“…With the 4000X magnification, semi-spherical grains of CuO can be well defined. Similar morphologies were reported in previous research such as in [24] where CuO particles were prepared via chemical precipitation method using Copper (II) chloride dehydrate as a precursor and annealed at 600 o C. Sample P20 corresponds to a PEG wt% = 20% of the total solvent weight percentage. According to [25], a porous structure can be obtained after the coat heat treatment where full vaporization of PEG chain structure takes place leaving cavities behind.…”

Solar energy harvesting is of a great interest lately as it's a clean and environmentally friendly energy source. Therefore, Solar selective coatings development became one of the pioneering research routes nowadays. Copper oxide based films were prepared by a sol-gel route and deposited on a stainless steel substrate via dip coating. The solution was prepared with several concentrations of polyethylene glycol as a surfactant and agglomeration controlling agent. The effect of several concentrations on the optical properties was studied. The microstructure of the coats was discussed in details reflecting on the optical properties as well. In general, the copper oxide based coats have shown uniform and dark visual appearance with acceptable adherence. The coats have been successfully prepared and analysed with a promising absorptivity up to 96.3% with an optical band gap that varies between 2.5eV and 3.03eV.

“…The elemental analysis conrmed that the synthesized sample was CuO, which is in a good agreement with the results of XRD and the literature. 43,44 The average crystallite size of the CuONPs derived from XRD measurements was about 13 nm from XRD data while their average hydrodynamic diameter measured by DLS was about 93 nm with a surface charge around +37 mV as presented in Fig. S2 and S4 (ESI †).…”

The synthesis of copper nanoparticles (CuNPs) using Wrightia tinctoria (Wt) R.Br extract is defined in this article as being convenient, environmentally friendly, and non-toxic. UV-visible spectrophotometry, FT-IR, XRD, particle size analyser, SEM-EDAX and TEM methods were used to describe the physicochemical properties of Wt extract mediated synthesized CuNPs (Wt-CuNPs). The Wt-CuNPs synthesized was found to be monodispersed and spherical, with an average size of 15 nm. Gas chromatography and mass spectrometry (GC-MS) research revealed that the Wt R.Br plant extract contains various phytochemical compounds. The properties of Wt-CuNPs were verified by the findings of characterization tests. Via in silico molecular docking experiments with established targets, the underlying mechanisms of cytotoxicity against breast cancer and larvicidal behaviour against Aedes aegypti of Wt-CuNPs were investigated. Interestingly, in vitro cytotoxicity studies showed 50% cell death (IC 50 ) of Wt-CuNPs treated MCF-7 cells and Vero Cells (Kidney epithelial cells) were displayed at 119.23 μg.mL À1 and 898.75 μg.mL À1 , respectively. Also, Wt-CuNPs showed least LC 50 and LC 90 values for larvicidal activity against A. aegypti were of 32.10 μg.mL À1 and 21.70 μg.mL À1 , respectively. Furthermore, Wt-CuNPs is found to be less toxic and biocompatible in haemolytic assays. The findings clearly showed that biosynthesized Wt-CuNPs have been used as a possible anticancer and larvicidal agent, as well as being environmentally friendly.
