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 ...

Mechanical flexibility, low cost, and lightweight design are crucial elements for high demand electronic devices and has increased the application of flexible printed circuit board (FPCB). However, FPCB exhibits stress under operating conditions compared to rigid printed circuit board (RPCB), and was studied to investigate the effects of airflow rate and heat on FPCB attached with a ball grid array (BGA) package. Thermal conductivity and specific heat were measured using ...

In this paper, the thermal conductivity of rock samples was tested using three different methods: the transient plane source (TPS) method, the divided bar method, and calorimetric method. Two rock samples were tested under the TPS method with different procedures (i.e. heating and cooling times, sizes of samples). The results of the TPS method were slightly lower than the results of the divided bar method, but yielded an acceptable ...

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 ...

A numerical model is developed to describe the thermal conductivity, hydration, and moisture content of Portland cement mortar specimens. In order to develop the model, the thermal conductivity and specific heat of the mortar specimens were measured using the transient plane source method. The model was able to correctly describe the evolution of heat and the degree of hydration in both semi-adiabatic and steam curing conditions....
