Abstract Background The current study was conducted to find out an eco-friendly and cost-efficient way prepare copper nanoparticles (CuNPs) by utilizing Grewia asiatica L. leaf extract, which found be a very effective antimicrobial larvicidal chemical. Methods Characterization of also carried Fourier transform infrared spectroscopy (FTIR) analysis, scanning electron microscope along with X-ray ...

Understanding the relationship between the location of nanoparticles (NPs) in an organic matrix and their catalytic performances is essential for catalyst design. Here we show that catalytic activities of Au, Ag and CuNPs stabilized by dendrimers using coordination to intradendritic triazoles, galvanic replacement or stabilization outside dendrimers strongly depends on their location. AgNPs are...

in order to examine the effects of silver, zinc, nickel, zinc- copper nanoparticles on germination, seedling establishment, and enzyme activity of alfalfa seeds, a factorial experimental was conducted in a randomized complete design with three replications in the seed laboratory, college of agriculture and natural resources, university of tehran in karaj. the objective of this study was to dete...

Ag is abundant in nature and employed practically every aspect of life. Furthermore, Ag+ contamination poses a severe hazard to human environmental health due the extensive usage products. Traditional detection techniques include drawbacks such as high operational costs, sophisticated operating units instruments, strong technical demands. The use fluorescence copper nanoparticles pollution has ...

Bacterial blight in Anthurium andraeanum Lind. which is caused by Xanthomonas sp. regarded as the most threatening disease anthurium industry worldwide. Therefore, current study was carried out to determine whether application of copper nano particles (CuNPs) and sulfur nanoparticles (SNPs) a possible solution control bacterial anthurium. The bacterium isolated using standard methods single col...

The effect of topical application of copper and zinc nanoparticle suspensions on the dynamics of bacterial contamination of the experimental purulent wound was studied. A model of purulent wound infected with polyantibiotic-resistant clinical strains of Staphylococcus aureus isolated from orthopedic trauma patients was obtained in 30 white male rats. The use of copper nanoparticle suspension en...

Comparative analysis of copper nanoparticles (CuNPs) obtained by electrodeposition on highly oriented pyrolytic graphite (HOPG) substrates from different supporting electrolytes containing sulphate anions, was performed. Voltammetric results indicated that Cu follows a diffusion-controlled nucleation and crystal growth model for three solutions studied (Na2SO4, H2SO4 Na2SO4+H2SO4). Na2SO4 solut...

A new approach for the synthesis of zero-valent copper nanoparticles (CuNPs) supported on ordered mesoporous silica SBA-15 and SBA-16 by using vegetal antioxidants, coffee Robusta green tea was developed in present work. Diverse characterization techniques such as X-ray diffraction, nitrogen adsorption–desorption, transmission electron microscopy, thermogravimetric analysis, Fourier transform i...

In this report is discussed a novel, easy, and general synthesis method to prepare zerovalent iron (ZVI) and copper (ZV Cu) nanoparticles (NPs), from colloid dispersions in an environmental friendly organic solvent, ethylene glycol (EG). Conventional metallic salts are used as nanoparticle precursors; sodium borohydride (NaBH4) is the reducing agent, and triethylamine (TEA) is used as the nanop...
