The Transient Plane Source (TPS) technique was used to evaluate the thermal transport characteristics (such as thermal conductivity, thermal diffusivity, specific heat per unit volume) in multi-component Se78-xTe20Sn2Pbx glasses at room temperature. From the experimental results, it was noted that thermal conductivity decreased with lead (Pb) content in the ternary Se78Te20Sn<...
In this study, the transient plane source (TPS) technique was used to measure the thermal conductivity and thermal diffusivity of Se85-xTe15Sbx (x = 2, 4, 6, 8, and 10) pellets. These values were then used to determine the specific heat per unit volume of these glasses in the composition range of investigation. It was found that 4 at% of Sb (antimony) results in the critical composition of ...
In this study, variations of thermal properties that depend on the injection molding technique were analyzed. Thermal conductivity was measured using a two-sided a transient plane source method. Results indicate that polytetrafluoroethylene (PTFE) is the most significant raw material on short glass fiber (SGF) and PTFE- reinforced polycarbonate (PC) composites for thermal conductivity. This approach can effectively help in determining the optimal mixture ratio settings for reinforcement under multi-response consideration....
Semiconductor chalcogenide glasses are used in a wide range of applications as solid-state devices, both in scientific and technological fields. In this article, the mechanism of degradation of these materials is studied. The technique was used to measure the variation of thermal conductivity and thermal diffusivity of samples with different exposure times to neutron irradiation. Thermal conductivity and diffusivity increases proportionally with smaller exposure time, while at higher exposure times ...
