The present study reports, the synthesis of ZnO-bentonite nanocomposite by the incorporation of ZnO with bentonite clay. The nanocomposite was characterised by XRD and SEM. ZnO-bentonite was effectively used for removal of Methylene Blue (MB). Removal of MB takes place by photocatalytic degradation and adsorption. Photocatalytic degradation of MB occurs by advanced oxidation process. The factor...

Electrospinning is a versatile technique, which can be used to generate nanofibers from a rich variety of materials. We investigate the variation of a zinc oxide (ZnO)-polyvinylpyrrolidone (PVP) composite structure in morphology by electrospinning from a series of mixture solutions of ZnO sol-gel and PVP. Calcination conditions for the crystallization of ZnO nanofibers and removal of the PVP co...

In the present study we have investigated the effect of zinc oxide (ZnO) nanoparticles on the fiber diameter, fiber morphology, antibacterial activity, and enhanced cell proliferation of the electrospun polycaprolactone (PCL) non-woven membrane. The effect of the ZnO nanoparticle concentration on the fiber diameter and fiber morphology was investigated using a scanning electron microscope (SEM)...

The present investigation depicts the development of a simple and low cost method for the removal of color from textile dyeing and printing wastewater using ZnO as photocatalyst supported with porous activated carbon (AC). Photocatalytic degradation studies were carried out for water soluble toxic alizarin cyanin green (ACG) dye in aqueous suspension along with activated carbon (AC) as co-adsor...

A laboratory trial was conducted to determine whether suspensions of ZnO nanoparticles (ZnO NPs) could interfere with the early growth of fenugreek. This plant species is one of the recommended species by Organization for Economic Cooperation and Development (OECD). Nine concentrations of ZnO NPs (10, 50, 100, 500, 1000, 2000, 3000, 4000, and 5000 mg/L) were prepared in deionized )DI( water (co...

Here, highly transparent, conductive, and stable ZnO/Ag/ZnO electrodes on transparent rigid glass and flexible substrates were prepared by facile, room-temperature magnetron sputtering, in which the continuous Ag layers were obtained by means of oxidization-induced effect under an Ar atmosphere with tiny amounts of O2. The results showed an appropriate amount of O2 was beneficial to form contin...

To research the relationship of micro-structures and antibacterial properties of the titanium-doped ZnO powders and probe their antibacterial mechanism, titanium-doped ZnO powders with different shapes and sizes were prepared from different zinc salts by alcohothermal method. The ZnO powders were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), u...

An aqueous solution-based doping strategy was developed for controlled doping impurity atoms into a ZnO nanowire (NW) lattice. Through this approach, antimony-doped ZnO NWs were successfully synthesized in an aqueous solution containing zinc nitrate and hexamethylenetetramine with antimony acetate as the dopant source. By introducing glycolate ions into the solution, a soluble antimony precurso...

ZnOfilmswith thickness of 80 nmwere grownbypulsed laser deposition (PLD) onMgO (100) single crystal and amorphous fused silica (FS) substrates. Structural studies of ZnO films and a high quality reference ZnOsingle crystalwereperformedby slowpositron implantation spectroscopy (SPIS). Itwas found that ZnO films exhibit significantly higher density of defects than the reference ZnO crystal. Moreo...

In the emerging issue of increased multi-resistant properties in food borne pathogens, zinc oxide (ZnO) and nano-particle zinc oxide (nano-ZnO) are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of nano-ZnO towards pathogens microbes Bacillus subtilus NRRL B-543, Bacillus megaterium ATCC 25848, Staph...
