nanocrystalline zinc oxide (zno) powders with different morphology have been successfully synthesized by using different surfactants such as cetyl trimethyl ammonium bromide (ctab), sodium dodecyl sulphate (sds), and tri ethanol amine (tea) via hydrothermal method. the products were characterized by means of powder x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electr...
Large-scale synthesis and release of nanomaterials in environment is a growing concern for human health and ecosystem. Therefore, we have investigated the cytotoxic and genotoxic potential of zinc oxide nanoparticles (ZnO-NPs), zinc oxide bulk (ZnO-Bulk), and zinc ions (Zn2+) in treated roots of Allium cepa, under hydroponic conditions. ZnO-NPs were characterized by UV-visible, XRD, FT-IR spect...
In the present work, ZnO/CuO composite nanostructures have been grown on uorine doped tin oxide coated glass substrate by aqueous chemical growth method. To observe the e ect of post growth annealing (500 ◦C, 1 min) on the structural properties of ZnO nanorods scanning electron microscope and X-ray di raction techniques have been utilized. SEM images of post growth annealed (post growth anneale...
In this research work, the production of undoped and silver (Ag) doped zinc oxide (ZnO) thin films for food packaging applications was developed. The main goal was to determine the influence of coatings morphology and thickness on the antimicrobial performance of the produced samples. The ZnO based thin films were deposited on PET (Polyethylene terephthalate) by means of DC reactive magnetron s...
We report the influence of zinc oxide (ZnO) seed layers on the performance of ZnO-based memristive devices fabricated using an electrodeposition approach. The memristive element is based on a sandwich structure using Ag and Pt electrodes. The ZnO seed layer is employed to tune the morphology of the electrodeposited ZnO films in order to increase the grain boundary density as well as construct h...
Zinc oxide nanocomposite was prepared by sol gel method. Synthesized nanoparticle was characterized by X-ray diffraction and FT-IR spectroscopy. According to XRD analysis the crystallite size was found to be 30nm (approx) for ZnO. The formation of ZnO is confirmed by FT-IR. ZnO is used for the preparation of HRP/ ZnO/PVA/Au electrode. ZnO nanocomposite is mixed with PVA Solution and a thin laye...
Metal-doped zinc oxide (ZnO) nanorod arrays have attracted much attention due to improvement in their electrical, structural, and optical properties upon doping. In this chapter, we discuss the effects of aluminum (Al)and iron (Fe)-doping on ZnO nanorod arrays properties particularly for humidity sensor applications. Compared to Fe, Al shows more promising characteristics as doping element for ...
This review focuses on the most recent applications of zinc oxide (ZnO) nanostructures for tissue engineering. ZnO is one of the most investigated metal oxides, thanks to its multifunctional properties coupled with the ease of preparing various morphologies, such as nanowires, nanorods, and nanoparticles. Most ZnO applications are based on its semiconducting, catalytic and piezoelectric propert...
With increasing production and applications of nanostructured zinc oxide, e.g., for biomedical and consumer products, the question of safety is getting more and more important. Different morphologies of zinc oxide structures have been synthesized and accordingly investigated. In this study, we have particularly focused on nano-micro ZnO tetrapods (ZnO-T), because their large scale fabrication h...
