The composites graphite/ZnO were prepared using calcination method. Zinc chloride (ZnCl2) and sodium carbonate (Na2CO3) were used for synthesis of zinc oxide (ZnO), whereas micromilled and natural graphite were used as the matrix for ZnO nanoparticles growing. During the reaction of ZnCl2 with saturated aqueous solution of Na2CO3 new compound Na2Zn3(CO3)4•(H2O)3 originates. During the calcinati...

In this paper, we demonstrate a novel and direct synthesis of hexagonal-shaped zinc oxide (ZnO) nanorods at very low temperature of ~ 80C simply by using metallic zinc foil and de-ionized (DI) water with few drops of ethanol. The formation of ZnO structures by the reaction of metals with DI water is suggested to occur due to the oxidation of metallic zinc in presence of water. The synthesized Z...

In this paper, capacitive-type humidity sensors were prepared by sequentially drop-coating the aqueous suspensions of zinc oxide (ZnO) nanopowders and polyvinyl pyrrolidone-reduced graphene oxide (PVP-RGO) nanocomposites onto interdigitated electrodes. Significant improvements in both sensitivity and linearity were achieved for the ZnO/PVP-RGO sensors compared with the PVP-RGO/ZnO, PVP-RGO, and...

Context: Cadmium oxide nanoparticles (CdO NPs) are employed in optoelectronic devices and as a starting material for generating quantum dots as well as for medical imaging and targeting of pharmaceutical agents to disease sites. However, there are lack of data concerning shortand long-term effects of CdO NPs on the lungs. Objective: To determine the effects of inhaled CdO NPs at an occupational...

in this paper, synthesis of the flower-like zinc oxide was performed using microwave assisted dicationic ionic liquid [mmp(im)2 ]br2 . the polycrystalline flower-like zinc oxide nanostructure was obtained when a suitable mole ratio (ionic liquid /zinc acetate) and short duration microwave was used. x-ray diffraction (xrd), scanning electron microscopy (sem), and photoluminescence (pl) spectra w...

CdxTeyOz/CdS/ZnO heterostructures were obtained by the SILAR method using ionic electrolytes. A CdS film was formed as a buffer layer for better adhesion of cadmium-tellurium oxides to substrate surface. In turn, ZnO previously prepared electrochemical etching form rough textured addition, an annealing mode used in oxygen stream complete oxidation process heterostructure The resulting nanocompo...

The zinc oxide (ZnO) nanowire arrays on the indium tin oxide (ITO) glass substrates were fabricated by using the two-step hydrothermal method. A high transmittance ~92% of ZnO nanowire arrays on ITO substrate in the visible region was obtained. It was observed that the liquid crystal (LC) directors were aligned vertically to the (ZnO) nanowire arrays. The properties of ZnO nanowire arrays as ve...

Kattel et al (Reports, 24 March 2017, p. 1296) report that a zinc on copper (Zn/Cu) surface undergoes oxidation to zinc oxide/copper (ZnO/Cu) during carbon dioxide (CO2) hydrogenation to methanol and conclude that the Cu-ZnO interface is the active site for methanol synthesis. Similar experiments conducted two decades ago by Fujitani and Nakamura et al demonstrated that Zn is attached to format...

This study reports on the synthesis of zinc oxide (ZnO) nanostructures and examines the performance of polymer nanocomposites fabricated using ZnO dispersed in polymer host matrices. The polymer matrix used was an epoxy based thermosetting polymer known as Diglycidyl Ether of Bisphenol-A(DGEBA). Zinc oxide nano particles were prepared by precipitation method using Poly Vinyl Alcohol as the surf...
