International Journal of Nanoscience, Ahead of Print. Photovoltaic is one of the best low-cost alternative energy sources. In this paper, organic semiconductors were explored as light harvesters due to their extraordinary properties, but initially, the scientific community focused on synthesizing the large bandgap organic semiconductors, which were unsuitable for photovoltaic applications. Wide bandgap organic semiconductors can capture light only from the UV–Vis region of the solar spectrum, thus showing solar cells’ power conversion efficiency (PCE) of less than 5%. By reducing the bandgap ..read more

International Journal of Nanoscience, Ahead of Print. Co/Ni/Zn triple doped [math]-Fe2O3 nanoparticles (NPs) have been synthesized via polyvinylpyrrolidone (PVP)/Azadirachta indica (A. Indica) leaf extract coating. XRD, UV–Vis, SEM, TEM, EDS, Raman spectroscopy, FTIR, VSM were used to characterize the synthesized NPs. XRD pattern revealed that the crystallite size of NPs ranges from 14[math]nm to 21[math]nm. Spherical NPs were found by SEM/TEM examination ranging from 16[math]nm to 26[math]nm of doped [math]-Fe2O3 NPs. Analysis of the magnetic properties of [math]-Fe2O3 NPs revealed antiferrom ..read more

International Journal of Nanoscience, Ahead of Print. Zinc oxide nanoparticles in the form of particles and rods were synthesized using the hydrothermal method. The scanning electron microscopy (SEM) examination was performed. The results of the SEM tests showed the nanoscale size of zinc oxide nanoparticles was (75 nm) for particles and (150 nm) for rods. An X-ray diffraction examination was carried out, and a comparison was made between the diffraction pattern of the ZnO nanoparticle and the rods. The results showed that the ZnO nanoparticle is in the hexagonal wurtzite phase of the structur ..read more

International Journal of Nanoscience, Ahead of Print. In this study, the electronic and magnetic properties of hydrogen-passivated armchair and zigzag GaN nanoribbons are investigated using density-functional theory. We explore that doped TM atom leads to additional levels in the band gap and thus plays an essential role in spin polarization and changes their properties. Depending on its location in the nanoribbon, the character of spin-dependent electronic property of a doped GaN-NR was analyzed. Our calculations show that, regardless of the position of Mn atoms, GaNNTs are stable in ferromag ..read more

International Journal of Nanoscience, Ahead of Print. This paper describes the synthesis of ZnO nanoparticles using air microplasma jets as the main reaction medium. Various techniques, including X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV—Vis spectroscopy, were employed to confirm the characterization of the artificially synthesized ZnO nanoparticles. The absence of additional peaks associated with secondary phases of ZnO, as revealed by the XRD analysis, indicates the exceptional purity of these nanoparticles. Through the use of SEM, we examined the s ..read more

International Journal of Nanoscience, Ahead of Print. Introduction: The potential of zinc oxide (ZnO) and iron oxide (Fe2O[math] nanoparticles (NPs) to induce toxic effects, especially genotoxicity, has been demonstrated in previous studies and is in part related to the ability of NPs to produce ROS. The use of antioxidants is an effective method to reduce NP-induced genotoxicity. The aim of this study was to determine the protective role of vitamin C as a potent antioxidant in ZnO-and Fe2O3 NP-induced genotoxicity in the HGF-1 cell line. Methods: Different concentrations of ZnO and Fe2O3 ..read more
