We report on the superconductivity in ternary transition metal tellurides Ta2Pd3Te5 and Nb2Pd3Te5, which have a one-dimensional crystal structure. Single-crystalline polycrystalline samples of show nonmetallic electron conduction, while Ti or W doping results metallic behavior with bulk superconducting at 2–4 K. In contrast, are found to be isostructural Ta2Pd3Te5, 3.3 The structure physical pr...

Abstract. Absorption cross sections of emerging greenhouse gases (GHGs) were measured to estimate the radiative efficiency using high-resolution Fourier transform infrared spectroscopy (HR-FTIR). For quantitative spectroscopy, Beer–Lambert parameters absorber pressure, temperature, and optical path length (OPL) accurately determined be traceable primary standards. The OPL multipass cell mounted...

Borosulfates are an expanding class of silicate-analogous materials. We report the syntheses and crystal structures two unconventional cadmium borosulfates. Cd[B2O(SO4)3] crystallises in a new structure type space group Pnma (no. 62, a=896.92(8), b=1152.0(1), c=872.75(8) pm, 1380 refl., 94 ref. param., wR2=0.112). Cd4[B2O(SO4)6] adapts α-Mg4[B2O(SO4)6]-type with P 147, a=822.22(4), c=797.88(5) ...

Layered perovskite-like oxide Bi 3 Ti 1.5 W 0.5 O 9 has been synthesized by the method of high-temperature solid-state reaction. The X-ray diffraction study showed that compound is single-phase and structure family Aurivillius phases (AP) with parameters close to orthorhombic unit cell corresponding space group A2 1 am. temperature dependences relative permittivity ε/ε 0 loss tangent tgsigma ar...

Oxide materials with a perovskite-derived layered structure often show better photocatalytic performance compared to nonlayered of similar composition. Here we investigate the catalytic activity for oxygen evolution reaction (OER) on surfaces Carpy–Galy oxides Sr2Ta2O7 and Sr2Nb2O7. We find that (010) surface parallel layering shear plane is not relevant photocatalysis. The (100) perpendicular ...
