Abstract The cobalt oxide nanoparticles (Co 3 O 4 NPs) were synthesized via the green method using Piper nigrum ( P. ) leaves extract and calcined at different temperatures. crystalline nature was studied through x-ray diffractometer (XRD). With increasing calcination, amorphous phase transitioned to phase. Diffuse reflectance spectroscopy (DRS) used observe UV-Visible light absorbance phenomenon, Tauc’s plot calculate band gap energy, which found decrease with calcination. Scanning electron...
Abstract The aim of this study was to explore the antibacterial and antioxidant efficacy nickel oxide nanoparticles (NiO NPs). Raphanus sativus ( R. ) extract mediated NiO NPs were calcined at 100, 300, 600 900 ℃ in a muffle furnace for 3 h. increased intensity diffraction bands X-ray (XRD) spectrum suggest that degree crystallinity increases with increasing calcination temperature. desired elements depicted energy dispersive X-rays (EDX) confirm purity Sample. variation surface morphology...
Heavy metals cause deleterious effects on human health and drastically alter the biogeochemical cycles within freshwater habitats. The main activities leading to heavy metal contamination of various aquatic ecosystems comprise industry, agriculture, urbanization, transport mining. Lake Nasser is source in Egypt, usually polluted from upstream hydrographic basin River Nile. current study surveyed impact (i.e., Cd, Zn, Pb Cu) water, sediment two Nile Tilapia (Oreochromis niloticus) fish organs...
The Pipper nigram (P. nigram) leaf extract was used for the biosynthesis of copper oxide nanoparticles (CuO NPs) and successful formation resultant product confirmed through several physicochemical techniques. chemical structure elemental composition were analysed Fourier transform infrared (FTIR) energy dispersive X-ray (EDX) spectroscopies, respectively. crystalline crystallite size investigated an diffractometer (XRD) a monoclinic with 40.68 nm reported. Even-distributed particles average...
The NiO-ZnO nanocomposite (NiO-ZnO NC) was synthesized by ecofriendly process using Diospyros kaki (D. kaki) extract of leaves as reducing and capping agents. X-ray diffraction (XRD) used for examined crystallinity, cell dimensions, crystallite size (7.6 nm). To determine the purity sample weight percentage, energy dispersive (EDX) is used. surface morphology determined scanning electron microscopy (SEM) transmission (TEM). By Fourier transform infrared spectroscopy (FTIR), functional groups...
Abstract The increasing environmental concerns over wastewater contamination have spurred significant interest in developing efficient and sustainable methods for treatment. In this study, a simple user-friendly approach was employed to synthesize iron oxide nanoparticles (IO-NPs) using Musa acuminata peel extract as reducing stabilizing agent. synthesized IO-NPs were thoroughly characterized transmission electron microscopy, X-ray diffraction, scanning Fourier-transform infrared...
In the current research, we examined effects of warfarin (W1 = 5 mg/L and W2 25 mg/L) tinzaparin (T1 T2 on meiofauna using microcosms. These microcosms were intentionally contaminated with both anticoagulants for one month. The findings indicated that nematodes amphipods demonstrated greatest resistance to two evaluated. Specifically, number increased after exposure treatment included T2. Following separate introduction each drug, displayed a taxonomic restructuring, more significant impact...
The Paeonia emodi (P. emodi)-mediated iron oxide nanoparticles (Fe2O3 NPs) were screened for in-vitro and in-vivo antibacterial activity against the Staphylococcus aureus (S. aureus) (ATCC #: 6538) Escherichia coli (E. coli) #:15224). synthesized Fe2O3 NPs characterized via nitrogen adsorption-desorption process, X-ray diffractometer (XRD), transmission scanning electron microscopies (TEM SEM), energy dispersive (EDX) Fourier transform infrared (FTIR) spectroscopies. SBET was found to be...
The zinc oxide–zirconium dioxide (ZnO-ZrO2) heterojunction was prepared by a green method using rubber leaves as reducing and capping agents. Various physicochemical techniques were used to study the chemical composition structural optical properties of synthesized nanocomposite. nature confirmed through X-ray diffraction average sizes ZnO ZrO2 crystallites found be 70 24 nm, respectively. photocatalytic potential ZnO-ZrO2 examined against rhodamine 6G (Rh-6G), 97.30 percent dye degraded due...
This study was planned to synthesize a multifunctional nanomaterial that can effectively encounter the organic pollutants, multidrug-resistant bacteria and reactive free radicals. The Bergenia ciliate (B. ciliate) leaves extract used as reducing capping agent for synthesis of nickel oxide nanoparticles (NiO NP). physicochemical properties were studied through X-ray diffractometre (XRD), energy dispersive (EDX), scanning electron microscopy (SEM), transmission (TEM), UV-visible Fourier...
Azo dyes in textile industry effluent are one of the major toxic contaminants causing a severe threat to life. Bioremediation is most cost-effective and environmentally beneficial innovative biotechnologically technique used mitigate dyes’ effects aquatic environments.
