The study results of the zinc coating obtained on the surface of metals in the process of mechanochemical synthesis, implemented in the conditions of vibrowave systems, are presented. The features of coating formation mechanism, an activating role in its formation of free-moving, under the influence of low-frequency vibrations, indenters, are disclosed. The advantages of applying zinc coatings method in comparison with traditional methods are shown.

Studies were carried out to combine vibration processing and oxidation in polymer working media, which allowed to combine three technological stages. Characteristic traces of direct and oblique impact of the polymer working medium, along the surface of the metal with oxide film, are determined. Studies of the structure of the nanorelief of the vibrational chemical-mechanical oxide coating and the main parameters of the process are.

The key aspects and specificity of “green” marketing in comparison with the traditional marketing concept along with the areas of environmental activity of agricultural organizations and farms are discussed in the article. The results of the study conducted with the participation of marketing departments’ representatives of agricultural organizations of the Southern Federal District are presented in the paper. The research made it possible to identify the main challenges for organic agriculture development and use of “green” marketing tools in the activities of agricultural enterprises. Based on the discussion of the study results as well as on the analysis of scientific literature on the development of “green” marketing and organic agriculture, the directions of Russian agricultural organizations’ activity are suggested, which can contribute to the use of “green” marketing tools and improvement of business environmental friendliness, taking into account current global trends of sustainable development and corporate social responsibility.

“Smart City” is a key urban trend of our time. The principle of applying the “smart city” model in modern socio-economic systems management in the form of cities, districts, regions and even countries is based on the fact that the urban space is equipped with a digitalization function to increase the urban space comfort for the residents and the guests of this territory. In Russia, this concept introduction founder for objective reasons - the territory size, cargo and passenger flows, a huge tourist and recreational cluster – has become the capital - the city of Moscow [1]. At present, at the state level, the question about the need to develop and implement projects in the “smart city” sphere in small cities, and especially in single-industry towns [2, 3], in the view of solving the able-bodied population outflow key problem from the cities of this type has been raised.
