“…Magnetite nanoparticles have been intensively investigated for a plethora of technological applications, including MRI, ferrofluids for audio speakers, magnetically targeted drug delivery, magnetic recording media, water purification, oil spill clean‐up, emulsion separation of crude oil, as well as the diagnosis and treatment of bacterial infections. [ 209,210 ] Dissimilatory Fe(III) reduction is the process by which some microbes transfer electrons to external ferric iron [Fe(III)], reducing it to ferrous iron [Fe(II)] without assimilating the iron. [ 211 ] This biologic electron transfer mechanism is utilized by the Gram‐negative metal and sulfur‐reducing bacterium, G. sulfurreducens , in extracellular reduction of Fe(III) iron oxides (Fe 2 O 3 ; rust) to generate soluble Fe 2+ and solid magnetite ( Figure A).…”

Bacteria play an important role in the calcification process of natural minerals and within organisms ( Table 1). It is Microbe-mediated mineralization is ubiquitous in nature, involving bacteria, fungi, viruses, and algae. These mineralization processes comprise calcification, silicification, and iron mineralization. The mechanisms for mineral formation include extracellular and intracellular biomineralization. The mineral precipitating capability of microbes is often harnessed for green synthesis of metal nanoparticles, which are relatively less toxic compared with those synthesized through physical or chemical methods. Microbe-mediated mineralization has important applications ranging from pollutant removal and nonreactive carriers, to other industrial and biomedical applications. Herein, the different types of microbe-mediated biomineralization that occur in nature, their mechanisms, as well as their applications are elucidated to create a backdrop for future research.

“…Iron oxide nanoparticles can be applied in many fields same as in biomedicine as an anticancer and in coating fields as protection against corrosion [1,2]. The properties of iron oxide nanoparticles depend on the size and structure of the particles, and up to now, many researches have been done to improve the magnetic properties of the iron oxide nanoparticles [3][4][5][6][7][8][9]. Due to the attraction between the magnetic nanoparticles, the magnetic nanoparticles have ability to aggregation.…”

In this paper, magnetic nanocomposites were synthesized by embedding ferric oxide nanoparticles into carboxymethyl cellulose (CMC) using coprecipitation method. The properties of the synthesized nanocomposites in the presence of magnetic field were compared to the synthesized nanocomposite in normal condition. The magnetic properties of the nanocomposites were studied by a vibrational sampling magnetometer (VSM) to investigate the effect of the magnetic field on the magnetic properties. The results showed that the presence of magnetic field during the synthesizing, increased the saturation magnetization about 51%. X-ray diffraction (XRD) analysis confirmed the crystallinity of all samples. The SEM images revealed the nanoparticles homogenous dispersing in the composites. Infrared Fourier spectroscopy (FTIR) results confirmed the formation of iron oxide bonds in all samples. The increase of saturation magnetization can be attributed to the magnetic moment alignments by the magnetic field. Magnetic nanocomposites with higher magnetic properties can further develop their application.

The paper presents the results of measurements of electrical strength of Midel 1204 natural ester doped with iron nanopowder in a hydrophobic carbon shell. The research was conducted for different concentrations of the dopant. The samples were prepared in the High Voltage Technique Laboratory. After mixing, they were tightly closed, and the first measurements were taken after 5 weeks of dissolution of the dopant in liquid. The tests were repeated after another 2 weeks and 3 weeks of dissolution of nanoparticles. An increase in both mean and maximum breakdown voltage was shown for the tested liquid mixtures. The concentration for which the value of electrical strength begins to decrease was indicated. It was also shown that a longer time of dissolution of nanoparticles causes an increase in the electric strength value for the tested samples.
