This study aimed to determine the thermal conductivity of gas-filled Metal Organic Framework (MOF) materials. Glass beads were used as the reference material, and nitrogen (N2) and helium (He) were added to the MOF materials. A TPS instrument measured the thermal conductivity of the MOF samples using the Transient Plane Source (TPS) method. Results showed that the MOF materials containing copper had higher thermal conductivities than iron-filled materials, and the ...
Buildings are responsible for a large portion of the world’s energy use, so there is a high global demand for cost-efficient thermal insulating materials. In this paper, the thermal properties of hollow silica nanosphere nano insulation materials (HSNS NIMs) were examined to test their potential as superinsulating materials. A thermal constants analyzer measured the thermal conductivity of the NIMs using the transient plane source (TPS) method. Results showed that ...
It is important that porous metal foams used in gas turbines do not exceed their upper temperature threshold. In this paper, the Transient Plane Source (TPS) technique was used to measure the thermal conductivity of metal foams up to 1000 °C. Results showed that the thermal conductivity values for porous metal foams were lower than dense metals by a factor of 20-40....
Clathrates are thermoelectric materials that are used in waste heat recovery applications. This study tested the thermophysical properties of the n-doped clathrate Ba8Ga16Ge30 after gallium (Ga) and germanium (Ge) substituted antimony (Sb) and zinc (Zn). A TPS instrument measured the thermal conductivity of n-Ba8Ga16Ge30 with the transient plane source (TPS) method. Results showed that for almost every sample, thermal conductivity decreased inversely to temperature, then increased ...
So far, non-invasive methods that specifically detect abscesses, cracks, and keratomes in horse hooves have yet to be developed. This study used non-invasive Sensors to measure the thermal properties of horse hooves. By using the sensor to heat approximately one square inch of the hoof by 1-2 °C, veterinarians could identify hoof damage based on inconsistent heat conduction. Results of this experiment were reproducible, however more studies need to be ...
