Anisotropic thermoelectric properties in layered complex nitrides with α-NaFeO2-type structure
Electronic structures and thermoelectric transport properties of α-NaFeO2-type d0-electron layered complex nitrides AMN2 (A = Sr or Na; M = Zr, Hf, Nb, Ta) were evaluated using density-functional theory and Boltzmann theory calculations.

Solid-solution strengthening of Ti-Zr-Hf-Nb-Ta-Fe refractory high-entropy alloy
Ti-Zr-Hf-Nb-Ta system refractory high-entropy alloys (RHEAs) exhibits outstanding tensile ductility in room temperature. However, the moderate yield strength of them is insufficient.

The Tarim Basin, China, a prospect for plume-related Zr(Hf)-Nb(Ta)-REY-Ga-U mineralization
This study is based on published data from the Tarim and Emeishan Large Igneous Provinces (TLIP and ELIP, respectively). The data are interpreted in a comparative manner, using the well-studied ELIP’s mineralization as a reference.

Pt-induced atomic-level tailoring towards paracrystalline high-entropy alloy
Paracrystalline state is still challenging to reach in alloy systems in a controlled manner. Here, the authors present an atomic-level tailoring route to create paracrystalline Zr-Nb-Hf-Ta-Mo high-entropy alloy through local amorphization induced by ...
