Nanostructures of zinc oxide (ZnO) are considered promising photocatalysts for the degradation organic pollutants in water. This work discusses an situ growth and UV photocatalytic effect ZnO nanostructures on a Zn plate immersed methylene blue (MB) at room temperature. First, surfaces were pretreated via sandblasting to introduce micro-scale roughness. Then, plates MB exposed light, observe na...

Despite great technological interest in nanostructured zinc oxide (ZnO) for a large variety of applications, such as lightemitting diodes, gas sensors, or dye-sensitized solar cells, their investigation as lithium-ion anode materials has been reported rather scarcely to date. In fact, although a theoretical specific capacity of about 988 mAhg@1 (if the reaction ZnO+ 3Li+3e$LiZn+Li2O is consider...

The process of effective solar energy harvesting and conversion requires efficient photon absorption, followed by charge generation separation, then electron transfer. Nanostructured materials have been considered as potential building blocks for the development future generations cells. Much attention has given to wide-bandgap semiconductor nanowires, combined sensitized with low-bandgap semic...

Pure ZnO, Ag doped ZnO and Ag-Fe co-doped ZnOwere preparedusing thermal evaporation. XRD analysis confirms that all layers present a hexagonal wurtzite structure; however, there is small shift in the peaks position due to thedistortion of film’s lattice. Scanning Electron Microscopy (SEM) reveals morphological variation surfaces doping. Ag:ZnO films have nanostructured surface, Ag-Fe:ZnO showed...

Nanostructured thin films on a silicon substrate were obtained ceramic of zinc oxide doped with manganese by high-frequency periodic pulsed laser action f ~ 10–15 kHz, wavelength λ = 1.064 μm at power density q 150 MW/cm2 in vacuum chamber p 2.7 Pa. The surface morphology and the elemental composition studied using atomic force microscopy, scanning electron X-ray spectral microanalysis. Feature...

Nanostructured materials (NSMs) have increasingly been used as a substitute for antibiotics and additives in various products to impart microbicidal effect. In particular, use of silver nanoparticles (AgNPs) has garnered huge researchers' attention as potent bactericidal agent due to the inherent antimicrobial property of the silver metal. Moreover, other nanomaterials (carbon nanotubes, fuller...

Trace elements such as zinc and iron are essential for the proper function of biochemical processes, and their uptake and bioavailability are dependent on their chemical form. Supplementation of trace metals through nanostructured materials is a new field, but its application raises concerns regarding their toxicity. Here, we compared the intracellular zinc uptake of different sources of zinc: ...
