On the use of thermoelectric (TE) applications based on commercial modules: The case of TE generator and TE cooler
(Department of Physics, Aristotle University of Thessaloniki, GreeceDepartment of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia, CyprusCorrespondence Address: Zorbas, K.Department of Physics, Aristotle University of ThessalonikiGreece, 2010)
In recent years, thermoelectricity sees rapidly increasing usages in applications like portable refrigerators, beverage coolers, electronic component coolers etc. when used as Thermoelectric Cooler (TEC), and Thermoelectric ...
Long-time Stability of Mg2(Si-Sn-Ge) - Based Thermoelectrics Under Large Temperature Gradient Conditions
(Elsevier Ltd, 2015)
We study the thermoelectric properties and stability of Mg2(Si-Sn-Ge) composite, prepared by a combination of ball milling process and heating treatment followed by Spark Plasma Sintering and densification. The goal of ...
