Pristine and modified exfoliated graphite nanoplatelets (xGnPs and M-xGnPs, respectively) were dispersed into a paraffin wax phase change material (PCM) in an effort to raise the thermal conductivity of the PCM. The addition of pure xGnPs would decrease the electrical resistivity of the composite PCM, ...
Bi2-xSbxTe3 thermoelectric materials, where x = 1.52 and 1.55 were prepared and evaluated for their thermoelectric properties. Three samples in total were prepared, two with x = 1.52 and 1.55 were synthesized at 140oC and one with x = 1.55 was synthesized at 160 oC. It was determined that the two samples synthesized ...
Single phase, orthohombic structured Ca0.98Bi0.02Mn1−xSixO3−delta (x = 0.00, 0.02 and 0.03) samples were prepared using solid state reaction. The authors investigated whether they could improve the thermoelectric properties of the product by substituting calcium and manganese with bismuth and silicon, respectively. The resulting products had ...
The authors present a method of producing Cu2CdSnSe4 quaternary nanocrystals using a colloidal synthesis route that could be used for future industrial synthesis. The nanocrystals prepared showed great potential for use as a thermoelectric material due to their high thermoelectric figure of merit (up ...
This article studies the effect of dispersion of Cu2O nanoparticles on the thermoelectric properties of Ba0.4Co4Sb12 and Sn0.4Ba0.4Co4Sb12 skutterudites. It was found that the dispersion of these nanoparticles resulted in an increased thermoelectric efficiency due to decreased electrical resistivity ...
