Tuning thermoelectric materials for efficient power generation https://www.mpg.de/19984293/thermoelectric-materials-waste-heat-electricity
Adding titanium to NbFeSb makes the thermoelectric material more efficient in generating electricity from waste heat, as researchers of the Max-Planck-Institut für Eisenforschung demonstrate. Optimized thermoelctrics could help to use fossil fuels and biofuels more efficiently.
