“…6a). Other oxides produced by electrospinning have similar structures when observed by TEM, as described for Nb 2 O 5 [37] and TiO 2 (anatase and brookite) [38] fibers, or NiFe 2 O 4 nanofibers [39]. EDS analysis and electron diffraction measurements are in accordance with the Yb 2 O 3 nature of these nanocrystals.…”

“…The electron patterns obtained from selected area electron diffraction (SAED) show spotty rings, indicating the polycrystalline nature of the material. This feature of polycrystallinity is also found among the oxides mentioned above and studied by TEM (Nb 2 O 5 , TiO 2 or NiFe 2 O 4 ) [38][39][40]. Furthermore, its indexation corresponds well to the Yb 2 O 3 pattern (Fig.…”

“…The FT-IR spectrum of as-spun fiber ( Figure 2 a) shows bands originating from PVP, DMF, nickel nitrate and manganese acetate precursors. OH group vibrations in the 3000–3500 cm −1 range are noted, belonging to residual water in the fibers [ 36 , 37 , 38 ]. The bending vibration of the OH group, usually noted around 1635 cm −1 [ 38 ] is possibly present but masked by the C=O stretching vibration noted at ≈1650 cm −1 of the carbonyl group in PVP [ 39 ].…”

Nickel manganite nanocrystalline fibers were obtained by electrospinning and subsequent calcination at 400 °C. As-spun fibers were characterized by TG/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. X-ray diffraction and FT-IR spectroscopy analysis confirmed the formation of nickel manganite with a cubic spinel structure, while N2 physisorption at 77 K enabled determination of the BET specific surface area as 25.3 m2/g and (BJH) mesopore volume as 21.5 m2/g. The material constant (B) of the nanocrystalline nickel manganite fibers applied by drop-casting on test interdigitated electrodes on alumina substrate, dried at room temperature, was determined as 4379 K in the 20–50 °C temperature range and a temperature sensitivity of −4.95%/K at room temperature (25 °C). The change of impedance with relative humidity was monitored at 25 and 50 °C for a relative humidity (RH) change of 40 to 90% in the 42 Hzπ1 MHz frequency range. At 100 Hz and 25 °C, the sensitivity of 327.36 ± 80.12 kΩ/%RH was determined, showing that nickel manganite obtained by electrospinning has potential as a multifunctional material for combined humidity and temperature sensing.

“…As can be seen in Figure , the crystallite size of the samples rises by increasing temperature. For small particles, the volume fraction ratio of disordering spins due to spin quantic effect of all cations at the surface of nanoparticle is high in comparison with large particles, which, resulting in the lower value of Ms . In addition, distortion of crystal structure due to the decrease in particle size can also reduce the ordering spin of metal ions, leading to depletion of total magnetization .…”

In the present work, Mg 0.5 Ni 0.5 Fe 2 O 4 nanopowders were prepared by a sol-gel combustion method. The magnetic properties, heat generation ability in an AC magnetic field and cytotoxicity of the mixed ferrite nanopowders were investigated. The results showed that the powders have crystalline spinel structure with a particle size in the range of 20-90 nm. Maximum saturation magnetization (Ms) of 51 emu/g was obtained for the Mg 0.5 Ni 0.5 Fe 2 O 4 nanoparticles calcined at 900°C. The results showed that, the coercivity (Hc) of the Mg 0.5 Ni 0.5 Fe 2 O 4 initially increases up to 700°C and then decreases with increasing temperature, whereas the Ms of the samples continuously increases. The Mg 0.5 Ni 0.5 Fe 2 O 4 sample exhibited a temperature increase up to 45°C during 10 minutes in the exposure of magnetic field of 200 Oe. By increasing the viscosity of ferrofluid, the heat generation ability of nanoparticles reduced up to 9% at magnetic field of 200 Oe. Cell compatibility of the ferrite powders was studied by MTT assay using MG63 cell line proliferation. MTT results showed that calcination temperature of the Mg 0.5 Ni 0.5 Fe 2 O 4 nanoparticles significantly affects the cell compatibility.
