The a-c. conductivity is calculated for high temperature air as a function of gas temperature (300–12,000° K), gas density (1 to 103 times atmospheric), angular radio frequency, and cyclotron frequency. It is shown that the simple conductivity matrix applies between 6000–8000° K, ...
SUMMARY Electrical conductivity at five different temperatures was measured for the saturation extracts of 30 samples of saline and alkali soils from Colorado, Idaho, Oregon, Washington, and India. For this group, the average per cent ch... RB Campbell,CA Bower,LA Richards - 《Soil Science Soci...
A decrease in iron's thermal conductivity with increasing temperature is not observed in Campo del Cielo (IAB) and is the only iron to be measured at two different temperatures. Campo del Cielo has a reported conductivity of 22.4 W/(m-K) at 200K and of 52 W/(m-K) at 300K (...
Convection involves movement of a heated fluid, such as air, usually a fairly rapid process. Radiation refers to the transmission of energy as electromagnetic radiation from its emission at a heated surface to its absorption on another surface, a process requiring no medium to convey the energy....

The AC electrical conductivity is one of the most significant properties of materials, allowing to determine the electrical conduction mechanism. The variation in conductivity as a function of frequency at different temperatures for the (NPTe) compound is portrayed in Figure 13. The values of σac...
The diffusion barrier was calculated via Arrhenius fitting of the diffusivity at different temperatures. The activation barrier of local hopping was calculated from the Arrhenius fitting of the local hopping amounts at different temperatures. The local hopping amounts were calculated by counting the ...
the increase of the heating temperature of GeO2impurity precursor will enhance the supplying dose of GeO2and evidently change the shape of h-BN domains. At a low temperature of 600 °C, the triangular-shaped h-BN domains show curved edges and blunt angles, which are different to the norm...
This is important at cryogenic temperatures [6], and for nano-fillers, also at room temperature [7]. Electrically insulating fillers of high thermal conductivity are of particular interest since they can improve the thermal conductivity of the composite material, while maintaining its electrically ...
