Raviraj M. Kulkarni; Ramesh S. Malladi; Manjunath S. Hanagadakar

Volume 3, Issue 8 , 2018, , Pages 521-525

  Photocatalytic degradation of textile dye derivative Methyl Orange (M.O) has been studied in aqueous medium using 2% copper doped zinc oxide (2% Cu-ZnO) nanoparticles under UV irradiation. Simple inexpensive chemical precipitation method was used for synthesis of pure and copper doped zinc oxide nanoparticles. ...  Read More

Ag-TiO2 nanoparticles for photocatalytic degradation of sparfloxacin

Raviraj M. Kulkarni; Ramesh S. Malladi; Manjunath S. Hanagadakar

Volume 3, Issue 8 , 2018, , Pages 526-529

  Liquid Impregnation (LI) technique was developed to prepare 1% and 2% Ag doped Titania nanoparticles. The characterization of the prepared nanoparticles was achieved by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDX) and Transmission Electron Microscopy ...  Read More

Effect of Dy3+ substitution on microwave behaviour of nanocrystalline Mn-Zn Ferrite

P. Neelima; S. R. Murthy

Volume 3, Issue 7 , 2018, , Pages 464-468

  Microwave-hydrothermal (M-H) method had been employed to synthesize a series of Dy3+doped Mn-Zn ferrite Mn0.6Zn0.4Fe2–xDyxO4 (x=0, 0.01, 0.03, 0.05, 0.07, 0.09) nanopowders at 160°C/30 min. The prepared samples have been characterized by Fourier Transform Infrared Spectrometer. The grain size ...  Read More

Investigation of deep electronic levels in n‐type and p‐type 3C‐SiC using photoluminescence

Martin Wilhelm; Mikael Syväjärvi; Peter J. Wellmann

Volume 2, Issue 12 , 2017, , Pages 769-773

  Among the various SiC polytypes, cubic 3C‐SiC is much more difficult to grow in high crystalline quality than the commercially introduced hexagonal 6H‐SiC and 4H‐SiC counterparts. Besides some benefits of 3C‐SiC for transistor applications related to a greater electron mobility and a lower metal‐oxide‐semiconductor ...  Read More
