“…In the XRD diffractogram of CuFe 2 O 4 and CuFe 2 O 4 -rGO, peaks at 2θ = 18.16°, 30.11°, 35.62°, 37.36°, 39.01°, 43.27°, 57.46°, and 62.72° referring to (111), (220), (311), (202), (222), (400), (511), and (440) planes of the cubic crystal of CuFe 2 O 4 (JCPDS card no. 77-0010) were observed. ,, This fact highlighted the presence of CuFe 2 O 4 nanoparticles in CuFe 2 O 4 -rGO nanocomposites. Also, the characteristic peaks of GO (i.e., 2θ = 9.76° and 42.14°) are absent in the XRD pattern of CuFe 2 O 4 -rGO, indicating the conversion of GO to rGO during the formation of CuFe 2 O 4 -rGO nanocomposites …”

Energy storage and environmental pollution are two major global concerns in today's scenario. As a result of the momentous exhaustion of fossil fuels, the generation of energy from renewable sources is gaining immense importance. However, the irregular availability of energy from these renewable sources is the major encounter to achieve sustainable energy harvesting technology, yielding efficient but continuous and reliable energy supplies. Apart from the requirement of state-of-the-art heavy-duty technologies such as transportation, defense, etc., in the modern lifestyle to fulfill the demand for flexible electronic devices, the development of high-performance mechanically flexible all-solid-state supercapacitors is increasing massively. On the other hand, to cater to the need for accessibility of clean water for healthy lives, several technologies are evolving to treat wastewater and groundwater. Hence, the development of efficient catalysts for destroying water pollutants is an attractive approach. Considering these two crucial facets, in this paper, we have demonstrated the multifunctional features of a CuFe 2 O 4 -rGO nanocomposite, which was exploited to fabricate a high-performance mechanically flexible all-solid-state asymmetric supercapacitor and simultaneously used as an efficient but easily recoverable catalyst for the transformation of different nitroaromatic compounds. We have also demonstrated the conversion of trifluralin (a herbicide), which is present in the water body as a pollutant, to its corresponding amine derivatives, which can be utilized in the preparation of important pharmaceutical products.

“…It must be highlighted that the thermal performance depends on the concentration of the magnetic NP and also on the composition. It has been reported that Cu doping may enhance the magnetic hyperthermia performance of magnetite [54]; although proving it for our samples is out of the scope of the present work, it should be the focus of a future investigation. From the temperature increase depicted in Figure 6, the specific absorption rate (SAR), which defines the magnetic power absorbed per mass unit of MNPs, can be computed using the expression:…”

The urgency for the availability of new antibacterial/disinfectant agents has become a worldwide priority. At the same time, along with the extensive use of other metal nanoparticles (NPs), the investigation of magnetic NPs (MNPs) in antibacterial studies has turned out to be an increasingly attractive research field. In this context, we present the preparation and characterization of superparamagnetic iron oxide NPs, electrodecorated with antimicrobial copper NPs, able to modulate the release of bioactive species not only by the NP’s stabilizer, but also through the application of a suitable magnetic field. Antimicrobial synergistic CuNPs stabilized by benzalkonium chloride have been used in the current study. We demonstrate the successful preparation of Cu@Fe3O4 MNPs composites through morphological and spectroscopic results. Additionally, an extensive magnetic characterization is reported, along with hyperthermia-induced copper ionic release. On the basis of our results, we propose a new generation of antimicrobial magnetic nanomaterials, whose bioactivity can be also tuned by the application of a magnetic field.

“…The absorption band at wavenumbers 418 cm -1 to 451 cm -1 is caused by the Fe-O strain vibration at the octahedral site [15]. While the absorption band at wavenumbers 680 cm -1 to 696 cm -1 is caused by the dopant strain vibration at the tetrahedral site [9], [16]. The presence of FeO nanoparticles can also be detected where there is an absorption band around the wavenumber of 500 cm -1 [17].…”

The good physical and chemical properties of metal ferrite nanoparticles can be used as potential materials when applied. This study aims to explore the physical and chemical properties, such as phase, structure, morphology, and vibration of Ni-Zn-Co ferrites nanoparticles annealed at different temperatures. Ni0.4Zn0.5Co0.1Fe2O4 nanoparticles were synthesized by coprecipitation method and characterized by X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), and Fourier Transform Infrared (FTIR) Spectroscopy to determine their structure, morphology, and vibration. Overall, all samples showed spinel cubic structures. In addition, XRD analysis showed the phase transformation from magnetite to hematite by increasing the temperature. The increase of annealing temperature leads to the larger average size of nanoparticles which were estimated by analyzing TEM images. The average diameter of nanoparticles with annealing temperature of 600°C was (10.9 + 0.5) nm and the average diameter of nanoparticles with annealing temperature of 1000°C was (18.6 + 4) nm. FTIR measurements between (4000 – 400) cm-1 confirmed the absorption band in the spectrum. The FTIR spectra of the nanoparticles confirmed the presence of metal ion vibrational bands located at octahedral and tetrahedral sites in 418 cm-1 to 696 cm-1. This implies that Ni-Zn-Co ferrites has truly the spinel cubic structures considering their absorption characteristics at about (500 – 600) cm-1.
