Utilizing the thermoelectric effect to its maximum potential requires a minimization of the thermal conductivity due to phonons without reducing the electrical conductivity. Creating a material with highly localized phonon modes is one way of accomplishing this. Randomly distributing heavy hafnium oxide ...
Using these experimental values, the thermal diffusivity and thermal conductivity of each material were determined at room temperature with a hot disk sensor, which is a transient technique for rapid thermal conductivity measurement. Finally, the linear coefficients of thermal expansion of these materials...
Numerous studies have demonstrated significant interest in increasing the material and thermal conductivity of nanofluids using either theoretical or experimental methods in recent times, which has sparked a lot of activity in the area of nanofluids (Mahian et al., 2014, 2013). Studies available in ...
