WebMetal oxides are particularly promising high-temperature thermoelectric (TE) materials due to their excellent high-temperature stability, eco-friendliness and cost-effectiveness. Yet, their poor TE performance has become the main bottleneck for their wide application. ... c Department of Chemistry, University of Cambridge, Cambridge CB2 1EW, UK WebA calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature. When an endothermic reaction occurs, the heat required is absorbed ...
