Microstructural and thermophysical properties of Uā€“6 wt.%Zr alloy for fast reactor application

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....

High thermoelectric performance in Bi2-xPbxBa2Co2Oy promoted by directional growth and annealing

The laser floating zone method was used to prepare Pb doped Bi2-xPbxBa2Co2Oy thermoelectric materials with x=0, 0.2, 0.4, and 0.6. The highest power factor reported was obtained at 650oC for the 0.2 Pb doped samples. This value was higher than that for pure laser grown Bi2Ba2Co2Oy materials. The thermal conductivity was decreased, as is desired in thermoelectric materials....

A comprehensive characterization on the structural and thermophysical properties of sintered ore particles toward waste heat recovery applications

Thermophysical and structural properties of sintered ore particles (SOPs) were determined to expand upon the little documented information there is regarding the properties of these materials. In addition to this, a fractal model was also developed for the prediction of thermal conductivity in SOPs as a function of porosity. The experimental results revealed that the specific heat capacity increased with increasing temperature and that the thermal conductivity decreased with increasing ...

High thermoelectric figure-of-merit in p-type nanostructured (Bi,Sb)2 Te3 fabricated via hydrothermal synthesis and evacuated-and-encapsulated sintering

A series of Bi(2-x)Sb(x)Te3 powders were prepared via hydrothermal methods by varying x (x=1.45, 1.50, 1.55, 1.56). These powders were then heavily characterized by XRD, EDS, ICP-AES, TEM, SEM and the TPS technique. A low thermal conductivity was desired, so as to give the highest thermoelectric figure of merit (ZT). It was determined that the highest figure of merit was obtained when x=1.55, which resulted in a value of 1.65 ...

Thermal Properties of the Hybrid Graphene-Metal NanoMicro-Composites: Applications in Thermal Interface Materials

As electronic devices become smaller, power densities increase and so do hotspot temperatures, leading to a need for materials that can exchange heat better. The materials that facilitate this heat exchange are called thermal interface materials (TIMs). Graphene has been shown to demonstrate superior thermal conductivity and a particular form called few-layer graphene (FLG) was used in this project. A novel TIM was created by the mixing of a silver ...
