interfacial polarization. It was shown that the frequency dispersions of conductivity and electric

A two-dimensional steady convective flow of a micropolar fluid past a vertical porous flat plate in the presence of radiation with variable heat flux has been analyzed numerically. The local similarity solutions for the flow, velocity profile, microrotation and heat transfer characteristics are illustrated graphically for various parameters entering into the problems. The effects of the pertinent parameters on the local skin friction coefficient, plate couple stress and the heat transfer are also calculated.
