A YBa2Cu3O7-delta superconductor was prepared, as well as a version doped with cobalt. These materials were then analyzed using the transient plane source (TPS) technique to determine thermal conductivity. Doping with cobalt resulted in a lower thermal conductivity by a factor of 2....
In 1999 an earthquake ripped through Taiwan, which came to be known as the Chi-Chi earthquake. The authors of this paper drilled into the core of the fault created by the earthquake to recover samples that could be analyzed. Using the transient plane source (TPS) technique, the thermal conductivity and thermal diffusivity of the core samples were measured. The thermal properties were measured in order to give information about frictional heat ...
A series of chalcogenide glasses were prepared by substituting In into Se80Te20 to replace Te. The transient plane source (TPS) technique was then used to measure the thermal conductivity, thermal diffusivity and specific heat of the glass samples. It was determined that the substitution of Te with In caused the thermal conductivity of the sample to increase, although specific heat values remained nearly constant. Specific heat was also determined ...
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 ...
The authors report the synthesis of a novel functionalized graphene sheet (FGS)/silicone porous nanocomposite with varying concentrations of FGS. The physical and thermal properties of the synthesized nanocomposites were studied in depth. SEM and TEM were used to elucidate the physical microstructure of the materials, and the transient plane source (TPS) technique was used to measure thermal conductivity. The nanocomposite showed an increased thermal conductivity as compared to the ...
