| description | Introduction. Advanced technologies impress people’s imagination demonstrating the latest achievements (materials,
methods, systems, technologies, devices etc.) that dramatically change the world. This, first of all, concerns nanotechnological
inventions designed by scientists, engineers and specialists from different countries. Main part. The article provides an abstract
overview of inventions of scientists, engineers and specialists from different countries: Russia, USA, China, Belarus, Italy. The results
of the creative activity of scientists, engineers and specialists, including inventions in the field of nanotechnology and nanomaterials
allow, when introduced to industry, achieving a significant effect in construction, housing and communal services, and related sectors
of the economy. For example, the invention «Protective coating and method of its application» relates to the field of protecting
metals from corrosion. To obtain a protective coating, a composition containing an industrial oil with a powder of a phosphorusmodified
copper-carbon nanocomposite is applied to the surface of an unalloyed steel and subjected to thermochemical activation
by heating for 20 minutes at a temperature of 100–200°C. During the formation of the coating, strong donor-acceptor bonds of
iron atoms with phosphorus, which are in the composition of the copper-carbon nanocomposite, are formed. In the course of
experiments, it was found that heating samples with a coating of oil with the addition of a phosphorus-modified copper-carbon
nanocomposite to 100–200°C increases the chemical activity of the nanocomposite, as a result of which a protective coating forms
on the surface, which reduces the corrosion rate depending on the concentration of the modified metal-carbon nanocomposite.
by 70–95%. The following inventions in the field of nanotechnology are also of interest to specialists: a method for obtaining
a nanostructured surface of a metal workpiece by laser treatment, a device for producing nanodispersed metal oxides, a method
for producing a nanostructured composite material based on aluminum, a method for modifying the surfaces of plates of a brazed
plate heat exchanger, etc. Conclusion. One of the most challenging tasks the economy of every country face is to increase industrial
competitiveness through technological upgrade. From the side of the state and companies the principal object to control in this
process are the people and enterprises dealing with introduction of inventions and new technologies. |
