“…The IFL method is relatively young; however, a large number of NPs have been obtained using it. In refs and , a study was carried out to obtain titanium NPs in an argon flow, and the addition of oxygen made it possible to obtain titanium dioxide . In ref , the flow levitation method was used to synthesize ZnO NPs.…”

Nanoparticles of Al, Mg, Ni, and Ti with an average size less than 50 nm were obtained directly from bulk samples by the inductive flow levitation (IFL) technique. The main advantages of this method are high productivity (up to 200 g/h of nanoparticles), control over the size of nanoparticles in a wide granulometric range (0.5–500 nm), and noncontact heating (up to 2500 °C), which determines the purity of the product and the compliance of the method with the basic principles of “green chemistry” (direct synthesis). The IFL method belongs to gas-phase technologies, a distinctive feature of which is metal evaporation in a suspended state (induction levitation) and noncontact heating. For the levitation of volumetric samples, seven types of induction coils were developed in the work in which the “temperature-levitation” properties were investigated. On the inductor of the fifth type, the modes of obtaining nanoparticles with different masses of the seed and the nature of the purge gas were tested. The resulting nanoparticles were thoroughly characterized by a wide range of physicochemical methods: transmission electron microscopy (TEM), high-resolution TEM, scanning electron microscopy–energy dispersive spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller, STSA, Barrett–Joyner–Halenda, dynamic light scattering, and inductively coupled plasma with mass spectrometry. In this work, it has been shown that the IFL method is one of the most promising methods for the synthesis of nanoparticles today, which allows to obtain NPs with a high degree of purity and homogeneity in one stage.

“…The Guen-Miller flow-levitation method is an alternative approach that allows the synthesizing of core-shell nanoparticles [28], including Fe@C in a high yield [29]. This technique is based on the evaporation of metal from the surface of a melted metal droplet levitating in the high-frequency electromagnetic field of a countercurrent inductor in a vertical reactor.…”

Albumin Stabilized Fe@C Core–Shell Nanoparticles as Candidates for Magnetic Hyperthermia Therapy

Carbon-encapsulated iron nanoparticles (Fe@C) with a mean diameter of 15 nm have been synthesized using evaporation–condensation flow–levitation method by the direct iron-carbon gas-phase reaction at high temperatures. Further, Fe@C were stabilized with bovine serum albumin (BSA) coating, and their electromagnetic properties were evaluated to test their performance in magnetic hyperthermia therapy (MHT) through a specific absorption rate (SAR). Heat generation was observed at different Fe@C concentrations (1, 2.5, and 5 mg/mL) when applied 331 kHz and 60 kA/m of an alternating magnetic field, resulting in SAR values of 437.64, 129.36, and 50.4 W/g for each concentration, respectively. Having such high SAR values at low concentrations, obtained material is ideal for use in MHT.

“…Titanium carbide is one of the most demanded materials widely used in industry, modern engineering and medicine [1][2][3]. The wide range of applications is due to the unique combination of chemical and physical properties of titanium carbide (high wear resistance, corrosion resistance, chemical inertness, high melting point, flexural modulus, etc.)…”

Abstract. The results of research of characteristics of highly dispersed titanium carbide powder obtained from carbide waste of TN-20, TN-25, TN-30 types are presented. The powder particles were studied using analytical methods including scanning microscopy, X-ray diffraction, differential thermal analysis. The obtained results confirm the formation of nanosized particles of titanium carbide of monocrystalline form.
