A solid solution was found to exist in the quaternary Li(2)O-MgO-V(2)O(5)-MoO(3) system between the two phases Mg(2.5)VMoO(8) and Li(2)Mg(2)(MoO(4))(3). Both Mg(2.5)VMoO(8) and Li(2)Mg(2)(MoO(4))(3) are isostructural with the mineral lyonsite, and substitution according to the formula square(1/4-x/6)Li(4x/3)Mg(15/4-7x/6)V(3/2-x)Mo(3/2+x)O(12) (0 < or = x < or = 1.5, where square denotes a catio...

The title complex, [Mo(C(15)H(22)BN(6))(C(7)H(7)O)(2)(NO)], contains an {MoNO}(4) core stabilized by κ(3)--hydrotris-(3,5-dimethyl-pyrazol-1-yl)borate, [Tp(Me2)](-), and two anionic m-cresolate ligands, leading to a distorted octa-hedral geometry for the Mo atom. The short Mo-O bond lengths [1.935 (2) and 1.971 (2) Å], as well as large Mo-O-Csp(2) angles [134.2 (2) and 143.54 (19)°], indicate d...

The catalytic wet oxidation process was used to study the degradation of carbohydrates in wastewater with glucose as a model compound. transition metals Co and Mo were transformed into their insoluble metal oxide forms, Co3O4 MoO3. A novel catalyst prepared by using CuNiIn alloy, which oxidized at 700 °C generate an mixed oxide. Wet reactions performed 150–210 for 60 min 20 bar O2 pressure. per...

the molybdenum dicilicide is an intermetallic compound with two allotropies tetragonal ?-mosi2 and hexagonal ?-mosi2.the ?-mosi2 phase is established to 1900 ?c and ?-mosi2 phase from 1900 to 2050 ?c. this material has considerable properties that provide different applications in different industries such as air-space industry and gas turbines. the molybdenum synthesis can be down in various w...

The influence of implanted Si, Mo and Ce vs. the as-received austenitic AISI 304 stainless steel has been studied after isothermal oxidation in air at 900 8C for 32 h. The oxide layer formed was characterised by means of conventional X-ray diffraction, scanning electron microscopyyenergy-dispersion spectroscopy and X-ray absorption spectroscopy (XAS) techniques. The projected ranges of the impl...

The color changes in chemo- and photochromic MoO3 used in sensors and in organic photovoltaic (OPV) cells can be traced back to intercalated hydrogen atoms stemming either from gaseous hydrogen dissociated at catalytic surfaces or from photocatalytically split water. In applications, the reversibility of the process is of utmost importance, and deterioration of the layer functionality due to si...
