Grain size and compositional gradient dependence of thermoelectric performance for Cu3−Ni SbSe4 materials

Finite Element Modeling of Strain Rate and Grain Size Dependency in Nanocrystalline Materials

Nanocrystalline materials show a higher strain-rate sensitivity in contrast to the conventional coarse-grained materials and a different grain size dependency. To explain these phenomenon, a finite element model is constructed that considers both grain interior and grain boundary deformation of nanocrystalline materials. The model consist of several crystalline cores with different orientations...

Eco-friendly high-performance silicide thermoelectric materials

Silicide-based thermoelectrics are examples of cost-efficient and environmentally friendly new energy materials, which can be used for power-generation applications in the range of 500–800 K. We review the research focusing on the exploration of n-typeMg2IV-based solid solutions (IV= Si, Ge and Sn) and summarize the most prominent discoveries achieved so far in their studies. Owing to their sup...

Effects of barley grain particle size on dairy cow performance

The Effect of Aperture Size on the Cavity Performance of Solar Thermoelectric Generator

   In this manuscript, a solar cavity packed with thermoelectric generator modules is investigated numerically. The hot plate of TEG modules make the inner surface of the cube, and the cold plate is outside of the cavity, under natural convection. The TEG modules are electrically in series. The solution algorithm using the equations of heat transfer and generated power of TEG modules is d...

Data-Driven Review of Thermoelectric Materials: Performance and Resource Considerations

In this review, we describe the creation of a large database of thermoelectric materials prepared by abstracting information from over 100 publications. The database has over 18 000 data points from multiple classes of compounds, whose relevant properties have been measured at several temperatures. Appropriate visualization of the data immediately allows certain insights to be gained with regar...
