Zn‐Cr‐co‐substituted Cu1‐xZnxFe2‐2xCr2xO4 ferrites (where x = 0.0–0.5) were prepared via thermal decomposition of oxalate precursors. The thermal decomposition up to ferrites formation was followed by differential thermal analysis–thermogravimetry measurements. Mössbauer technique was used to predict the possible cation distribution of the entire system, and X‐ray diffraction, Fourier transform infrared, and electromagnetic measurements were used for confirmation. The superparamagnetic characteristics estimated via Mössbauer studies, for samples with higher substitution, agreed well with vibrating sample magnetometer, magnetic susceptibility, and conductivity results. All the samples showed semiconducting properties in which conductivity decreases by increasing substitution. The effect of cationic substitution on the entire system was investigated and discussed.

“…22 , and Ni 2+ have been combined with egg white to obtain novel nanomaterials with interesting properties. [23][24][25][26][27][28] However, to date, it appears that the use of egg white as a template for the synthesis of noble metal nanoparticles has not been investigated, let alone these nanoparticles' application in cancer therapy. In the current paper, we report a simple, nontoxic, and eco-friendly green pathway to prepare stable spherical and spheroidal Ag-protein bio-conjugates by using egg white as a stabilizer and reductant.…”

A simple, cost-effective, and environmentally friendly approach to the aqueous-phase synthesis of silver (Ag) nanoparticles was demonstrated using silver nitrate (AgNO 3 ) and freshly extracted egg white. The bio-conjugates were characterized by UV-visible spectroscopy, transmission electron microscopy, Fourier transform infrared spectrometry, and dynamic light scattering. These results indicated that biomolecule-coated Ag nanoparticles are predominantly spherical in shape with an average size of 20 nm. The proteins of egg white, which have different functional groups, played important roles in reducing Ag + and maintaining product attributes such as stability and dispersity. In vitro cytotoxicity assays showed that these Ag-protein bio-conjugates showed good biocompatibility with mouse fibroblast cell lines 3T3. Furthermore, X-ray irradiation tests on 231 tumor cells suggested that the biocompatible Ag-protein bio-conjugates enhanced the efficacy of irradiation, and thus may be promising candidates for use during cancer radiation therapy.

“…In order to enhance the specific surface area, interfacial contact between the reactants and material is expedited, mainly in view of catalysis. Spinel crystal ferrites belong to a class of ceramic materials that are of multidisciplinary interest and among the most stable inorganic compounds [20,21]. Owing to compositional diversity, ferrites can serve as core material for electrical [22], magnetic [23,24], catalytic [25], medical [26], water splitting [27,28] and sensing applications [29].…”

Magnetic micro scavengers: highly porous Ni_1−xCo_xFe₂O₄ microcubes for efficient disintegration of nitrophenol

The fabrication of functional materials in patterned morphology is focused to obtain remarkable physiognomies of the materials for certain applications. Instead of randomly distributed agglomerated nanoparticles, it is highly desirable to arrange them in a motif, as this directed formation of nanomaterials can have a substantial influence on their performance and activity in various applications. With this perspective, MOF derived hollow cubes of nickel cobalt ferrites have been synthesized via a facile process using sacrificial templates at 600 °C. Microcubes, composed of tiny grains in a size range from 10 nm ± 2 nm were obtained in pure form as a polycrystalline material. The high specific surface area (1185 m g) and mesoporous nature of hollow cubic ferrites were found to be excellent adsorbents for nitrophenol at room temperature. The equilibrium quantity of adsorbed nitrophenol was calculated as 47 mg g ferrite, accomplished in 7 min. Their large surface area, mesopores and hollow nature, in combination with controlled size distribution of grains, have enabled this remarkable utilization of nanoferrites for removal of nitrophenol from water.
