Extended Abstract: The review gives brief description of inventions in nanotechnological area:

the production method for silver nanoparticles with modified ligand shell in highviscosity matrix (RU 2526967); structures containing molecular structures with high aspect ratio and the production methods for them (RU 2526969); preconcentrator of the samples (RU 2526972); antifrictional composition (RU 2526989); conglutination composition for metal articles (RU 2526991); thin dispersed organic suspension of metal/carbon nanocomposite and the production method for it (RU 2527218); composite ion-exchange membrane (RU 2527236); pigment based on modified titanium dioxide powder (RU 2527262); the method of production of microballs and microspheres (RU 2527427); the method for strengthening metal products with nanostructured surface layers (RU 2527511); the method of production of sensitive element of gas detector with carbon nanotubes (RU 2528032); cutting plate (RU 2528288) etc. The inventions in the nanotechnological area can cause significant effects on construction, housing and communal services and adjacent fields of economy: reduced hardening time and increased durability of adhesive joints, increased wear-resistance of cutting plates, increased strength of materials under compressive forces, descreased detail tearing, etc.

For example, composition for glueing metal products (RU 2526991) contains anaerobic mastic AH-111 and the filler – carbon nanotubes «Taunit-M». The invention shortens hardening time and increases the durability of adhesive joints. Cutting plate (RU 2528288) contains the base made of hard alloy and sprayed on it wear-resistant layer of nanostructured tungsten carbide and nanostructured niobium carbide which grain size is 20–50 nm, and their ratio, mass.%: nanostructured tungsten carbide 90, nanostructured niobium carbide – the rest. That increases wear-resistance of cutting plates, especially in hard cutting modes.

 

Key words: nanotechnologies, nanomaterials, nanocomposites, nanocomposites, nanostructures, nanotubes.
