Journal ArticleDOI
Green synthesis of NiO nanoparticles using Moringa oleifera extract and their biomedical applications: Cytotoxicity effect of nanoparticles against HT-29 cancer cells.
A. Angel Ezhilarasi,J. Judith Vijaya,K. Kaviyarasu,K. Kaviyarasu,Malik Maaza,A. Ayeshamariam,L. John Kennedy +6 more
TL;DR: MTT assay measurements on cell viability and morphological studies proved that the synthesized nickel oxide nanoparticles posses cytotoxic activity against human cancer cells and the various zones of inhibition, and revealed the effective antibacterial activity of NiO nanoparticles against various Gram positive and Gram negative bacterial pathogens.
Journal ArticleDOI
Green synthesis of NiO nanoparticles using Aegle marmelos leaf extract for the evaluation of in-vitro cytotoxicity, antibacterial and photocatalytic properties.
A. Angel Ezhilarasi,J. Judith Vijaya,K. Kaviyarasu,K. Kaviyarasu,L. John Kennedy,R. Jothi Ramalingam,Hamad A. Al-Lohedan +6 more
TL;DR: The green synthesis of NiO nanoparticles using Aegle marmelos as a fuel is reported and it is found that the cell viability of A549 cells was effectively reduced and it showed better antibacterial activity towards gram positive bacterial strains.
Journal ArticleDOI
Optical and magnetic properties of Mg-doped ZnFe2O4 nanoparticles prepared by rapid microwave combustion method
Ayyar Manikandan,J. Judith Vijaya,M. Sundararajan,C. Meganathan,L. John Kennedy,Mohamed Bououdina +5 more
TL;DR: In this paper, powder X-ray diffraction (XRD), high resolution scanning electron microscopy (HR-SEM), energy dispersive Xray analysis, UV-Visible diffuse reflectance spectra (DRS), photoluminescence (PL) spectra and vibrating sample magnetometer (VSM).
Journal ArticleDOI
Adsorption of phenol from aqueous solutions using mesoporous carbon prepared by two-stage process
TL;DR: In this article, the adsorption behavior of phenol onto the porous carbon was studied by varying the parameters such as agitation time, phenol concentration, pH and temperature, and the results showed that the sorption process was found to be exothermic in nature.
Journal ArticleDOI
Synthesis, optical and magnetic properties of pure and Co-doped ZnFe2O4 nanoparticles by microwave combustion method
TL;DR: In this paper, the magnetic properties of the synthesized spinel ferrites were investigated using room temperature vibrating sample magnetometer (VSM) and their hysteresis loops were obtained.
