Most dyes used in various industries are toxic and carcinogenic, thus posing a serious hazard to humans as well the marine ecosystem. Therefore, impact of released into environment has been studied extensively last few years. Heterogeneous photocatalysis proved be an efficient tool for degrading both atmospheric aquatic organic contaminants. It uses sunlight presence semiconductor photocatalyst...

The room-temperature reactions of nitric oxide with 46 atomic cations have been surveyed systematically across and down the periodic table using an inductively-coupled plasma/selected-ion flow tube (ICP/SIFT) tandem mass spectrometer. Rate coefficients and product distributions were measured for the reactions of first-row cations from K+ to Se+, of second-row cations from Rb+ to Te+ (excluding ...

Generalized trends in the formation energies of several families of perovskite oxides (ABO3) and plausible explanations to their existence are provided in this study through a combination of DFT calculations, solid-state physics analyses and simple physical/chemical descriptors. The studied elements at the A site of perovskites comprise rare-earth, alkaline-earth and alkaline metals, whereas 3d...

volves determining the population and distribution of these defects. Scanning probe microscopy was used to examine the cleaved surfaces of four binary molybdates: a-MoO3(010), Mo18O52(100), Scanning probe microscopy (SPM), a term we use here to Mo8O23(010), and h-Mo4O11(100). The Mo18O52(100) and refer collectively to scanning tunneling microscopy (STM) Mo8O23(010) surfaces were imaged in air a...
