Physical Properties of 7-Methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (mTBD)

7-Methyl-1,5,7-triazabicyclo[4,40]dec-5-ene (mTBD) is an important industrial chemical that is commonly used as a catalyst. Prior to the research conducted by Baird et al, the only available data on this chemical pertained to its density and a single vapor pressure value that is provided on chemical safety data sheets. This paper presents the first reliable, publicly available data on the thermodynamic and transport properties of mTBD. These values ...

Thermal effusivity testing with the thermal constants analyzer

The Transient Plane Source method (TPS) simultaneously measures thermal conductivity and thermal diffusivity. This paper investigates the possibilities of using sensors, to record the thermal effusivity of a substrate. With the original method, the thermal effusivity of uniaxial, homogeneous materials in the through-plane direction can be estimated. Tests were performed to analyze the differences in single-sided vs. double-sided testing. For 1-dimensional samples, where heat flow is controlled along the sample, ...

Thermoelectric properties of partly Sb- and Zn- substituted Ba8Ga16Ge30 clathrates

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 ...

Thermal conductivity versus depth profiling of inhomogeneous materials

This research highlights the capabilities of transient measurements and sensors to estimate thermal conductivities of samples with large voids/variations in their compositions. Because of the lack of a physical model to predict thermal conductivity vs depth information of inhomogenous materials, researchers have utilized existing models to create an advanced iteration scheme, to determine depth position data. Although the authors have discovered a promising and reproducible means to determine the ...

Thermoelectric properties of Ba8Ga16Ge30 with TiO2 nanoinclusions

This article studied the effect of the addition of TiO2 nanoinclusions on bulk Ba8Ga16Ge30clathrate. Both thermal conductivity and electrical resistivity were investigated. Results produced by the TPS system revealed that thermal conductivity decreased as the amount of nanoinclusions increased. The authors concluded that a shift in the peak value of the Seebeck coefficient had occurred. Electrical resistivity increased with the addition....
