Zinc oxide nanosheet is assessed as a selective adsorbent for the detection and adsorption of cadmium using simple eco-friendly extraction method. Pure zinc oxide nanosheet powders were characterized using field emission scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The zinc oxide n...

in this study, zinc oxide nanoparticles (znonps) were synthesized by chemical method and their antibacterial efficiency against a clinical isolate of staphylococcus aureus was studied. the zinc oxide nanoparticles have shown a commendable inhibition effect on the growth of most notorious bacterial pathogen s.aureus. the nanoparticles size and shapes were characterized by transmission electron m...

We investigated the effect of locally applied zinc on the healing of partial-thickness skin wounds in the domestic pig using two zinc compounds (zinc oxide and zinc sulfate) in two different vehicles (a gauze compress and a collagen sponge). The rate of re-epithelialization was determined morphometrically 48 and 64 hr after infliction of standardized square wounds (4.8 cm2 and 400-microns deep)...

In this research, the inhibitory effects of silver nanoparticles and zinc oxide nanoparticles,  in vitro, on disease stone fruits bacterial canker caused by Pseudomonas syrigae pv. Syringae and disease bacterial blight caused by Xanthomonas arboricola pv. juglandis, were studied. Different concentrations of nanoparticles were prepared on Mueller Hinton agar medium in two different ways in a com...

This study is focused on the evaluation of zinc oxide properties and behavior at commercially available cosmetic ingredients by in vitro methods of dermal absorption of zinc oxide and its subsequent chemical determinations. Two methods for determination of ZnO were used and the results were compared. The spectrophotometric method (SPM) was selected for its sensitivity and atomic absorption spec...

Zinc oxide nanorod arrays (ZnO NRs) were grown on the ZnO seed layers via an aqueous solution using hydrothermal method and their photovoltaic properties were investigated. It was found that the growth period of 20 minutes is the optimum condition for ZnO nanorods growth, the cell containing these nanorods was considered as a reference cell. In order to further increase the cell performance, Zn...

Light, inexpensive, effective: Nanostructured Co(3)O(4) clusters (see picture) in mesoporous silica are the first example of a nanometer-sized multielectron catalyst made of a first-row transition-metal oxide that evolves oxygen from water efficiently. The nanorod bundle structure of the catalyst results in a very large surface area, an important factor contributing to the high turnover frequency.
