Copper oxide (CuO) nanoparticles (NPs) are abundant in manufacturing processes, but they an airway irritant. In vitro pulmonary toxicity of CuO NPs has been modeled using cell lines such as human bronchial epithelial line BEAS-2B. 2D culture, BEAS-2B undergoes squamous differentiation due to the presence serum. Differentiation is part repair process lung cells vivo that helps preserve lining re...

Bergenia ciliata (B. ciliate) leaf extract was used as a capping and stabilizing agent to synthesize copper oxide nanoparticles (CuO NPs). The selection of B. ciliate is purely based on its rich phytochemical composition less utilization in green chemistry. X-ray diffraction (XRD) analysis showed that the CuO NPs were found be highly crystalline, while irregular morphology other structural prop...

Room temperature ferromagnetism (RTF) is observed in pure copper oxide (CuO) nanoparticles which were prepared by precipitation method with the post-annealing in air without any ferromagnetic dopant. X-ray photoelectron spectroscopy (XPS) result indicates that the mixture valence states of Cu1+ and Cu2+ ions exist at the surface of the particles. Vacuum annealing enhances the ferromagnetism (FM...

In the present study, tenorite (CuO) nanoparticles have been assayed for their catalytic properties. The decontamination reaction of chloro ethyl ethyl sulfide (CEES) as an surrogate of sulfur mustard simulant have been accomplished on the surface of CuO NPs with different weight ratios at ambient temperature and monitored by Gas chromatography equipped with Flame ionization detector (GC-FID) a...

Copper oxide nanoparticles (CuO NPs) were synthesised with laser ablation of a copper sheet immersed in deionized water (DW), cetrimonium bromide (CTAB), and sodium dodecyl sulphate (SDS), respectively. The target was irradiated pulsed Nd: YAG at 1064 nm, 600 mJ, pulse duration 10 ns, repetition rate 5 Hz. CuO NPs colloidal analyzed using UV–Vis spectroscopy, the Fourier transform infrared (FTI...
