In biomedical applications, Cu 2 O nanoparticles are of great interest. The bioengineered route is ecofriendly for the synthesis of nanoparticles. Therefore, in the present study, there is an attempt to synthesis of Cu 2 O nanoparticles using Datura metel L. The synthesized nanoparticles were characterized by UV-Vis, XRD, and FT-IR. UV-Vis results suggest the presence of hyoscyamine, atropine in Datura metel L, and also, nanoparticles formation has been con rmed by the presence of absorption peak at 790 nm. The average crystallite size (19.56 nm) obtained by XRD. Further, the various functional groups have been con rmed through FT-IR. To highlight the peak of the dominant frequencies, Fourier Power Spectrum was also used to analyze the synthesized nanomaterials spectrum results. Density functional theory (DFT) further also used over a period of time to measure the energy of the substance, which seems to suggest a stable compound. Furthermore, the calculated energies, thermodynamic characteristics (such as enthalpies, entropies, Gibbs-free energies), modeled structures of complexes, crystals, and clusters, and predicted yields, rates, and regio-and stereospeci city of reactions were in good agreement with the experimental ones. Overall, the ndings indicate the successful synthesis of Cu 2 O nanoparticles using Datura metel L.correlates with theoretical study.

The current investigation address the Alternating current (AC) electrical properties, electrochemical characteristics on biopolymer as Withania somnifera leaf extract incorporated sodium alginate polymer lm prepared by solution casting method. Some crystallinity along with amorphous nature of sodium alginate emerged due to the incorporation of Withania somnifera leaf extract. The more amount of strain occurred in crystallization provides broaden peak in X-ray Diffraction (XRD) pattern. With aid of guluronic and mannuronic acids in sodium alginate making hydroxyl bond formation with leaf extract due to the cross linking process can be analyzed from Fourier transform Infrared Spectroscopy (FTIR). At room temperature, the prepared 5 ml of leaf extract incorporated sodium alginate lm has demonstrated highest ionic conductivity in the typical value of 2.80×10 -6 S/Cm. The electrochemical window of the prepared polymer lm in the range of -0.4 to 0.4 V suggesting that used as an electrolyte for supercapacitor applications.
