Copper oxide nanopellets (CONPs) were produced by hydrothermal strategy. The particles were characterized by distinctive techniques. The synthesized particles were found to have pellet morphology with nonuniform thickness and varying sizes extending between 200 and 550 nm. Studies revealed their microbial nature against both Gram-positive and Gram-negative microscopic organisms, specifically Staphylococcus aureus, Bacillus subtilis, Pseudomonas fluorescens, and Escherichia coli and a plant parasitic pathogen Fusarium oxysporum. Studies demonstrated the antioxidant ability of CONPs at higher concentrations. In this paper, cytotoxicity was measured by blood hemolysis. Anticancer activity of CONPs tested against PC-3, HCT116, A549 and MDA-MB-231 cell lines after 24 hours exhibited IC50 values of 72.27, 144.2, 173.9, and 13.07 μg/mL, respectively. Although these phenomena have been determined in other reports, this report is indeed of significance for CONPs within the particle length of 200–550 nm.
The thiourea doped lithium sulfate single crystal was grown by solution growth slow evaporation technique. The unit cell parameters of the grown crystal determined by X-ray diffraction studies indicated that the crystal belongs to a monoclinic crystal system with noncentrosymmetric space group P2. UV-visible spectral study signified that the crystal possesses an energy gap of 4.54 eV with 68% transparency in the visible region. The grown crystals were irradiated by Co-60 gamma radiations with different doses of 10 kGy, 30 kGy & 50 kGy and studied irradiation effect on powder XRD, dielectric properties, mechanical hardness, linear transmittance and second harmonic generation of the crystal. It is observed that the crystallite size, energy gap and transparency are decreased; whereas, the dielectric constant, AC conductivity, microhardness and SHG efficiency are increased upon an increase in radiation dose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
