The authors present a method of producing Cu2CdSnSe4 quaternary nanocrystals using a colloidal synthesis route that could be used for future industrial synthesis. The nanocrystals prepared showed great potential for use as a thermoelectric material due to their high thermoelectric figure of merit (up to 0.71) resulting from a high electrical conductivity and low thermal conductivity. The authors believed that these properties could be further tuned in order to increase ...
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....
The purpose of this study was to develop adhesive epoxy resins that used multiwalled carbon nanotubes (MWCNTs) to enhance thermal conductivity and dispersion in the polymer matrix. An analyzer measured the thermal conductivity of the MWCNTs-based epoxy adhesives using the transient plane source (TPS) method. Results showed that the addition of MWCNTs improved the coefficient of thermal conductivity of the epoxy resin in comparison to pristine epoxy and epoxy (EP)...
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 ...
Although much research had been conducted to improve the ability of engine cylinder heads to respond to thermal stresses, not much research had been conducted on reducing thermal stresses. The authors set out to determine the thermal conductivity of a commercial aluminum 319 type alloy cylinder head with the future goal of improving the thermal conductivity of cylinder heads to better reduce the stress induced by increasing temperature. The cylinders were ...
