TL;DR: In this paper, the authors focus on the significant enhancements in thermoelectric performance that have been achieved through nanostructuring, and the principal factor behind the improved performance appears to be increased phonon scattering at interfaces, which results in a substantial reduction in the lattice contribution to thermal conductivity.

TL;DR: In this paper, the authors present the science and technology that underpins thermoelectric generators (TEGs) and outline the key challenges associated with the development of new materials and devices that offer higher power output, while matching TE solutions to the wide range of applications that would benefit from energy harvesting.

TL;DR: In this article, the purity and structural stability of the high thermoelectric performance Cu12Sb4S13 and Cu10.4Ni1.6Sb 4S13 tetrahedrite phases were studied at high temperature by Rietveld refinement using high resolution X-ray powder diffraction data, DSC/TG measurements and high resolution transmission electron microscopy.

TL;DR: In this paper, the relationship between structural and magnetic properties in stoichiometric pyrrhotite has been investigated using variable-temperature neutron-diffraction data, and the magnetic transition is accompanied by a structural transformation from the monoclinic 4C structure to a hexagonal cation-deficient NiAs structure, in which the vacancies are statistically distributed between all layers.

TL;DR: The magnetic susceptibilities of La2Mg1−xZnxIrO6 (0 < x < 1), La2NiO6, BaLaFeO6 and BaLaCoO6 have been measured as a function of temperature and applied magnetic field.
