In this study, rosemary leaf extract was effectively used to synthesize cobalt oxide nanoparticles (Co3O4 NPs) using a rapid, low-cost, and environmentally friendly approach. The prepared Co3O4 NPs were examined various analytical techniques. However, UV spectrum analysis displayed two sharp absorption peaks at ~350 745 nm. dynamic light scattering zeta potential measurements evaluate the particle size effective stabilization of synthetic in suspensions. A semi-triangular pyramidal shape...
Cd(II) heavy metal is an extremely dangerous hazardous material for both humans and the environment. Its high toxicity reason behind examination of new techniques detecting very small concentrations Cd(II). Recently, Quartz Crystal Microbalance (QCM) has been one that have widely used to detect trace ions in solutions. It a simple, inexpensive, portable, sensitive gravimetric sensor due its quality sensitivity lowest nanograms. In this work, Cuprospinel nanoparticles were synthesized through...
Pb(II) is a significant contaminant that known to have negative effects on both humans and animals. Recent industrial operations exacerbated these consequences, their release of several contaminants, including lead ions, has drawn attention the potential human health. Therefore, there lot interest in rapid, accurate, selective detection ions various environmental samples. Sensors-based nanomaterials are class among many tools methods developed applied for such purposes. novel green...
In the current study, copper oxide nanoparticles (CuO NPs) were synthesized using chia seed extract in a simple, rapid, and eco-friendly manner for first time. The CuO NPs characterized different analytical techniques. images of field emission scanning electron microscopy revealed that triangular pyramid structure, with mean particle size 61.5 nm. absorption peak was measured ultraviolet-visible spectroscopy recorded at wavelength 291 results energy-dispersive X-ray analysis confirmed...
Magnetite Fe3O4 and spinel (2:1) (4:1) NiFe2O4 magnetic nanoparticles (MNPs) were prepared by simple affordable co-precipitation methods using an extract of star anise (Illicium verum) as a green reducing agent. The morphology chemical composition these MNPs confirmed field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, UV–visible diffraction (XRD). synthesized magnetite in the size range 0.1–1 µm. had irregular clustered platelets (magnetite Fe3O4) pyramidal...
The main aim of this study was to prepare antimicrobial nanocomposites consisting alginate, chitosan, and camptothecin (CPT). CPT-loaded calcium alginate (Ca-Alg2) alginate/chitosan (Ca-Alg2-CH) nanomaterials were synthesized characterized using infrared (IR) spectroscopy, X-ray diffraction (XRD), UV-Vis scanning electron microscopy (SEM). activity the genetic effects Ca-Alg2/CPT Ca-Alg2-CH/CPT on Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia studied. repetitive element...
The voltammetric (CV and DPV) behavior of multi-walled carbon nanotube/Nafion composite coupled with a glassy electrode was investigated for the determination 2,4-dichlorophenol. structural morphological evaluation by XRD FESEM revealed that acid treated MWCNT retained their morphology without any change. existence possible functional groups FTIR Raman spectroscopy. Compared to bare GCE, significantly reduced interfacial charge transfer resistance noticed MWCNT/Nafion/GCE electrochemical...
Methylene blue (MB) dye is a common colorant used in numerous industries, particularly the textile industry. When methylene discharged into water bodies without being properly treated, it may seriously damage aquatic and human life. As result, variety of methods have been established to remove dyes from aqueous systems. Thanks their distinguishing features e.g., rapid responsiveness, cost-effectiveness, potential selectivity, portability, simplicity, electrochemical provided promising...
