Influence of Gd Doping in Structural, Morphological and Optical Properties of Zno Nanostructures Synthesised Via Sol-Gel Processes
Abstract: In this study, nanocrystalline Zn1-xGdx (x=0.0 and 0.03) samples were synthesised via the Sol-gel combustion process. An array of analytical techniques was employed to examine the prepared samples to determine their different physical features. For both pristine and Gd-doped samples, the crystal symmetry is hexagonal with the P63mc space group which is verified via the Rietveld refinement analysis of X-ray diffraction (XRD) data. The atoms' bond length Zn-O and bond …

Modification of Acrylonitrile-Methylacrylate Copolymer by Gamma Irradiation
Abstract: AbstractRadiative degradation of acrylonitrile-methylacrylate (AM) copolymer has been investigated by electron spin resonance (ESR) and infrared (IR) spectroscopy. The ESR spectrum observed for AM copolymer irradiated to a dose of 12 Mrad is a triplet with an intensity ratio of 1:3:1. The ESR spectrum is simulated by total-curve-fitting method and component spectra are generated. Magnetic parameters of component spectra are evaluated. Component triplet spectrum with magnetic parameters ni=3, mi=1 is …
