“…Nanomaterials can be found in fused, single and aggregated procedures with irregular, tubular and spherical forms. The mostly commonly used nanomaterials consist of dendrimers, nanotubes, fullerenes and quantum dots [1,2]. In recent years, the nano ferrites spinel compounds have been investigated for their uses in technology fields for example high density information storage, drug delivery, magnetic chips and ferro fluids etc.…”

“…As we can see from Figure 1(a), the XRD spectra of pure PANI have two distinct sharp peaks at 2θ °equal to 19.4 °and 26.3 °with planes of (010) and (200) [19]. For PANI doped by ZnFe 2 O 4 nR, there are peaks at 2θ °equal to 30 °, 37 °, 43 °, 57 °, and 65 °with planes of (220), (311), (400), (440), and (551), respectively [20,21]. Te exited sharp peaks in the XRD pattern after the doping of ZnFe 2 O 4 nRs assured the crystallinity of the composites which will afect the light propagation and decrease the scattering.…”

The wide-ranging potential of polyaniline (PANI) composites in energy storage, electrochemical, sensing, and electromagnetic shielding applications emphasizes researchers to improve its properties. Here, the doping of ZnFe2O4 nRs by 1, 3, and 5 wt. % within polyaniline has been done. Then, we characterize the doped material using techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), and Fourier-transform infrared spectroscopy (FTIR) to verify the successful incorporation of polyaniline onto the nRs. TGA showed that doping of PANI with ZnFe2O4 nRs enhanced the interfacial interactions between the two components. This provided a more stable matrix structure and enhanced the thermal stability of the composite. The transmission of light has been increased by about 18% due to the increase in crystallinity accompanied by ZnFe2O4 doping. As the ZnFe2O4 nRs doping rose, our PANI samples’ optical band gap values slightly decreased by about 10%. In addition, it has been found that the optical characteristics such as refractive index, extension coefficient, surface, and volume energy loss function essentially showed ZnFe2O4 doping dependency. The nonlinear constants of the doped samples have increased due to the new charge carriers and altered the electronic and optical properties of the composite material. Our obtained results show that PANI@ ZnFe2O4 nRs have potential applications such as optical sensors, electrochemical, optoelectronics, and photocatalysis.

“…Nowadays, nanocrystalline materials have become a very vital and active research subject owing to their rapidly developing in manufacturing sectors and spreading to almost every field of science from engineering to medical [1]. Spinel ferrites (MFe 2 O 4 ; M = Ni, Co, and Mn) represent a significant class of magnetic materials however their uses for biomedical applications are disadvantaged because of the high inherent poisonousness of these metals [2].…”

Graphene oxide (GO) nanostructures are systems with many fascinating novel properties that can be used to study new science and have significant promise for applications. In this study, graphene oxide was prepared using the modified Hummer’s method. In addition, potassium ferrite is a good candidate for biomedical application, as iron and potassium are biocompatible and non-toxic materials. Mg0.85K0.3Fe2O4/GO nanocomposites were prepared by the citrate auto-combustion method. The effect of adding GO to Mg0.85K0.3Fe2O4 on structure, morphology, electrical, and magnetic properties was discussed. Samples under investigation were characterized using XRD, infrared spectroscopy (IR), high-resolution transmission electron microscopy (HRTEM), and atomic force microscopy (AFM). The crystallite size of prepared samples was decreased from 28.098 to18.148 nm by increasing GO content. Scanning electron microscope (SEM) confirms the successful adhesion of Mg0.85K0.3Fe2O4 nanoparticles on graphene oxide sheets, which are dispersed in a metal oxide matrix. EDAX analysis confirms the existence of C, O, K, Mg, and Fe elements present in the samples. Magnetic properties were studied by VSM and Faraday's method. GO has a significant effect on the magnetic properties of nanocomposites. For instance, the saturation magnetization and Curie temperature have diverse values, which will be appropriate for numerous applications.
