“…For the purpose of calculating the photodissociation constant of polymer films in the presence of the nano-added material, by drawing the relationship between ln (A∞ -At) with the irradiation time as shown in Figures (8) to (10). We get a straight line, and this indicates that the optical fractionation reaction of the nickel oxide nanoparticle is a first order reaction.…”

In this study, nickel oxide nanoparticles (NiONPS) were made using a plant extract from the bambar plant, and their identification and effects on the optical characteristics of polycarbonate flakes with a thickness of (60 ±5) microns were also studied. After numerous concentrations of the produced nanoparticles (0.03, 0.06, 0.12, 0.24, and 0.48) % were added to the polymer solution, the degree of photolysis of polycarbonate was evaluated. The prepared nickel oxide nanoparticles (NiONPS) were examined using an atomic force microscope (AFM), which revealed that the average diameter of the particles was 32.54 nm, a scanning electron microscope (SEM), which revealed the size of nanoparticles (17.80-19.08 nm), and X-ray diffraction (XRD), whose results were consistent with the standard reference (JCPDS, No.01-073-1523). Following the irradiation procedure on the polymeric films, the dissociation constant (Kd) and carbonyl group growth coefficient (FT-IR) were calculated using UV-Visible spectroscopy at the wavelength (300) nm, respectively (ICO). A viscometer was also used to calculate the polymer's molecular mass rate, degree of dissociation (α), and numerical rate of severing the polymeric chain (S).

The study investigates the potential of Rhizoclonium hieroglyphicum as a novel source for synthesizing nickel oxide nanoparticles (RH‐NiONPs) and evaluates its biological applications. Phytochemicals in the algal extract serve as capping, reducing and stabilizing agent for nickel oxide nanoparticles. The process variables were optimized using BBD based RSM to obtain maximum RH‐NiONPs. Characterization of RH‐NiONPs using UV–Vis and FT‐IR spectroscopy reveals the plasmon resonance peak at 340 nm and the functional groups responsible for reduction and stabilization. XRD confirmed the crystalline nature while the stability and size of the RH‐NiONPs were determined by DLS and zeta potential. Toxicity assessments demonstrated the effect of RH‐NiONPs against Vigna radiata, Allium cepa and Artemia salina was low. RH‐NiONPs revealed significant zone of inhibition against the selected bacteria and fungi. The results of larvicidal activity showed that RH‐NiONPs are toxic to 4th instar larvae of Daphnis nerii. Also, RH‐NiONPs efficiently decolorized Reactive Violet 13 (92%) under sunlight irradiation and the experimental data well fits to Langmuir isotherm along with pseudo second order kinetic model. The thermodynamic studies enunciate the exothermic and non‐spontaneous photocatalytic decolorization of reactive violet 13. Thus, the current study assesses the eco‐friendly and cost‐effective nature of RH‐NiONPs along with its biological applications.
