Background and Objectives: Water pollution with oil compounds causes the development of new technologies to eliminate oil pollution. The purpose of this study was to determine the efficiency of synthesized zinc oxide nanoparticles in the adsorption of oil from aqueous media. Materials and Methods: In this laboratory study performed in the summer of 2019, zinc oxide nanoparticles were used as a...
in this research zinc oxide (zno) nano-crystalline powders were prepared by sol-gel method using zinc acetate. the zno nanoparticles were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), ultraviolet-visible (uv-vis), fourier transform infra-red (ft-ir) and energy dispersive x-ray (edx) spectroscopy. the structure of nanoparticles was studied using xrd pattern. the c...
a simple method has been employed to synthesize copper and copper oxide nanoparticles from copper (ii) succinate precursor by thermal decomposition method using oleylamine as a capping agent. the particles synthesized with oleylamine and triphenylphosphine were well dispersed nanoparticles obtained from x-ray diffraction (xrd). the synthesized copper nanoparticles were characterized by uv-visib...
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...
Background: Synthesis of ZnO nanoparticles (ZnO NPs) is very valuable due to their applications in cancer treatment, unique thermal, optical and electronic properties. In this study, green synthesis of ZnO nanoparticles was performed using Allium jesdianum extract. The green synthesis is a successful process that is environment friendly and low-cost as well. Methods: In this study, the extract...
Recently, the rapid emergence of antibiotic-resistant pathogens has caused a serious health problem. Scientists respond to the threat by developing new antimicrobial materials to prevent or control infections caused by these pathogens. Polymer-based nanocomposite hydrogels are versatile materials as an alternative to conventional antimicrobial agents. Cross-linking of polymeric materials by met...
In this study bio-hydrogen and bioethanol were produced from dry biomass of water hyacinth by microbial fermentation under influence of zinc oxide nanoparticles. For fermentative bio-hydrogen production biomass was first pretreated and then saccharified into fermentable sugars by enzymes. Sugars of enzymatic hydrolysis were xylose and glucose with concentration of 9.0% and 8.0% respectively. Fo...
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...
Copper oxide nanoparticles (CuO-NPs) synthesized by an implicitly environmentally benign process using Acanthospermum hispidum L. aqueous plant extract as an effective bio-oxidizing/bio-reducing agent. Phytochemical screening of the fresh aqueous leaves extract showed the presence of coumarins, tannins, saponins, phenols, flavonoids, sterols and volatile oils. Fourier transform infrared spectro...
The present study was performed to evaluate the protective effect of molasses pretreatment on the liver index of common carp (Cyprinus carpio) in exposure to copper oxide and titanium nanoparticles. Therefore, 250 juveniles of common carp for 42 days in four categories, rations without molasses (treatment 1), diets containing 0.5% molasses (treatment 2), diets containing 1% molasses (treatment ...
