The Effect of Ultrasonic Treatment on the Physical–Chemical Properties of the ZnO/MoO3 Systemface area of the compositions take place. The samples obtained after UST demonstrate very promising results in the oxidative dehydrogenation of ethanol to acetaldehyde and the treated composition with a ratio of Zn/Mo?=?50:50 permits an acetaldehyde yield equal to 94% to be obtained at a reaction temperature of 255?°C.

The Effect of Mechanochemical and Ultrasonic Treatments on the Properties of Composition CeO2–MoO3?=stics of hydrogen temperature-programmed reduction (H.-TPR). The results of the catalytic activity of activated samples in an ethanol oxidation reaction demonstrate the high yield of acetic aldehyde (95%) at 230?°C and the productivity of this product (0.9?mol/kg. · h).

Nanoscale Investigation of Porous Structure in Adsorption-Desorption Cycles in the MgO-Al2O3 Ceramicnanopore sizes and to study the processes occurring in them. It was established that the nanopores fraction with a radius of ~1.5?nm is an order of magnitude higher than the proportion of pores with a radius of ~ 0.3?nm, in which also the ortho-positronium annihilation in adsorbed water occurs.

Development of a Controlled in Situ Process for the Formation of Porous Anodic Alumina and Al Nanomecurve was applied. The obtained Al nanomesh was studied by the SEM method. Particular attention is paid to the connection between the features of the initial thin-film structures and the formed Al nanomesh.

Metal Surface Engineering Based on Formation of Nanoscaled Phase Protective Layers influence of the metal potential and pH on the mechanism of action and the efficiency of the individual additives and their compositions has been determined. It was shown that the most dense nanoscale phase layers that ensure highest protective efficiency may be formed using synergistic mixtures of inhibitors with different mechanisms of action.

IV–VIB Group Metal Boride and Carbide Nanopowder Corrosion Resistance in Nickeling Electrolytesund that, by the corrosion resistance in the electrolytes solutions, nanopowders of borides and carbides within each group of compounds are similar and characterized by unlimited period of induction in alkaline media. An exception is the nanopowder of silicon carbide which is resistant to the solution of any acidity.
