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 Bi2...
The authors prepared silica aerogel/polyurethane composites by two different methods for the comparison of the two methods. The objective was to study the thermal insulation and hydrophobic properties of the composites to evaluate their potential for use as fabric membranes. It was found that ...
In an effort to enhance heat transfer in the laminar flow regime of a heating duct, TiO2 and SiO2 nanoparticles were added to water to create nanofluids with a higher thermal conductivity than that of the water alone. Twist-tape was also used to enhance heat ...
