AbstractMultilayer graphene has been obtained by ultrasonic splitting of graphite microparticles in a surface-active solvent that is a mixture of nonane and water and a surface-active surfactant, which provides dispersion of graphene in hydrophilic systems, has been selected. The chemical structure of the obtained materials has been investigated by IR Fourier spectroscopy. Possible mechanisms of the influence of inorganic surfactants (sodium liquid glass) on the graphene, the type of relations that arise between it and the graphene surface, and possible areas of its application have been discussed.

Possibility to prepare finely dispersed Cu2ZnSnS4 by using the method of self-propagating high-temperature synthesis has been studied in this work. Investigations of Raman scattering and IR-Fourier spectroscopy of the synthesized finely dispersed material have been carried out. The analysis of the Raman and IR-Fourier spectra showed that the synthesized material in the process of preparing is formed with a kesterite structure with the inclusion of a certain amount of secondary phases in the form of sulfides and stannites.

The 1:1 molecular complex of licorice triterpene glycoside glycyrrhizic acid (in the form of monoammonium salt) with cholesterol was obtained in 80% aqueous isopropyl alcohol for the first time. The complexation was studied by 13C NMR, UV, and ATR IR-Fourier spectroscopy. The hydrogen bonds and hydrophobic interactions are formed in the molecular complex.

The goal of the present research is to study the hemocompatibility of magnetic nanoparticles (MNPs)  in model systems in vitro.Materials and methods. Magnetite nanoparticles and magnetite colloidal solutions were used in 0.9% NaCl in concentrations 0.2, 2.0 and 20.0 mg/ml. The study was performed with heparinized human whole blood, 1 ml of which was mixed with 1 of ml nanoparticles/physiological solution. Measurements were made directly after mixing, and then 1, 2.5 and 5 hours later. The amount of reactive oxygen species (ROS) was measured with luminol-dependent chemiluminiscence (CL). An erythrocyte aggregation index was calculated. For the assessment of hemolytic properties, a hemolysis coefficient was calculated based on optical density of the plasma. The nanoparticless surface protein layer investigation was performed with IR-Fourier spectroscopy.Results. Nanoparticles decline CL in timeand concentration-dependent manner. Erythrocyte aggregation stability grows, but concentration and/or application time increment leads to significant hemolysis. IR-Fourier spectroscopy data shows albumin as main component of protein crown, whose conformation changes in time.Given data proves safety of studied MNPs in relation to examined parameters in low (0.2 and 2.0 mg/ml) concentrations up to 2.5 hours interaction. This allows us to treat these MNPs as a promising agents for further use in medical practice after completing examinations related to other homeostasis indicators.
