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 ...
The addition of graphene nanoplatelets (GNP) to a paraffin-based solvent, eicosane was performed at various wt.% and subsequently the synthesized GNP/eicosane composites were analyzed by a variety of machines. The characterization of the GNP/eicosane composites was performed by the TPS technique for the measurement of thermal conductivity from 10°C to 35°C. At a wt.% of 10 GNP filler the composite had a thermal conductivity four times that of unfilled ...
The TPS technique was used to measure the thermal conductivity of three different steel samples, which allowed the researchers to analyze the steel critically. Specifically look at was the dependence of thermal conductivity on temperature from room temperature up to 300°C. The obtained results were compared values obtained from other research groups....
The present study look at the creation of unfilled and carbon nanofibre (CNF)-filled polypropylene (PP) foams, and their subsequent testing of thermal and mechanical properties. The testing of thermal properties was accomplished by the TPS Technique and determined that when using up to 20 wt.% CNF as filler there was no increase in thermal conductivity of any of the sample foams. Therefore it was decided that it was the foamed ...
Through the use of the salt-leaching pore forming method, a series of sintered nickel capillary wicks with variable porosity and pore characteristics were synthesized. The thermal conductivities of these wicks (both dry and wet) were evaluated by the transient plane source (TPS) method. The factors that affect thermal conductivity were found to be the porosity and the pore size distribution....
