Bicone nanoflower evolution and multi-peak emission of polymer caped Cu doped ZnO Hind Neelamkodan, Unikoth Megha, Madhu Chennabasappa, Manathanath Puzhakkara Binitha Nanotechnology, 2024 A low-temperature polymer-assisted wet chemical method was used to synthesise Cu-doped ZnO bicone nanoflowers at three different polyethylene glycol (PEG) concentrations. The effects of PEG concentration on the structural, morphological and optical properties of Cu doped ZnO nanostructures were studied. X-ray diffraction studies revealed that the as-synthesized Cu doped ZnO nanostructures are highly crystalline with a hexagonal wurtzite phase. The scanning electron microscopy analysis showed that the prepared nanostructures have bicone- nanoflower morphology and PEG concentration has strongly influenced the size as well the shape of nanoflowers. The TEM analysis confirmed the nanoflower morphology and the presence of diffraction planes obtained from the XRD data. The compositional analysis was performed by x-ray photoelectron Spectroscopy. The surface passivation effect of PEG on the band gap energies was studied by analysing UV -visible spectra of all the samples. The room-temperature fluorescent spectra of all the nanoflowers showed multiple peak emissions, both in the ultra-violet and visible regions, with varying intensities. These recasted multiple peaks are attributed to the morphological modification caused by the PEG addition.
Green Synthesis of Cerium Oxide Nanoparticles, Antibacterial Studies and as Catalyst for the Conversion of Cotton Seed Oil into Biodiesel G.E. Rudreshappa, Madhu Chennabasappa, S. Sreenivasa, S. Vijaya Kumar, K.V. Yatish, et al. Asian Journal of Chemistry, 2022 Cerium oxide nanoparticles were synthesized by employing solution combustion method using environmental friendly, polypeptide and acids rich, Butea monosperma seed powder as fuel. Phase purity, crystallite size were determined from X-ray diffraction (XRD). The trace amount of organic species attached to the surface of the nanoparticles was identified using Fourier transform infrared spectroscopy (FTIR). Morphological studies are performed on SEM and the particle shape-size distributions are studied using TEM. Electron diffraction on the nanoparticles revealed good crystallinity of the synthesized samples. Band gap increased with decreasing particle size as confirmed from the diffuse reflectance spectroscopy (DRS). White light luminescence capabilities of CeO2 nanoparticles were studied using photoluminescence spectroscopy. In vitro antibacterial activity studies to determine the zone of inhibition (ZOI) and catalytic property for the conversion of cotton seed oil into biodiesel were performed.
