The burden of life on the earth is the source of biological contamination in water. Nanotechnology has promising contributions in control of microbial contaminations and medicinal plants further increase these properties. Presently, copper acetate and nickel oxide nanoparticles were synthesized using 1mM solution of each with Ziziphus mauritiana leaves extract as reducing agent. Nanoparticles w...

Nanoparticles are described as substances with at least one exterior dimension between 1 and 100 nm. can be produced by physical, chemical, or biological processes. Nanoparticle production techniques include chemical reduction, electrochemistry, photochemistry, physical vapour condensation. However, some of these methods very expensive risky. The method for creating nanoparticles is simple, qui...

Nanobiotechnogy has been developed to synthesized copper oxide nanoparticle. This was carried out biologically using leaf extract of Psidium guajava as a reducing and stabilizing agent. Optical property showed color change from dark brown gold- yellow after the addition extract. The possible functional group in plant responsible for reduction CuONps identified belonging alkyl halide by FT-IR an...

Interatomic interaction potentials are compared using a molecular dynamics modeling method to choose the simplest, but most effective, model describe of copper nanoparticles and graphene flakes. Three considered: (1) bond-order potential; (2) hybrid embedded-atom-method Morse (3) potential. The is investigated for crumpled filled with determine possibility obtaining composite mechanical propert...

In the recent years, great interest has been devoted to the unique properties of nanofluids. The dispersion process and the nanoparticle suspension stability have been found to be critical points in the development of these new fluids. For this reason, an experimental study on the stability of water-based dispersions containing different nanoparticles, i.e. single wall carbon nanohorns (SWCNHs)...

Graphene, which has a linear electronic band structure, is widely considered as a semimetal. In the present study, we combine graphene with conventional metallic surface-enhanced Raman scattering (SERS) substrates to achieve higher sensitivity of SERS detection. We synthesize high-quality, single-layer graphene sheets by chemical vapor deposition (CVD) and transfer them from copper foils to gol...

One of the most intricate issues of nuclear power is the long-term safety of repositories for radioactive waste. These repositories can have an impact on future generations for a period of time orders of magnitude longer than any known civilization. Several countries have considered copper as an outer corrosion barrier for canisters containing spent nuclear fuel. Among the many processes that m...

Copper Oxide Nanoparticles (CuONPs) show a broad spectrum of antimicrobial activity against various species microorganisms, including gram-positive and gram-negative fungi bacteria, but in general bacteria are more resistant to the effects copper nanoparticle ions than ones. In this work, synthesis oxide nanoparticles has been carried out using laser ablation methods were applied as antibacteri...

The pesticide residues with low concentration are important to detect in food safety. Although a lot of methods, such as spectrophotometry, colorimetry and liquid chromatography, used residues, they often suffer from efficiency long detection time. Here, hybrid Surface Enhanced Raman Scattering (SERS) substrate, namely, Au nanoparticle/copper-based graphene/arrayed cone cavities ([email protect...
