This report presents the synthesis of magnesium ferrite (MgFe2O4) by coprecipitation method and its subsequent characterization by using X-ray diffraction (XRD) and Fourier transform infrared...

Activated carbon prepared from sawdust, magnetized by magnetite nanoparticles, was used for the adsorption of crystal violet dye (CV) from an aqueous solution. The nanocomposite Fe3O4/AC was...

2019年10月1日 · In this study for analysis crystallite size, we use the composition 10% AC and 20% AC of nanocomposites Fe 3 O 4 /AC from the XRD (X-ray diffraction) spectra (Shimadzu 7000) with wavelength (λ) 1.54 Å and CuK α radiation (40 kV, 30 mA, step size 0.02 0, scan rate 2 min −1, 25° ≤ 2 θ ≤ 75°)) and also compared by Transmission Electron ...

Our study explored how chitosan and polyethylene glycol (PEG) coatings affect the structural properties, drug-loading efficiency, and anti-cancer efficacy of Fe3O4 nanoparticles (NPs). The...

2015年3月23日 · Here we report a two-step solvothermal method to synthesize the Fe 3 O 4 nanosheets with good magnetochromatic property without deoxygenated protection and controlling of the pH value. In the...

2018年10月3日 · Monodispersed Fe 3 O 4 magnetic nanoparticles (MNPs) having size of 7 nm have been prepared from iron oleate and made water dispersible by functionalization for biomedical applications. Three...

2017年9月1日 · Structure, morphology and optical properties of Fe 3 O 4 nanoparticles were described. Changes in the particle size were confirmed by TEM, XRD, FTIR and UV–vis spectroscopy. Magnetite nanoparticles modified by tartaric acid had the highest value of optical band-gap energy (3.01 eV).

2013年1月1日 · This xerogel was found to be an oxide mixture of Fe 3 O 4 and γ-Fe 2 O 3, which is concluded from its XRD pattern and its black coloration with brown tint. The further heating at 150 °C in the air atmosphere promoted the complete structure transformation of the oxides mixture to γ-Fe 2 O 3 within short time.

2018年7月26日 · The synthesis of Fe 3 O 4 magnetic nanoparticles (MNPs) from iron ore as source of Fe3O4 has been done. Fe 3 O 4 MNPs were characterized by X-ray diffractometer (XRD) and Transmission Electron Microscope (TEM) for phase and size, Fourier Transform Infrared (FTIR) Spectrometer for bonding, and Vibrating Sample Magnetometer for …

Analysis of these nanomaterials using X-ray diffraction (XRD) unveiled discernible peaks in the diffraction pattern, suggesting that the magnetite nanomaterials possess a cubic crystal...
