“…The most intense peak was observed at (100) and shows the preferred growth plane; therefore, it demonstrated to the high level of purity of ZnO NP products. The XRD pattern of green synthesized ZnO NPs reported in the literature [14] is incongruous in accordance with the trend illustrated in Figure 2. Thus, utilizing XRD, the formation of ZnO NPs was established.…”

“…The immersion duration of ZnO NPs together into sensitizing dye had been demonstrated to be an important factor in the solar cell properties of the ZnO-based DSSC [34]. When compared to similar research [12][13][14][15], the manufactured ZnO-based DSSC showed better performance in a lesser period of sinking time [35][36][37][38][39][40][41][42][43][44]. The enhanced absorption due to the larger amount and the better performance can also be expressed by the dye molecules that have been adsorbed onto the ZnO surface which can also expressed the better performance.…”

“…where t is the mean dimension of nanoparticles, k is the frequency of radiation, β is the whole width half peak in radians, and θ is the degree diffraction [12][13][14]. Onion, cabbage, carrot, and tomato preparations have been used to synthesize nanoparticles with mean sizes of 17 nm, 18 nm, 24 nm, and 15 nm, respectively.…”

The production of zinc oxide nanoparticles (ZnO NPs) utilizing different vegetable extracts (onion, cabbage, carrot, and tomato) was performed in this research owing to its excellency over other methods of synthesis, namely, simplicity, environmental friendliness, and the elimination of harmful compounds. Fresh extracted onion, cabbage, carrot, and tomato of ZnO NPs are characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-visible spectroscopy. FTIR findings demonstrate that the prepared nanoparticles were observed in the spectrum of 626 cm-1–1219 cm-1 with some other functional groups. Wurtzite hexagonal structure of the prepared ZnO NPs was observed from XRD results. In addition, the prepared nanoparticles were failed into nanoscales (17 nm, 18 nm, 24 nm, and 15 nm) calculated from Scherrer’s equation. Nearly spherical shapes were seen from SEM image for onion and tomato extraction while rod and tube for carrot and cabbage, respectively. Two broad peaks were observed from UV-vis spectroscopy results for each extract. The presence of a wide range of energy bandgaps in the region of 3-4 eV was detected, indicating that ZnO NP material can be employed in metal oxide semiconductor-based systems. The dye-sensitive solar cell based on ZnO NPs has been successfully synthesized, and the efficiency of the device has been evaluated by measuring the current density-voltage behaviour under the presence of artificial sunshine. The increased effectiveness of the manufactured dye-sensitive solar cell is attributable to a large improvement in dye molecular adsorption onto the surface of ZnO NPs. Thus, the usage of the green produced ZnO NPs with creating dye sensitivity solar cell is a simple and viable way for the well-being of our future.

“…Moisture absorption resulted in the two bands near 1437.79 and 3630.44 cm −1 , caused by the HOH stretching and bending vibration mode, respectively 47 . In addition, the strong peak observed at 1552.50 cm −1 is caused by the strong metal‐oxygen bond in ZnO 48 . Other weak bands were seen at 902.75, 864.06, and 687.49 cm −1 .…”

Polymer nanocomposites have placed themselves in a highly favorable position in use in practical applications, with materials currently employed in technology related processes. This is because they have improved chemical, physical, morphological, structural, and mechanical properties compared to their polymer microcomposites counterparts or even neat polymer. In this study, two inorganic nanofillers, namely magnesium oxide nanoparticles (MgO NPs) and zinc oxide nanoparticles (ZnO NPs) were separately incorporated into high-density polyethylene (HDPE) by melt blending technique. The ZnO NPs contents in the nanocomposites were set at 1.0, 2.0, 4.0, and 6.0 wt%, while 2.0, 4.0, 6.0, and 8.0 wt % were used by MgO NPs. A comparative study was conducted between different features of the nanocomposites based on their compositions. Such features included mechanical properties, thermal stability, morphological, and structural properties. The as-prepared nanocomposites were proven to be crystalline as confirmed from the XRD. Based on the SEM, both nanofillers were found homogenously dispersed in the HDPE matrix. DSC confirmed that the melting and crystallization behaviors of all nanocomposites were not significantly influenced by the addition of the nanofillers. Tensile tests were performed to determine elastic modulus, tensile stress at yield, tensile stress at break, along with tensile strain at yield values and tensile strain at break. The collected results revealed that loading 2.0 wt% ZnO NPs in the nanocomposites provided elastic modulus up to 237% compared to the pure HDPE. In the case of MgO NPs, as their loading in the nanocomposites reached 4.0 wt%, the elastic modulus increased to 160%. The tensile stress of synthesized nanocomposites increased up to 35.95 ± 2.09 MPa using 2.0 wt% ZnO NPs-filled nanocomposites and up to 28.15 ± 0.91 using 4.0 wt% MgO NPs. Overall, the 2.0 wt% ZnO/HDPE nanocomposite presented better mechanical characteristics in comparison to other tested nanocomposites in this study.
