New energy from rare earth
A team of scientists has discovered a novel approach to crafting higher thermoelectric efficiencies, which can help develop electrical energy from waste heat such as that emitted by internal combustion engines. Professor André Strydom from the Department of Physics at the University of Johannesburg (UJ) collaborated with researchers from the Chinese Academy of Sciences in Beijing; Institute of Solid State Physics in Vienna; the Max Planck Institute in Dresden; and the University of Aarhus in Denmark in the discovery. A research article, Large Seebeck Effect by Charge-Mobility Engineering, co-authored by Prof Strydom, appeared in the June 2015 edition of Nature Communications.
