Zinc oxide nanostructures – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 21ab31-YTkxO Occurrence and Production In 2011, more than 16 million tons of copper from ore mines are mined. Copper oxide nanoparticles have been of considerable interest due to the role of CuO in catalysis, in high-Tc superconductors [15–18], and in gas sensors [19–21]. Results The typical XRD pattern of theCuO nanoparticles annealed at 300°C is shown in Figure 1. Copper(II)-oxide nanoparticles can be synthesized through different ways, the sizes and shapes of desired nanostructures materials can be controlled by limited number of synthetic factors such as: method, solvents, surfactants, starting precursors temperature….

Herein, starch-protected zero-valent copper (Cu) nanoparticles have been successfully synthesized by a novel facile route. Copper (II) oxide is an important industrial material with many properties such as electrical, optical and so on. Synthesis and optical characterization of copper oxide nanoparticles Amrut. The peak positions of the sample exhibited the monoclinic structure of CuO which was confirmed from the ICDD card No 801916. Synthesis and Characterisation of Copper Oxide nanoparticles ... Synthesis and Characterisation of Copper Oxide nanoparticles www.iosrjournals.org 62 | Page III. Copper, as a red-brown metal, is in high demand with a usage of more than 20 million tons per year. Here, commercially available 40 nm CuO NPs we Environmental Science: Nano 2014 Most Accessed Articles Copper oxide (CuO) nanoparticles were characterised and investigated with respect to potential antimicrobial applications. Copper nanoparticles act as antimicrobial agent in various fields.
The copper is highly toxic to microorganism such as bacteria (E-Coli, Staphylococcus Aureus, Pseudomonas aeruginosa)and non-toxic to animal cells, due to these phenomena it is considered to be an effective bactericidal metal. It can be used as doping material in semiconductors, chemical sensors, biological applications, efficient antimicrobial agents etc.
An extensive research is being conducted on finding out its varied uses and compatibility. Sulfidation is expected to alter the speciation and properties of CuO NPs significantly. Development of improved methods for the synthesis of copper nanoparticles is of high priority for the advancement of material science and technology. Copper pipes © axe olga / fotolia.com. Magnetic properties of the Synthesized Nanoparticles showed a Paramagnetic behavior. Many nanoparticles (NPs) are transformed in the environment, and the properties of the transformed materials must be determined to accurately assess their environmental risk. We report the synthesis of copper oxide (CuO) nanoparticles from Cu(NO3)2 through wet chemical precipitation method. METAL OXIDE NANOPARTICLES Marcos Fernández-Garcíaa and José A.
