“…Physical methods of vacuum thermal sputtering seem to be the most suitable for model physicochemical studies due to the high purity of the resulting zinc films. In addition, varying vacuum thermal sputtering mode makes it possible to obtain metal coatings with controlled thickness, ordered structure, and unique functional properties [27,29,30].…”

The adsorption of vinyltrimethoxysilane (VS) on the surface of sputtered (by thermal spraying in vacuum) zinc has been investigated. The adsorption isotherms of VC on zinc from an aqueous solution were obtain. In order to determine the adsorption characteristics of VS molecules and to calculate the heats of adsorption, the obtained adsorption isotherms were mathematically processed in terms of the well-known adsorption approaches (approximations, adsorption isotherms). It has been established that this organosilane was chemisorbed on the surface of freshly deposited zinc after 60 min. After the sample was immersed in the solution, a self-organized organosilicon layer was formed on the metal surface. The application of Fourier transform infrared spectroscopy, atomic-force microscopy, and scanning electron microscopy allowed to us study in detail the interactions between VS molecules and the metal surface and to determine the structural features of the formed surface films. The mechanism of formation of self-assembled surface layers on zinc has been proposed. Electrochemical and corrosion research methods have been used to investigate the anticorrosion characteristics of organosilicon films on zinc. High stability of surface organosilicone layers with respect to the corrosive components of electrolyte action was shown by an infrared spectroscopy study carried out after corrosion tests

“…Such a nanostructure consisting of an active oxide matrix with metal inclusion nanoparticles can be a promising precur sor for growing extended iron oxide nanostructures (hematite whiskers) both in the bulk and on the surface. Herewith, low-temperature annealing allows regulating the size of such whiskers [24].…”

Methods of scanning electron microscopy with an X ray probe, Raman spectroscopy, and ther mogravimetry are used to study the morphology and composition of metal oxide nanocomposites obtained by intense plastic deformation of iron powder and the further annealing in the TGA mode. It is shown that high temperature annealing of activated powder deformation results in the formation of "hematite wood"a layer of "nanoflakes" and "nanoleaves" growing vertically on the composite surface. In addition to its intrinsic functional (sensor, catalytic, semiconductor, adsorption) properties, this structure possesses pro nounced primer properties for further formation of protective surface layers.
