The transient plane source (TPS) technique was used for the measurement of thermal properties of superconductors at low temperatures. The superconductors explored include Y123 and Bi2223. One of the main goals of the work was to develop a system where measurements could be made in the temperature range from 84 - 293 K....
Using a combination of transient plane source (TPS) technique and slug calorimetry, 4 commercially available fire resistive materials (FRMs) are studied from room temperature to 1000°C. The materials studied in this report are two gypsum-based and two calcium-silicate based materials. These materials are heterogeneous and thus when heated to elevated temperatures, the microstructure of the materials may be compromised and various reactions and phase changes may take place over the course ...
The authors selected 5 types of softwood species and 5 types of hardwood species that are commonly grown and used for construction in China for thermal analysis. Not only was thermal conductivity measured, but its dependence on moisture content, density and temperature of the wood samples was also investigated. Thermal conductivity was found to increase with increasing density of the wood sample and increasing moisture content. Thermal conductivity was also found to ...
The authors noticed that thermal conductivity was difficult to measure from data recorded in the quasisteady state, which was determined to be caused by ignoring the thermocouple effects in earlier models. The authors then take these thermocouple effects into account and generate a new model for predicting thermal conductivities. Delrin and 304 stainless steel are quantitatively investigated....
A series of compacted Bi0.5Sb1.5Te3 nanoplatelets are synthesized using hydrothermal methods, followed by cold pressing and sintering at temperatures between 300°C and 380°C. A variety of thermal, mechanical and electrical analyses are then performed on the synthesized nanoplatelets including: TPS technique for thermal conductivity, SEM/TEM/AFM to elucidate the mechanical and physical properties of the nanoplatelets, and the Oxford closed cycle cooler cryostat for measurement of electrical ...
