Physico-Chemical Study on the Mechanism of Interaction Between Divalent and Trivalent Iron Double Oxide Nanoparticles With Fibrillar Protein-Gelatin

The study investigates the interaction mechanism between ferrum(II, III) oxide (Fe₃O₄) nanoparticles and the fibrillar protein gelatin (Gel) using a set of physicochemical methods. For the first time, it was established that the formation of a stable intermolecular complex is due to the amphiphilic and clusterophilic properties of Fe₃O₄ nanoparticles, their ability to polarize, electrostatic interactions, and the formation of supramolecular structures.

The Study of the Interaction Mechanism of Linoleic Acid and 1-Linoleyl-2-Oleoyl-3-Linolenoyl-Glycerol with Fe3O4 Nanoparticles

The interaction mechanism of Fe3O4 nanoparticles with linoleic acid and 1-linoleyl-2-oleoyl-3-linolenoyl-glycerol represented by two-layer coordination model has been determined. By means of Fourier spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray phase and thermal gravitational analysis, the interaction mechanism of lipids (linoleic acid and sunflower oil) with Fe3O4 nanoparticles has been studied.

Mechanism and Mathematical Model of Н2S Chemisorption on Modified Bentonite

New H2S adsorbent was synthesized on the basis of bentonite. It was analyzed using elemental and BET surface area analysis. Models and mathematical representations of mechanisms that govern the chemisorption of hydrogen sulfide on the chemically treated bentonite were presented. The models adequacy was assessed by means of statistic t-criterion.
