There is a growing concern for finding alternative solutions to construction materials in order to minimize their environmental impact as well as enhancing their service life. This study investigated the durability of cementitious mortars prepared by replacing fine aggregate (sand) with recycled tyre shreds and crumbs, aiming at providing an alternative outlet to tyre waste disposal. Tyre shreds obtained at different particle ...
Thermal management is extremely important for large size batteries, however, inaccurate values have been used in the past for modeling. This paper investigates the thermal conductivity of the composite cathodes. This knowledge is needed to find the true thermal properties of lithium polymer batteries. The guarded heat flow meter was used to find these values, achieving a 5% precision ...
Thermoelectric (TE) generators have very important applications, such as emerging automotive waste heat recovery and cooling applications. This study investigates how thermal conductivity, seebeck coefficient, and resistivity of bismuth telluride changes with increasing isothermal aging. The thermal conductivity was tested with the Transient Plane Source (TPS) method. Both bismuth telluride n and p type were tested for 2 wk, 8 wk, 6 mo, 1 yr, and 2 yr of isothermal aging at 240 degrees Celsius. The ...
