Stabilization of temperature during magnetic hyperthermia by Ce substituted magnetite nanoparticles

Rare‐Earth Doped Iron Oxide Nanostructures for Cancer Theranostics: Magnetic Hyperthermia and Magnetic Resonance Imaging

“…Similar observations have been reported in several such doped magnetite studies involving other RE ions. [70,71,77,79,80,82,85,100,105] However, due to the relatively large radius, the d-spacing could be expanded by doping. One such example is Y 3+ doping in Fe 3 O 4 , as shown in Figure 3B.…”

“…Impurities at substantially higher doping percentages were also reported for other RE doped magnetite systems. [80,105] Generally, no impurities could be observed at the doping concentration, suggesting all the dopants enter parent Fe 3 O 4 lattice sites. [32,42,80,98] Another interesting aspect of Gd doping is its effect on crystallite size, as it increases substantially with an increased doping concentration.…”

[32,42,80,98] Another interesting aspect of Gd doping is its effect on crystallite size, as it increases substantially with an increased doping concentration. [42] For less than 1 at% doping, no much change in crystallite size as compared to the undoped counterpart could be detected from XRD analysis.…”

Iron Species-Supporting Hydrophobic and Nonswellable Polytetrafluoroethylene/Poly(acrylic acid-co-hydroxyethyl methacrylate) Composite Fiber and Its Stable Catalytic Activity for Methylene Blue Oxidative Decolorization

“…Fe 2p3/2 peak can be deconvoluted into four components, which are located at 705.1, 709.5, 712.5, and 715.9 eV, as shown in Figure 9. These components correspond to metallic Fe, Fe 2+ , Fe 3+ , and satellite peak [25,26]. The table in Figure 9 describes the relative content of metallic Fe, Fe 2+ , and Fe 3+ , which is calculated based on the area of the deconvoluted peaks.…”

Bandgap tuning of photo Fenton-like Fe3O4/C catalyst through oxygen vacancies for advanced visible light photocatalysis

“…The characteristic peak at around 719.0 eV for Fe 3+ in γ-Fe 2 O 3 phase isn't observed, authenticating the formation of pure Fe 3 O 467 . The deconvolution of O 1s XPS curves in Figure4creveals that the O 1s peak is splitted into two peaks for M 1 , the most intense peak at 530.2 eV results from the lattice oxygen in Fe 3 O 468 while the other peak at 531.6 eV having shoulder resulting from the saturating surface oxygen vacancies on atmospheric exposure29,30,69 . Conversely for M 2 the O 1s spectra (Figure4d) are deconvoluted into two peaks, a negative binding shift of 1.6 eV was observed and the corresponding binding energies for Fe-O and O-H was 528.6 and 530.0 eV, respectively30 .Materials Advances Accepted ManuscriptOpenAccess Article.…”
