Study of structural and magnetic properties of hydro/solvothermally synthesized α-Fe2O3 nanoparticles and its toxicity assessment in zebrafish embryos

Green synthesis of superparamagnetic maghemite nanoparticles using banana pseudo-stem: a reusable heterogeneous catalyst for Fenton-like degradation of tetracycline antibiotics

“…1(b)) is entirely different and has peaks at 2 θ values of 24.19, 33.21, 35.66, 40.99, 49.49, 54.22, 57.71, 62.40 and 64.04 that are characteristic of the (012), (104), (110), (113), (024), (116), (018), (214) and (300) planes of α-Fe 2 O 3 . 21,22 Also, the peaks at 33.21 and 36.66 are the most intense, which is also characteristic of α-Fe 2 O 3 nanoparticles.…”

“…It is evident that all the d-spacings found were much closer to the values of g-Fe 012), ( 104), ( 110), ( 113), ( 024), ( 116), ( 018), ( 214) and (300) planes of a-Fe 2 O 3 . 21,22 Also, the peaks at 33.21 and 36.66 are the most intense, which is also characteristic of a-Fe 2 O 3 nanoparticles. X-ray photoelectron spectra (XPS) were taken to assess the surface chemical composition of the MNPs.…”

Preparation and Conductive and Electromagnetic Properties of Fe3O4/PANI Nanocomposite via Reverse In Situ Polymerization

“…Also, in common magnetic particles, nickel and cobalt are toxic, and their applications are severely restricted in the fields of life science and medicines [13][14][15]. Iron oxide (Fe 3 O 4 , γ-Fe 2 O 3 ) is usually used as a magnetic component, because of its low toxicity (LD 50 about 2000 mg/kg, much higher than the current clinical application dose), availability, and so on [16][17][18].…”

Bi2O3–BiFeO3 Glass-Ceramic: Controllable β-/γ-Bi2O3 Transformation and Application as Magnetic Solar-Driven Photocatalyst for Water Decontamination

“…It is interesting to note that the magnetic properties were found to be significantly dependent on the starting ratio between Fe 2 O 3 and Bi 2 O 3 of the materials rather than the heat-treatment. For instance, all BF samples prepared at different heat-treatment times depict nearly the same hard ferromagnetic behavior with coercivity ( H c ) values of about 750 G and remanent magnetization ( M r ) of 0.16 emu/g (Figure a). A plausible explanation is that BF samples (either the as-prepared or the corresponding glass-ceramics) contain the same crystalline magnetic phases.…”
