This article describes comprehensive testing performed to increase understanding of how the thermal conductivity of ceramic fibers is affected. Non fibrous material content, temperature, and pressure were the main parameters investigated. Three different ceramic fiber samples were used in the research. Researchers discovered that the incorporation of aluminum reduced the thermal conductivity and consequently improved the insulation performance of the sample. An increase in pressure increased the thermal conductivity of ...
The purpose of this article was to investigate the thermal performance of light steel structures. Responsible and sustainable building practices are becoming the norm, and light steel can provide a good alternative to other construction materials. However, it is important that the finished building has good thermal management characteristics to reduce energy consumption. The authors of this study looked at the thermal characteristics of buildings fabricated from a combination of ...
Pristine and modified exfoliated graphite nanoplatelets (xGnPs and M-xGnPs, respectively) were dispersed into a paraffin wax phase change material (PCM) in an effort to raise the thermal conductivity of the PCM. The addition of pure xGnPs would decrease the electrical resistivity of the composite PCM, and thus its potential for use in electrical devices would be limited due to safety concerns. To eliminate this issue, the M-xGnPs were prepared. Samples ...
The thermoelectric properties of the co-doped misfit-layered cobaltites of Ca3-xAgxCo3.95Fe0.05O9+delta (x=0.0, 0.1, 0.2, 0.3) were investigated at temperatures between 300 and 700 K. It was found that the thermopower increased with increasing temperature. The thermal conductivity was found to increase with increasing Ag+ content in the samples, and the highest calculated figure of merit was determined for the Ca2.8Ag0.2Co3.95Fe0.05O9+delta....
The influence of In content in the Se98-xAg2Inx (x = 0, 2, 4, 6) system of chalcogenide glasses on the physical properties of the glasses were investigated by the authors. The maximum thermal conductivity and thermal diffusivity value was observed for the sample containing 2 at. % In. The microhardness was found to initially decrease upon doping of In for Se; however, it began to slowly increase after a certain In content had been attained. ...
