A procedure was developed that allows precise determination of molybdenum isotope abundances in natural samples. Purification of molybdenum was first achieved by solvent extraction using di(2-ethylhexyl) phosphate. Further separation of molybdenum from isobar nuclides was obtained by ion chromatography using AG1-X8 strongly basic anion exchanger. Finally, molybdenum isotopic composition was mea...

In Methanobacterium wolfei two formylmethanofuran dehydrogenases are present, one of which is a molybdenum- and the other a tungsten enzyme. We report here that also the 'molybdenum' enzyme contained tungsten when the archaeon was grown on molybdenum-deprived medium supplemented with tungstate (1 microM). Unexpectedly the tungsten-substituted molybdenum enzyme was catalytically active and displ...

Inverted organic photovoltaic solar cells were fabricated with the configuration of FTO/TiO2/P3HT:PC61BM/MoO3/Ag. Besides, influence transport layers, titanium dioxide and molybdenum trioxide, on performance investigated. These compounds showed excellent optical (around 80% for trioxide 95% dioxide), electrical (like charge carrier density 3.3 x1015 cm-3 2.5 x1014 molybdenum, respectively) stru...

(PyH)2[MoOCl5] was obtained in the form of emerald green crystals unintentionally from (PyH)5[MoOCl4(H2O)]3Cl2 acetonitrile. has been used as a starting material molybdenum(V) coordination chemistry for decades, yet its true identity not known until now. The X-ray structure analysis undoubtedly confirmed existence this compound. [MoOCl5]2− ion displays usual structural characteristics mononucle...
