“…Firstly, S1 is the composite of NiFe 2 O 4 + fcc Fe-Ni + bcc Fe-Ni. Since the magneto-crystalline anisotropy constant ( K 1 ) of cubic NiFe 2 O 4 (~10 5 J·m 3 ) is larger than that of either fcc or bcc Fe-Ni alloys (~10 3 J·m −3 )414243, the exchange interactions between the NiFe 2 O 4 and Fe-Ni NPs contribute to the largest H c value (364 Oe) of S1 among the four samples. Secondly, both of our prepared Fe-Ni alloy nanoribbons (S2 and S3) and nanochains (S4) are self-assembled by Fe-Ni NPs.…”

Iron-nickel (Fe-Ni) alloy nanoribbons were reported for the first time by deoxidizing NiFe2O4 nanoribbons, which were synthesized through a handy route of electrospinning followed by air-annealing at 450 °C, in hydrogen (H2) at different temperatures. It was demonstrated that the phase configurations, microstructures and magnetic properties of the as-deoxidized samples closely depended upon the deoxidization temperature. The spinel NiFe2O4 ferrite of the precursor nanoribbons were firstly deoxidized into the body-centered cubic (bcc) Fe-Ni alloy and then transformed into the face-centered cubic (fcc) Fe-Ni alloy of the deoxidized samples with the temperature increasing. When the deoxidization temperature was in the range of 300 ~ 500 °C, although each sample possessed its respective morphology feature, all of them completely reserved the ribbon-like structures. When it was further increased to 600 °C, the nanoribbons were evolved completely into the fcc Fe-Ni alloy nanochains. Additionally, all samples exhibited typical ferromagnetism. The saturation magnetization (Ms) firstly increased, then decreased, and finally increased with increasing the deoxidization temperature, while the coercivity (Hc) decreased monotonously firstly and then basically stayed unchanged. The largest Ms (~145.7 emu·g−1) and the moderate Hc (~132 Oe) were obtained for the Fe-Ni alloy nanoribbons with a mixed configuration of bcc and fcc phases.

“…For instance, Zn-Mn-Co-ferrites consists of iron oxide and one or more other cations of these transition metals. Magnetic ferrite is widely valued in different fields due to its high electrical resistance, excellent magnetic properties, chemical stability, mechanical rigidity, and relatively low cost; these materials' properties vary significantly from the properties of bulk materials [67][68][69][70]. As illustrated in Table 1, the recycling and recovery of ferrites NPs from the spent wastes started in the last decade, approximately in 2004.…”

The exploitation of spent battery and electronic waste for the recovery and preparation of metal oxide nanomaterials (MONMs) is vital for technology, economical, sustainable, and environmental research. The recovery of MONMs through recycling waste materials reduces environmental pollutions and saves the primary resources due to industrial consumption. However, the economic benefits of recycling electronic waste for the recovery of these high-value MONMs have still been debated because of the low purity and stability of recovered materials restricting their commercial use. In this chapter, we discuss the motivation and importance of waste recycling for the recovery of nanomaterials, focusing on the possible techniques that can be applied for the efficient synthesis of commercial-grade MONMs (e.g., ferrites, zinc oxides, indium oxides, tin oxides, etc.) with high purity at a minimal cost. Besides, the profit of recovered MONMs in potential applications for wastewater remediation and renewable energy production are addressed.

“…The magnetic characteristics of NNFs differ significantly from microparticles [19,20]. On the one hand, nanosized NiFe 2 O 4 has a small magnetization and on the other hand, it has a higher coercive force compared to micro-sized nickel ferrite [21]. Nanoscale nickel ferrite exhibits magnetically soft properties as well as magnetic permeability, high electrochemical stability, and catalytic properties as demonstrated in [22,23].…”

Composite materials based on NiFe2O4 nanoparticles and polyethylene matrix have been synthesized by thermal decomposition to expand the application area of high-pressure polyethylene by filling it with nanoscale particles. The synthesized compositions were obtained in the form of a dark gray powder and compressed for further study According to TEM, the average particle size in composites was 2, 3, and 4 nm in samples with a filling of 10%, 20% and 30%. The concentration dependences of the specific electrical resistivity ρV, dielectric permittivity ε, saturation magnetization MS and the parameters of reflection and attenuation of microwave power of the obtained composites were investigated. The threshold for percolation in such materials is found to be within a concentration range of 20…30%. The electronic and atomic structure of composites was studied by methods of Mössbauer spectroscopy, X-ray diffraction and X-ray absorption spectroscopy. The closest atomic environment of nickel and iron in nanoparticles is close to that of crystalline NiFe2O4. The dependence of the nanoparticles size as well as the dependence of the number of tetrahedral or octahedral iron positions in nickel ferrite nanoparticles to their content in polyethylene matrix is established. It is shown that composite materials based on NiFe2O4 nanoparticles and polyethylene matrix can be used as components of electromagnetic compatibility systems.
