Electron, phonon and thermoelectric properties of CuPS crystal calculated at DFT level.

The promising class of the environment-friendly thermoelectrics is the copper-based argyrodite-type ion-conducting crystals exhibiting just extraordinary low thermal conductivity below the glass limit associated with the molten copper sublattice leading to a softening of phonon modes. To explain why the argyrodite structure containing copper ions favors the low thermal conductivity, we have utilized the ab initio calculations of the electron, phonon, and thermoelectric properties of CuPS crystal in the framework of the density functional and Boltzmann transport theories. To obtain the reliable thermoelectric properties of CuPS, we take into account the dependence of the electron effective mass m on the redundant carrier concentration n.

Entropy-Induced Multivalley Band Structures Improve Thermoelectric Performance in -CuP(SSe) Argyrodites.

Searching for novel low-cost and eco-friendly materials for energy conversion is a good way to provide widespread utilization of thermoelectric technologies. Herein, we report the thermal behavior, phase equilibria data, and thermoelectric properties for the promising argyrodite-based CuP(SSe) thermoelectrics. Alloying of CuPSe with CuPS provides a continuous solid solution over the whole compositional range, as shown in the proposed phase diagram for the CuPS-CuPSe system.

Paxillin-dependent regulation of IGF2 and H19 gene cluster expression.

Paxillin (PXN) is a focal adhesion protein that has been implicated in signal transduction from the extracellular matrix. Recently, it has been shown to shuttle between the cytoplasm and the nucleus. When inside the nucleus, paxillin promotes cell proliferation.
