“…By increasing milling time up to 18 h, a spontaneous combustion reaction initiated between the NiO and Fe 2 O 3 powder particles to produce Ni-ferrite. It is worth mentioning that the details of phase formation, structural changes of the milled powders of the Ni-ferrite have been reported in our previous published papers [14,15]. Here, we are going to explain a formation of Ni-ferrite by self-propagating high temperature (SHS) through the thermodynamic data.…”

An investigation of the formation of Ni-ferrite from a powder mixture of NiO and Fe 2 O 3 by high-energy ball milling combining X-ray diffraction and differential scanning calorimetry (DSC) is presented. The XRD results indicate that the NiO/Fe 2 O 3 particles reacted in a selfsustaining combustion mode, producing nickel ferrite particles ranging from 5 to 18 nm in size after 18 h of milling. The DSC traces present a broad exothermic reaction peak at the temperature range of 200-1,000°C, with a big mountain-peak around 672°C, of the as-received powder mixture. It shifts from 672 to 647°C by increasing milling time to 18 h. The onset temperature of the transition is in the range of 736-844°C for milled samples between 6 and 18 h. The transition is assigned to the re-crystallization of the nanocrystalline samples. The Curie temperature of Niferrite is also observed in the DSC traces for the 18 hmilled sample, suggesting the Ni-ferrite formation. The performed thermogravimetry for this sample indicates the no mass changes, whereas for as-received powder mixture the mass change is about 1.2 %. FT-IR spectra shows two absorption bands in the Ni-ferrite structure around 400 and 600 cm -1 , which are attributed to octahedral and tetrahedral sites, respectively.

“…However, it also depends on presence of -Fe 2 O 3 phases and their material non magnetic of encapsulating. In addition, the lower amount of magnetization obtained in this study can also related to multiple domains of nanoparticles NiFe 2 O 4 and low shape anisotropy which enables them to magnetize in the direction of easy magnetic axes [20]. is 4.8 ± 0.2 nm became 1.6 ± 0.1 nm and 10.6 ± 0.3 nm after encapsulated PEG-4000 and silica, respectively The TEM results indicate that NiFe 2 O 4 nanoparticles are successfully encapsulated by PEG-4000 and silica.…”

ÖZETNikel demiroksit (NiFe2O4) nanokompozitinin fotoelektrik cihazlar ve sensörlerin yapımı ile modern sanayi alanından manyetik rezonans görüntüleme ve hedeflenmiş ilaç tedavisi gibi biyomedikal uygulamalara kadar hayatımızın pek çok önemli alanında kullanıldığı bilinmektedir. Bu çalışmada, Protective Role of Olueropein Against the Potential Toxicity of NiFe2O4Nanocomposite ABSTRACT Nickel iron oxide (NiFe2O4) nanocomposites are known to be used in many important areas of our lives from photoelectric devices and modern industrial area to magnetic resonance imaging and to biomedical applications like targeted drug therapy. In this study, whether Oleuropein, derived from olive leaves have preventive effect on Drosophila melanogaster wild type strains against the possible toxic effects one of metal oxide nanoparticles, NiFe2O4 (30 nm) were investigated. For this purpose, different concentrations of NiFe2O4 (25, 50, 75,100, 200 and 500 µg/mL) and Oleuropein (100 µM) were used to
