چکیده

The possibility of detection methane using fiber-optical sensor with ZnO-SnO2-Fe2O3 photocatalyst was demonstrated. Photocatalytic composite element prepared by non-isothermal polymer-salt method from solutions inorganic metal salts and polyvinylpyrrolidone. Optical is carrying out Bragg diffraction grating at the temperature variations during photocatalytic oxidation.

Synthesis and Characterization of Tb[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O and Eu[N(CN)<sub>2</sub>]<sub>3</sub>·2H<sub>2</sub>O: Two New Luminescent Rare-Earth Dicyanamides

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...

In Situ Observation of Dehydration-Induced Phase Transformation from Na<sub>2</sub>Nb<sub>2</sub>O<sub>6</sub>H<sub>2</sub>O to NaNbO<sub>3</sub>

We have monitored the phase transformation from a Sandia octahedral molecular sieve Na2Nb2O6−H2O to a piezoelectric NaNbO3 nanowire through in situ X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements at high temperatures. After dehydration at 288 °C, the Na2Nb2O6−H2O becomes significantly destabilized and transforms into NaNbO3 with the increase of time. The phase tr...
