The rapid development in nanoparticle production and application during the past decade requires an easy, rapid, and predictive screening method for nanoparticles toxicity assay. In this study, the toxicological effects and the source of toxicity of copper nanoparticles (CuNPs) are investigated based on a stress-responsive bacterial biosensor array. According to the responses of the biosensing ...

The biological synthesis of nanoparticles with copper, silver, and zinc (Cu, Ag, Zn) is reported in this study, adopting a greener, safe, reliable, eco-friendly approach by using an aqueous leaf extract Catharanthus roseus. synthesised trimetallic were characterised different characterisation techniques. UV–visible spectroscopic technique was initially used to assess nanoparticle formation, whi...

Nanocomposite lead-free solders are gaining prominence as replacements for conventional lead-free solders such as Sn-Ag-Cu solder in the electronic packaging industry. They are fabricated by adding nanoparticles such as metallic and ceramic particles into conventional lead-free solder. It is reported that the addition of such nanoparticles could strengthen the solder matrix, refine the intermet...

cu2o nanoparticles were synthesized by thermal treatment in liquid paraffin without any inert gas protection using nano structures of schiff base copper (ii) complex (1) as precursor. liquid paraffin was used as solvent and reductant. span 80 was applied to control the morphology of cuprous oxide nanoparticles. the nano structure of the complex was characterized by x-ray diffraction measurement...

the selective reduction of oximes with sodium borohydride (nabh4) in the presence of nano cu and charcoal was investigated. cu nanoparticles are widely used as catalysts; efficacious catalyst: copper and copper alloy nanometer feature high efficacy and selectivity, and can be used as catalyst in some reactions. we have shown that nabh4 in the presence of charcoal is an efficient protocol for th...

The hybrid nanofluid is formed when more than one type of nanoparticle used in the preparation process. study nanofluids most recent trend, as they have potential to improve greener energy production. Solar thermal systems still require further research before can be widely used. As a result, current uses mono CuO and + Cu/water working fluid explore performance an evacuated tube solar collecto...

The objective of this study is to determine the effects coupled deformation and irradiation extremes on Ta phase evolution in Cu-10at.%Ta nanocomposite. Heterophase nanocomposites with positive heat mixing offer exceptional mechanical properties, high temperature performance, tolerance. Here, we consider cooperative stability using transmission electron microscopy mapping during interrupted sit...
