Thermoelectric properties of Thallium Lanthanoid Tellurides, Tl10-xLnxTe6, 0.25 x 1.32, Ln = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho and Er
(University of Waterloo, 2012-06-21)Thermoelectrics can convert heat energy into electrical energy (Seebeck effect) and vice-versa (Peltier effect) without any sort of pollution. That is because there are no moving parts that can cause noise pollution and ... -
Thermoelectric properties of transition metal oxides and thallium main group chalcogenides
(University of Waterloo, 2008-08-11)Thermoelectric energy (TE) conversion can be used to create electricity from temperature gradients. Hence power can be generated from waste heat using TE materials, e.g. from the exhaust in automotives. This power in turn ... -
Thermoresponsive Starch Nanoparticles
(University of Waterloo, 2015-04-27)Thermosensitive or thermoresponsive polymers (TRPs) that undergoes an abrupt change in aqueous solubility with temperature have numerous potential commercial applications. The vast majority of TRPs reported to date are ... -
Thermoresponsive Starch Nanoparticles for Use in the Extraction of Oil from Oil Sands
(University of Waterloo, 2018-05-18)Oil sands represent the most abundant reserves of oil in the world. Nearly 97% of the oil reserves of Canada are found in the form of oil sands. Despite continued research, the extraction of oil from oil sands is costly ... -
