In this study, we describe the environmentally friendly synthesis of copper oxide (CuO) and its subsequent characterization for use in supercapacitors. Using extracts from dried, finely ground Moringa Oleifera as the reducing/capping agent, we created the... see more

The flower-like Bi2WO6 microsphere was synthesized through a simple hydrothermal route, and three catalysts, Au/Bi2WO6, CuO/Bi2WO6, and Au–CuO/Bi2WO6, were prepared by a deposition–precipitation method. The morphology and structure of the catalysts were c... see more

Abstract Naringenin (NaR) is a flavonoid, mostly found in citrus fruit. Its IUPAC name is 5,7-Dihydroxy-2-(4-hydroxyphenyl)chroman-4-one. Naringenin is lipophilic in nature and possessing antioxidantproperty. In present study,7-Dihydroxy-2-(4-hydroxypheny... see more

In this study, pure crystallographic CuO nanoparticles are successfully synthesized via the sol-gel method through the reduction of copper acetate in water as a solvent. The as-prepared nanoparticles are characterized by X-ray diffraction (XRD), UV-Vis sp... see more

In this paper, the reduction duration of (CuO)x-(NiO)(1-x) and (CuO)x-(Co3O4)(1-x) binary mixtures was studied using thermogravimetric method. The reduction reaction was performed using copper, nickel and cobalt oxides as metal precursors and methane gas ... see more

The anti-bacterial characteristics of different nano-structured metal and metal oxides modified cotton fabrics were investigated. In this study, silver metal, copper, zinc and magnesium oxides have been supported on bleached cotton fabrics. Reduction, wet... see more

Results: The MIC50 value of CuO NPs was determined at the range of 1–10 µg/ml for S. mutans, < 1 µg/ml for L. acidophilus, and 10 µg/ml for L. casei. Higher concentrations of CuO NPs (100-1000 µg/ml) were effective on the bacterial cell ... see more
