Nanoparticles of zirconium(IV) tungstate are prepared by chemical co-precipitation method. Thecharacterizations have been carried out by TG/DTA, DSC, AFM, XRD, FTIR and UV-Vis spectrum. PLspectrum shows two emission bands at 350 nm and at 477 nm. The effects of frequency on the dielectricbehavior and ac electrical conductivity have been studied. The dielectric constant is found to be 119.43 at1...

Tungstate-catalyzed hydrogenolysis of sugars in untreated woody biomass to ethylene glycol (EG) has so far been unsuccessful. This work shows that production EG is predominantly hampered by the presence inorganic impurities biomass, which can be selectively removed an acid leaching step at room temperature. Catalytic and acid-leached samples was run 245 °C using sodium polytungstate Raney Ni ca...

Synchrotron-based X-ray absorption spectroscopy (XAS) of select surface soil samples obtained from Camp Edwards, Massachusetts, small arms ranges indicate that little tungsten metal remains in the soil and that is not stable in the natural environment. X-ray absorption near edge structure (XANES) studies indicate rapid oxidation of tungsten metal to form tungsten oxides W(VI), polytungstates, t...

Ag loaded metal tungstate-organic framework-based nanocomposite (g-C3N4/Ag/ZnWO4), which generates greater number of oxygen defects plays crucial role in the selective detection toxic ions solution.
