Purpose – The purpose of this study is to carry out a comparative analysis of economic results and innovative activity within the scientific and technological clusters of the world, to establish the relationship between the population density of a certain agglomeration and the productivity of its inventors, the effectiveness of researchers and business efficiency, to evaluate the impact of digital technologies on economic success science and technology cluster.

Multi-walled carbon nanotubes and graphite nanoplatelets were functionalized via acid treatment to overcome the problem of agglomeration. Fourier transform infrared spectroscopy showed the chemical modification of the nanocarbons while the general relationship between the chemical treatment and the defects population was analyzed by Raman spectroscopy. The information regarding the mass loss and impurities is obtained from the thermogravimetric analysis. X-ray diffraction showed the effect of acid treatment on the physical states of the nanocarbons including the crystalline texture.

The article is a result of an analytical research on development of relations between the
city and suburban area. An attempt to define main factors that may be included into a future
strategy of balanced development and to avoid a number of problems in the organization of group
forms of settlement in the big cities' influence zone. The decentralization processes in the
governance system constitute the social and economic potential for creation of a system of
common interests in development, and not for destruction of both cities and suburban area.
