Scholarcy highlights

  • Citations are the number of other articles citing this article, calculated by Crossref and updated daily
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • The thermal conductivity of the nanocomposites decreased upon the addition of graphene, whereas the electrical conductivity and power factor both increased significantly
  • These factors, together with a moderate Seebeck coefficient, meant that a high power factor of ∼2500 μWm–1 K–2 was reached at room temperature at a loading of 0.6 wt % graphene
  • The applications of strontium titanium oxide based thermoelectric materials are currently limited by their high operating temperatures of >700 °C
