“…After 30 min, a suspension of dark brown color was obtained and placed in the oven at 160 • C for 20 h. The acquired precipitate was washed and dried at 60 • C for 2 h. TEM image of ZnFe 2 O 4 @CMC as a prepared photocatalyst for degradation of CIP is shown in Figure 9c. The photocatalytic activity of ZnFe 2 O 4 @CMC was evaluated by studying the effect of reaction time (20-120 min), the initial concentration of CIP (5-30 mg/L), pH (3)(4)(5)(6)(7)(8)(9)(10)(11), the dose of photocatalyst (0.1-0.5 g). The optimal conditions for maximum removal efficiency in synthetic (87%) and natural (79%) samples were: pH = 7, initial CIP concentration-5 mg/L, photocatalyst dose-0.3 g and irradiation time-100 min.…”

“…Magnetic force microscopy (MFM) is a scatter-sensitive technique with a resolution of up to 10 nm that can detect weak magnetic fields. MFM is a universal method of analysis of magnetic nanoparticles due to the simple requirements for sample preparation, the ability to work in air, vacuum or liquid medium [8]. Due to this, MFM is a powerful tool for imaging of magnetic NPs, characterizing their size and morphology.…”

Increased request for metal and metal oxide nanoparticles nanoparticles has led to their large-scale production using high-energy methods with various toxic solvents. This cause environmental contamination, thus eco-friendly “green” synthesis methods has become necessary. An alternative way to synthesize metal nanoparticles includes using bioresources, such as plants and plant products, bacteria, fungi, yeast, algae, etc. “Green” synthesis has low toxicity, is safe for human health and environment compared to other methods, meaning it is the best approach for obtaining metal and metal oxide nanoparticles. This review reveals 12 principles of “green” chemistry and examples of biological components suitable for “green” synthesis, as well as modern scientific research of eco-friendly synthesis methods of magnetic and metal nanoparticles. Particularly, using extracts of green tea, fruits, roots, leaves, etc., to obtain Fe3O4 NPs. The various precursors as egg white (albumen), leaf and fruit extracts, etc., can be used for the „green” synthesis of spinel magnetic NPs. “Green” nanoparticles are being widely used as antimicrobials, photocatalysts and adsorbents. “Green” magnetic nanoparticles demonstrate low toxicity and high biocompatibility, which allows for their biomedical application, especially for targeted drug delivery, contrast imaging and magnetic hyperthermia applications. The synthesis of silver, gold, platinum and palladium nanoparticles using extracts from fungi, red algae, fruits, etc., has been described.

This article presents the results of a study on the dynamics of a volume of magnetic fluid levitating in a uniform magnetic field of an electromagnet experiencing an oscillatory shift. Samples with different physical parameters were considered, and the dependence of the magnetoviscous effect was studied. It showed that the greatest influence on the dynamics of a magnetic fluid that experiences vibrational-shear and magnetic-viscosity effects is exerted by the sample microstructure and the presence of large magnetic particles. The results of this work can be used in the development of a technique for magnetic fluid samples express testing, as well as in the development of acceleration and vibration sensors based on magnetic fluids
