Thermal properties of Ca3xDyxCo3.95Ga0.05O9+d were quantified, as were the thermoelectric properties. X-ray diffraction was used to determine the phase of the samples. The thermopower of all samples was determined to be positive. The figure of merit and the power factor increased for the samples after doping had occurred....
Wood is still commonly used to produce window frames in many parts of the world. In this application the orientation of the wood is very important, as its anisotropic properties mean that heat loss could be greatly influenced by how the piece is cut. Manufacturers must ensure that the wood is oriented in a way that the least amount of heat will be lost to the outside through the frame. ...
The effect of a titanate coupling agent on the thermal conductivity of talc filled high density polyethylene. Moisture content and mechanical properties were studied in addition to thermal conductivity. Samples with and without the isopropyl tri(dioctyl)phosphate titanate were investigated. Thermal conductivity did not change with the addition of the coupling agent, however the stiffness and tensile strength of the samples did increase....
This article studied the thermal conductivity of samples of autoclaved aerated concrete with various densities at high temperatures in order to produce data that could be used to assess and predict the performance of buildings during a fire. The mica sensor was employed for high temperature measurements. The values obtained by the authors experimentally were then compared against the reference values provided by national and international standards for high temperature ...
This article described an experimental set up using the TPS instrument and a high pressure vessel to enable researchers to accurately measures the thermal conductivity of metal hydrides as a function of pressure. Metal hydrides have promise in applications of hydrogen storage in the auto industry, however a better understanding of their thermal properties is required. The authors investigated thermal conductivity, diffusivity, specific heat and thermal contact resistance. Experimental trials ...
