Because of its effectiveness in organic pollutant degradation, manganese peroxidase (MnP) enzyme has attracted significant attention in recent years regarding its use for wastewater treatment. Herein, MnP was extracted from Anthracophyllum discolor fungi and immobilized on the surface of magnetic nanocomposite Fe 3 O 4 /chitosan. The prepared nanocomposite offered a high surface area for MnP immobilization. The influence of several environmental factors like temperature, pH, as well as storage duration on the activity of the extracted enzyme has been studied. Fourier transmission infrared spectroscopy (FT-IR), scanning electron microscope (SEM), X-ray diffraction (XRD), and transmission electron microscope (TEM) techniques were used for the characterization of the prepared MnP/Fe 3 O 4 /chitosan nanocomposite. The efficiencies of the prepared MnP/Fe 3 O 4 /chitosan nanocomposite for the elimination of reactive orange 16 (RO 16) and methylene blue (MB) industrial dyes were determined. According to the results, the immobilization of MnP on Fe 3 O 4 /chitosan nanocomposite increases its capacity to decolorize MB and RO 16. This nanocomposite allowed the removal of 96% ± 2% and 98% ± 2% of MB and RO 16, respectively. The reusability of the synthesized nanocomposite was studied for five successive cycles showing the ability to retain its efficiency even after five cycles. Thus, the prepared MnP/Fe 3 O 4 /chitosan nanocomposite has potential to be a promising material for textile wastewater bioremediation.

“…Heavy metal poisoning will lead to many fatal diseases such as pulmonary edema, kidney failure, cancer. Especially, a high concentration of cadmium (Cd) and copper (Cu) can affect the nervous and skeletal system [1][2][3]. e content of heavy metal ions in drinking water is very low, maximum content of Pb: 0.05 mg/L; Hg: 0.006 mg/L; As: 0.01 mg/L; Cd: 0.003 mg/L; Cr: 0.05 mg/L; Mn: 0.1 mg/L; Cu: 2 mg/L following WHO standard [4].…”

Apatite ore from Lao Cai (Vietnam) has large reserves and low prices. Its main component is fluorapatite. The purification and modification of apatite ore can produce a material that can be used as an absorbent for heavy metals with high efficiency. The molecular structure, phase component, specific surface area, element component, and morphology of modified apatite ore from Lao Cai province, Vietnam, were characterized by IR, XRD, BET, EDX, and SEM methods. The IR and XRD results show that the modified process transformed apatite ore from fluorapatite to nanohydroxyapatite. The specific surface area of modified apatite ore (100.79 m2/g) is much higher than the original ore (3.97 m2/g). The modified apatite ore was used to adsorb Cd2+ and Cu2+ ions in water. The effect of adsorbent mass, pH, contact time, and initial concentration of Cd2+ and Cu2+ on the adsorption efficiency and capacity was investigated. Besides, the isotherm adsorption model was determined using Freundlich and Langmuir theories.

“…Despite the active use of carbon and silicon nanostructures that have proven themselves as anode materials for lithium-ion batteries, due to the high stability and longer service life, there are a number of technological limitations on their production and control of structural properties [10][11][12]. Among the nanostructured materials, Fe-based nanostructures are attractive because of their excellent ferromagnetic properties, high level of magnetization, and ability to control the magnetic texture, which is one of the important characteristics for the potential use of nanostructures in various fields [13][14][15][16][17][18]. However, the possibility of a simple method of obtaining large arrays of nanostructures with controlled geometric and structural characteristics makes iron nanostructures a promising material for the base of lithium-ion batteries.…”

The paper presents the results of the use of iron nanotubes as the anode material of lithiumion batteries. To assess the degradation of the morphology of nanostructures after different numbers of cycles of life tests, the method of scanning electron microscopy, Mossbauer spectroscopy, and X-ray diffraction analysis were applied. It is shown that the decrease in discharge capacity starts at the 380th cycle and is caused by the onset of degradation processes of nanostructures due to the formation of amorphous inclusions and an increase in macrostresses and distortions in the structure. The complete degradation of the structure is observed after the 492nd life cycle test. According to the data obtained by Mossbauer spectroscopy, it has been established that an increase in life cycles leads to an increase in contribution of partial spectrum characteristic of a paramagnetic state. That indicates an increase in degradation rate of nanostructures and an increase in the content of impurity inclusions and amorphous formations in the crystal structure.
