Zinc oxide nanostructures are deposited on glass substrates in the presenceof oxygen reactive gas at room temperature using the radio frequency magnetronsputtering technique. In this research, the effects of zinc oxide sputtering pressure on thenanostructure properties of the deposited layer are investigated. The deposition pressurevaries from 7.5 to 20.5 mTorr. AFM resu...
Background and purpose: Chrophenols represent one of the most abundant toxic compounds of industrial which are resistant to biodegradation and persist in the environment for long time. Sunlight is the source of many photochemical reactions. The present study aimed to determine degradation of 4-chlrophenol as persistent organic compound by sunlight in the presence of zinc oxide as a catalyst. M...
Background and Aim: Lesions of the skin can impair its vital function to protect humans against external pathogens. Therefore, producing a suitable wound dressing to repair injuries is always one of the challenges of researchers. The present study aims to Synthesize a hydrogel film for wound dressing applications. Methods: In this research, a hydrogel film of polyvinyl alcohol / hyaluronic a...
Silver doped zinc oxide nanoparticles are synthesized by a solution combustion method. The samples characterized by a variety of spectroscopic and other techniques clearly reveal the presence of silver nanoparticles as well as silver clusters. The silver in the two forms was identified by careful deconvolution of X-ray photoelectron spectral results. Their formation was also confirmed by the pr...
BACKGROUND Antibiotic resistance is a global issue that threatens public health. The excessive use of antibiotics contributes to this problem as the genes of antibiotic resistance can be transferred between the bacteria in humans, animals and aquatic organisms. Metallic nanoparticles could serve as future substitutes for some conventional antibiotics because of their antimicrobial activity. The...
Background and Objectives: The advancement of nanotechnology has made it more important to study the destructive effects of nano-materials on organisms. Titanium dioxide and zinc oxide nanoparticles can enter the body in different ways and cause damage to the liver and other organs of the body. The purpose of this study was to evaluate the effects of zinc oxide and titanium dioxide nanoparticle...
Growth and electrochemical properties of single-crystalline vanadium pentoxide (V2O5) nanorod arrays were investigated. Vanadium pentoxide nanorod arrays were grown by electrochemical deposition, surface condensation induced by a pH change and sol electrophoretic deposition. Uniformly sized vanadium oxide nanorods with a length of about 10 mm and diameters of 100 or 200 nm were grown over a lar...
Zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in Hypericum perforatum cell suspension culture. High performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in H. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...
Studies were carried out to evaluate the initially preformed density and initial aspect ratio on the densification behavior of sintered Zinc and Zinc Oxide composite. The preform possessed 0.85 is the initial density. Aspect ratio for three different oxidizing temperatures (at 150°C, 200°C and 250°C) varied from 0.4 to 0.85. Properties of Zinc-Zinc Oxide composites with respect to linear strain...
