[ 1 ] - Optical and Dielectric studies in zirconium(IV) tungstate nanoparticles prepared by chemical coprecipitation method
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...
[ 2 ] - Green synthesis, characterization, and photo catalytic degradation efficiency of Trimanganese Tetroxide nanoparticle
Mn3O4 nanoparticles has been synthesised from Manganese (II) acetate and Simarouba Glauca leaf extract using microwave heating. This novel method of synthesis of Mn3O4 is fast, low-cost, non-toxic and environment friendly. The synthesised product was characterised by powder X-ray diffraction(XRD),Fourier transform infrared spectroscopy( FT-IR), Ultraviolet-Visible spectroscopy( UV-Visible), X-r...
