“…It is well-known that the crystal quality can be evaluated using the crystallite size, where the full width at half maximum (FWHM) is inversely proportional to the crystal size in accordance with Debye-Scherrer's module. 29 The results demonstrate an increase in the crystallite size as the concentration increases, which in turn indicates a better crystal quality of the prepared nanoparticles at 10 mm concentration (Figure 1b).…”

In this article, a simple new technique for the green synthesis of copper oxide nanoparticles (CuO NPs) using peroxidases oxidoreductases (POX) enzyme extracted from fig leaves for antifungal and antibacterial activities has been reported. Subsequently, a comprehensive investigation of the structural, optical, and morphological properties of the synthesized CuO NPs was elucidated, using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Electrodiagnostic (EDX), atomic force microscopy (AFM), and transmission electron microscopy (TEM) analysis techniques. Specifically, the resultant nanoparticles are spherical with a diameter ranging from 28–68. CuO NPs were further tested for their antifungal activity against Candida and Aspergillus species, while the antibacterial activity was screened in contradiction of pathogenic bacterial strains namely gram-positive Staphylococcus aureus and gram-negative Asinobacterial species. The present study reveals a convenient use of POX fig leaves extract as fuel, for the well-organized synthesis of CuO NPs via green synthesis technique to acquire considerably active antifungal and antibacterial materials.

“…The photoluminescence (PL) spectra of FAPbI 3 are investigated with a PL CARY ECLIPSE under a 405 nm excitation wavelength. 40 The Edinburgh system (FLS980 spectrofluorometer) excited with pulsed laser excitation at 510 nm and a repetition rate of 1 MHz is used to collect time-resolved PL (TRPL) decay responses of FAPbI 3 films. To record current density− voltage (J−V) curves of FAPbI 3 PSCs, they were exposed to a simulated irradiation of AM 1.5 G, and their J−V responses are measured with a 2400 Keithley instrument with a voltage step of 50 mV/s.…”

It is essential and challenging to develop green and cost-effective solar cells to meet the energy demands. Solar cells with a perovskite light-harvesting layer are the most promising technology to propel the world toward next-generation solar energy. Formamidinium lead tri-iodide (FAPbI 3 )-based perovskite solar cells (F-PSCs), with their considerable performance, offer cost-effective solar cells. One of the major issues that the PSC community is now experiencing is the stability of α-FAPbI 3 at relatively low temperatures. In this study, we fabricated FAPbI 3 −PSCs using cyclohexane (CHX) material via a two-step deposition method. For this purpose, CHX is added to the formamidinium iodide:methylammonium chloride (FAI:MACl) solution as an additive and used to form a better FAPbI 3 layer by controlling the reaction between FAI and lead iodide (PbI 2 ). The CHX additive induces the reaction of undercoordinated Pb 2+ with FAI material and produces an α-FAPbI 3 layer with low charge traps and large domains. In addition, the CHX-containing FAPbI 3 layers show higher carrier lifetimes and facilitate carrier transfer in F-PSCs. The CHX-modified F-PSCs yield a high champion efficiency of 22.84% with improved ambient and thermal stability behavior. This breakthrough provides valuable findings regarding the formation of a desirable FAPbI 3 layer for photovoltaic applications and holds promise for the industrialization of F-PSCs.

“…Nanoparticles and nanobiomedicine provide an alternative pathway to overcoming the addressed typical antibiotic limitations due to excellent biocompatibility, high antimicrobial activity, and good thermal stability of the nanoparticles (9,10). Several nanoparticles, ZnO in particular, delivers an outstanding antimicrobial performance in a wide range of bacteria such as Escherichia coli and Staphylococcus aureus (9,11). Furthermore, ZnO has demonstrated some attractive applications such as solar cells, catalysts, photodetectors, and biomedical/antibacterial activity (12,13,14,15).Herein, the interaction between the bacteria and ZnO nanoparticles are highly effective if the ZnO is prepared using a biological method due to the absence of undesired/toxic chemical compounds.…”

This study was aimed to demonstrate the biosynthesis procedure of Zinc oxide nanoparticles (ZnO NPs) using Prodigiosin pigment which in turn produced from particular environmental bacteria isolates Serratiamarcescensas a stabilizing and reducing agent. Additionally, the synthesis conditions were precisely taken into consideration as a pH of 7 and a temperature of 50°C alongside a concentration of prodigiosin of 12 mg/ml with 5mg precursor of zinc acetate in deionized distilled water (DDW) 50ml. Biosynthesized ZnO nanoparticles have presented many applications such as catalysis, biosensing, anticancer, and biomedical, etc. The optimum condition for ZnO biosynthesis was characterized through several techniques such as UV-Vis, AFM, XRD, FT-IR, and FE-SEM. In particular, a cut-off phenomenon of the biological synthesized ZnO was found at around 280 nmusing UV-Vis, while spherical shape particles were noticed using FE-SEM techniques. Also, the AFM analysis revealed that ZnO NPs an average diameter size of 45.02 nm.And the effect of ZnO NPs on bacteriaPseudomonas aeruginosaon an inhibition zone 29mm.
