We are witnessing global climate change on Earth. All this happens due to 
an increase in the CO
2
gas in the atmosphere. This gas is formed mainly as a result 
of the burning of natural energy resources, such as natural gas, oil and coal. To 
solve this problem, it is necessary to expand the scope of development of energy-
saving technologies and at the same time pay special attention to the development 
of new trends in nanotechnology. 
In recent years, nanotechnology has practically stood out as an independent 
scientific field, which gives a new impetus to the development of many industries 
related to materials science - precision machine and instrument engineering, the 
creation of new chemical materials using highly efficient and precision methods, 
etc. 
Obtaining highly pure substances with impurities of less than 10
-8
% is 
possible using a multi-column adsorption system for cleaning chemical 
components. The number of columns varies from 500 to 10,000 in the purification 
system. To create highly pure substances in large quantities, an adsorption system 
with a column number of at least 5000 pieces should be used. 
Further focusing on the practical use of highly pure substances, it can be 
noted that, in terms of volume of use among highly pure substances, primacy 
belongs to such materials as silicon, germanium and gallium arsenide. These 
substances in especially pure form are mainly used in the production of digital 
microcircuits, transistors, microprocessors of increased accuracy and speed. And 
also in the manufacture of ultra-high power LEDs. 
Second place in the palm of the use of highly pure substances is carbon. On 
the basis of highly pure carbon, carbon nanotubes having extraordinary strength 
characteristics can be grown. Along with this, it should be noted that it has 
increased heat resistance. Without carbon nanotubes, it is impossible to imagine 
the further development of space and aviation technology. In addition, highly pure 
carbon is widely used in the cultivation of high-quality artificial diamond and 
diamond blades. It is predicted that in the near future, diamond wafers will 
supplant silicon and germanium in the production of microelectronics.
