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 thermal conductivity of the PW/nickel foam PCC was enhanced to 1.2 W/m∙K, increasing by a factor of 3 over that of pure PW. Hussain et al. [245,246] compared the cooling performances of lithium batteries with air, pure PW, nickel foam composites, and graphene-coated nickel (GcN...
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...
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 (...
