Thermophysical properties of a uranium-6 wt. % zirconium alloy were investigated at high temperatures to evaluate the performance of the alloy as a driver fuel for a liquid-metal cooled fast reactor. Of particular interest to the authors were the coefficient of thermal expansion, the specific heat, and the thermal conductivity of the alloy....

The mechanical and thermal properties of blends of cis-polyisoprene (CPI) and trans-polyisoprene (TPI) are investigated and compared to those of the pure elastomers. It was found that the elastic modulus and tensile strength increased with increasing TPI content and that the thermal conductivity, thermal diffusivity, and specific heat of the blends also increased with increasing TPI content. In contrast to this trend, the measured thermal properties of pure TPI were ...

Samples of Ca0.98RE0.02MnO3- delta (RE = Sm, Gd, and Dy) were tested for their thermoelectric and magnetic properties. It was determined that 2% doping at the Ca site with rare-earth elements reduced the electrical resistivity and thermal conductivity in comparison to the undoped material....

The effects of solid phase thermal conductivity, pore thermal conductivity, and pore volume fraction on the measured effective thermal conductivity of porous ceramics with pore volume fractions of 4 to 95% were investigated. The experimental results were then compared with pre-existing numerical models. It was found that the Maxwell-Eucken relation for closed porosity and the Landauer relation for open porosity were able to closely predict the effective thermal conductivity for tin oxide, ...

Molten selenium, silver, cadmium, and tin were used to prepare a-Se, and a-Se98M2 (M = Ag, Cd, and Sn) alloys in order to determine the thermo-physical properties of these materials using the transient plane source technique. In order for these alloys to be used in industrial applications such as phase change optical storage, photo electrochemical solar cells, and holographic recording systems, among others, their thermal transport properties needed to be ...
