This paper describes the smart city definitions and expresses a view that smart city infrastructure consists of digital technologies and information and communication technologies. We make the point that the terms Urban Digitality, Urban Computing and Urban Informatics are used to describe smart city’s underlying digital technologies in English language scientific literature. The three-step American smart city model is analyzed. The model supposes a city to collect information about itself using sensors and other devices on the first stage. On the second stage collected data is transferred by means of wired and wireless networks to be analyzed on the third stage for better understanding of the present situation and what may happen in the future. Having found that the digital technologies of internet of things, social networks and mobility correspond to the stage of «Collect», so as the technology of cloud computing is brought into correlation with the stage of «Communicate» and, finally, that the digital technologies of big data and analytics are compared to the stage of «Crunch», we reveal the substance of smart city technological base.

Smart cities development initiatives, which become the response on growing urbanization, rise the problem of smart city digital technologies study. Digital revolution grows stronger, so it makes possible to use digital information and communication technologies in city management and allows rise of life quality. The digital revolution modern stage is characterized by the technologies combination of the third digital platform which is briefly referred to as SMAC, on the first English letters of social networks, mobility, analytics and cloud computing. This paper describes IBM’s smart city model, which consists of three stages: instrumentation, interconnection and intelligence. Instrumentation means that the workings of the system are turned into data points and the system is made measurable. Interconnection means that different parts of a core system can interact with each other, turning data into information. Intelligence refers to the ability to use the created information in decision making processes. We declare that the third digital platform technologies having been correlated with the model stages could be considered as the digital technologies of a smart city.

It is noted that traditional technologies do not provide removal of organic substances from water, and primary chlorination leads to the formation of highly toxic halogen organic compounds in it. The perspective of using membrane technologies for water purification of surface sources based on: micro-, ultra- and nanofiltration, reverse osmosis, allowing to solve the set task is shown. This was realized during the purification of the Don and Moscow rivers with the use of the biosorption-membrane method, which involves sorption on activated charcoal, biological oxidation of organic substances and filtration through the membrane. The obtained results give the basis for wide application of this method in treatment plants of small settlements, which is especially important for the south of the country, in particular, the Rostov region and the Republic of Kalmykia.

Many complex oxides of transition metals show effect of enormous dielectric permeability. New complex layered oxides LnSr2CuTiO6,5 (Ln = La, Nd, Pr) are synthesized. Their structure by means of x-ray diffraction on the Shimadzu XRD-7000 S is investigated. Processing of XRD was carried out in the program FULLPROF-2013. The main X-ray reflexes are indicated in space group I4/mmm (№ 139). The data of the crystal-chemical analysis which are carried out taking into account a charge state and coordination environment of cations show that distortion of coordination polyhedrons is significantly reduced in series Ln = La→Nd. The unit cell parameters naturally decrease according to reduction of ionic radiuses of La→Nd. Dielectric properties of materials investigated using the universal analyzer of a frequency response Solartron 1260A in the range of frequencies 1mHz - 16МHz with a signal amplitude 500-900 mV. Increasing the dielectric constant is possible due to the charge ordering caused by uneven distribution of charge. Frequency dependences of an imaginary and real part of dielectric constant are given.
