The Bi2O4/Bi2WO6 composites were synthesized by one step hydrothermal method, which characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), Fourier transformed infrared spectroscopy (FT-IR), photoluminescence spectra (PL), photoelectron (XPS) and UV – Vis diffuse reflectance (DRS). photocatalytic performance of the composite was tested degrading methyl ora...

After the previous discovery of MgC 3 N and 4 H in IRC +10216, a deeper Q -band (31.0–50.3 GHz) integration on this source had revealed two additional series harmonically related doublets that we assigned basis quantum mechanical calculations to larger radicals 5 6 H. The results presented here extend confirm magnesium-bearing molecules +10216. We derived column densities (4.7 ± 1.3) × 10 12 fo...

ABSTRACT: Narrow-gap semiconductors are sought-after materials due to their potential for long-wavelength detectors, thermoelectrics, and more recently non-trivial topology. Here we report the synthesis characterization of a new family narrow-gap semiconductors, $R$$_{3}$Cd$_{2}$As$_{6}$ ($R=$ La, Ce). Single crystal x-ray diffraction at room temperature reveals that As square nets distort Cd v...

This cover picture shows the facile and efficient synthesis of common electrophilic haloboranes via a protonolysis reaction between Piers’ borane, HB(C6F5)2, corresponding hydrogen halides, H–X (X = Cl, Br), generating H2 gas as sole byproduct. The vacuum distillation setup shown here illustrates in situ-generated halide crossing glass bridge to react with hydridic B–H bond borane. Preparing tr...

The lattice dynamics of Ba 2 ZnTeO 6 double perovskite in three phases has been studied. Vibrational spectra and dynamic charges are calculated. In the rhomobohedral phase R3m, soft modes were found; after their condensation, C2/m was obtained, which agrees with experiment. An assessment made dependence enthalpy different on pressure; it showed that monoclinic is more favorable at 0 pressure, b...
