We report on the electrochemical fluorination of A-site vacant perovskite ReO3 using high-temperature solid-state cells as well room-temperature liquid electrolytes. Using galvanostatic oxidation and impedance spectroscopy, we find that can be oxidized by approximately 0.5 equiv electrons when in contact with fluoride-rich Results from our density functional theory calculations clearly rule out...

Detailed understanding of the elastic properties and mechanical durability ceramic materials is crucial for their utilization in advanced microelectronic or micro-electromechanic devices. We have systematically investigated 97 binary d-metal oxides using hybrid density functional methods. report polycrystalline single-crystal bulk moduli symmetrized constants studied compare with experimental i...

We report high-resolution angular magnetoresistance (AMR) experiments performed on crystals of ReO$_3$ with high mobility (90,000 cm$^2$/Vs at 2 K) and extremely low residual resistivity (5-8 n$\Omega$cm). The Fermi surface, comprised intersecting cylinders, supports open orbits. $\rho_{xx}$ in a magnetic field $B$ = 9 T displays singular pattern behavior. With $\bf E\parallel \hat{x}$ B$ initi...

A new hydrated sodium nickel fluoride with nominal composition NaNiF3·3H2O was synthesized using an aqueous solution route. Its structure was solved by means of ab initio methods from powder X-ray diffraction and neutron diffraction data. NaNiF3·3H2O crystallizes in the cubic crystal system, space group Pn3̅ with a = 7.91968(4) Å. The framework, derived from the ReO3 structure type, is built fro...

Due to its high thermal conductivity and favorable machinability, molybdenum–rhenium (Mo–Re) alloys have huge prospects in the field of high-temperature heat pipes. However, weldability Mo–Re has not yet been systematically investigated. Based on an orthogonal test, influence law single-mode fiber laser welding parameters weld profile mechanical properties joints was studied. Furthermore, exist...
