In an environment that experiences drastically changing temperatures it is potentially more energy efficient to use insulative walls that can change their apparent thermal conductivities. This paper suggests a nano-porous material able to change its thermal conductivity by a factor of 3 varying the pressure upon it from 1 to 100 kPa. Thermal conductivity measurements are made in-situ by an airtight guarded heat flow meter....
This study developed a model that used a transient plane source (TPS) sensor to measure the specific heat capacity of anisotropic materials. The underside of a sample holder with a diameter of 20 mm, and a height of 5 mm was attached to a Kapton TPS sensor. During measurements, the sample holder was hung inside a steel tube at atmospheric pressure. Results showed that the model underestimated the heat capacity, which suggests ...
