“…Tauc plot of Fig.1 (b) determines the optical gap as 2.46 eV. The particle size of the prepared sample 5nm has been assessed from the equation (3) and it is well agreement with HRTEM particle size assessment of the same sample of our earlier report [5]. The presence of bandgap indicates that the prepared lead nanoparticles exhibit strong quantum confinement and confirms their semiconducting nature.…”

This work reports aspect related to semi-conducting nature of nano-sized particles of lead. This attempt finds its semiconducting behaviors elaborately and such advanced insight has so far not been said in literatures. New findings of Pb nanopowder (metal) by optical, fluorescence, cyclic voltammetry and four probe studies are presented in this study. UV-Vis analysis confirms the nano nature of the sample i.e. 5 nm and SPR peak confirms its metallic nature. The successful calculations of band gap, temperature dependent resistance value confirm its semi-conducting nature and explore its potential application in various industries. This work throws some light on and helps further research.

“…Results of the dislocation density calculated from both the formulas are given in Table 5 in the complementary data. The number of unit cell is calculated from (7) Where D is the crystallite size and V is the cell volume of the sample [30].It is observed from these tabulated details, and from Fig. 2, 3 and 4, dislocation density is indirectly proportional to particle size and number of unit cell.…”

Copper (II) Hydroxide nano particles were synthesized via chemical co-precipitation method from Copper Sulphate and Sodium Hydroxide. Structural and compositional properties were characterized by XRD, SEM, FTIR and UV spectroscopy. XRD confirmed the preferential growth of Copper (II)Hydroxide nano particles that width is 33.42nm. The SEM image shows the synthesized Copper (II) Hydroxide show well crystallized particles with plate-like morphology. The FTIR spectrum is used to study the stretching and bending frequencies of molecular functional groups in the sample. From UV spectrum, the band gap of Copper (II) hydroxide nano particles is found to be 4.5 eV. From AAS studies, it is found that the absorbance is directly proportional to the concentration. The linear fit indicates that Copper (II) Hydroxide nanoparticles have been distributed in proper proportion.

Objective: To optimize and synthesize eco-friendly and low-cost silver nanoparticles (AgNPs) by using gallic acid (GA) reducing agent in bentonite/starch bio-nanocomposites (BNCs) for oral use and to evaluate its antibacterial and anticancer efficacy.Methods: An artificial neural network (ANN) model was employed for the optimization and evaluate the effect of the formulation variables on the entrapment efficiency (EE) of AgNPs. The synthesized AgNPs in BNCs were characterized using UV-vis spectroscopy, energy dispersive X-ray spectroscopy (EDXA), dynamic light scattering (DLS), scanning electron microscopy (SEM), zeta potential and fourier transform infrared spectroscopy (FTIR). Elemental ion analysis was carried out using inductively coupled plasma mass spectrometry (ICP-MS). Drug release study was carried out. The antimicrobial efficacy determined by agar well diffusion method. In vitro anticancer efficacy of AgNPs in breast cancer cell line (MCF-7) by MTT assay was performed.Results: The formation of AgNPs was confirmed by UV-vis absorbance peak shown at 412 nm. XRD spectrum has indicated the face-centered cubic structure of the synthesized AgNPs. SEM and DLS measurements showed spherical nanoparticles with a mean size of 68.06±0.2 nm. The negative surface zeta potential with-32±0.25 mV has indicated colloidal stability of nanoparticles. FTIR spectra confirmed no interaction observed between drug and excipients. AgNPs showed significant EE with 80±0.25%. The synthesized AgNPs in BNCs is a potential candidate for inhibiting the growth of pathogenic bacteria and showed significant cytotoxicity against MCF-7 cancer cell line with IC50 of 160±0.014μg/ml.Conclusion: The present research confirms that the green synthesized AgNPs in BNCs can be a promising antibacterial and anticancer agent regarding stability, low cost and easy preparation.
