The review of patents in the area of nanotechnologies and nanomaterials. Part 3

The inventions in the area of nanotechnologies and nanomaterials produce a profound effect in construction, housing and communal services and adjacent economic fields. The invention «The method to produce body of oriented carbon nanotubes on the surface of base plate (RU 2561616)» refers to the technologies for production of body of carbon nanotubes on the surface of base plate. The flow of actuation gas is formed in the reaction chamber. The flow contains carrying gas, gas hydrocarbon and predecessor of catalyst for synthesis of carbon nanotubes. In some cases, when implementing invention, the flow of inert gas is directed to the surface of the base plate. This gas flow shades the zone of synthesis of carbon nanotubes from air when its pressure exceeds the pressure of actuation gas flow. The method provides the body of oriented carbon nanotubes on the base plates with big surface: up to several square metres. The invention «Composition of mixture for asphaltic concrete (RU 2561435)» refers to the construction production in highway industry and can be applied in manufacture of asphaltic concrete including nanotechnologies. The specialists may be also interested in the following nanotechnological inventions: the method to modify carbon nanomaterials (RU 2548083); nanofi- ber polymer material (RU 2543377); the method to produce nanosuspensions for manufacture of polymer nanocomposite (RU 2500695); the method to strengthen metal products to obtain nanostructured surface layers (RU 2527511); the method to form heat-resistant nanocomposite coating on the surface of the products made of heat-resistant nickel alloys (RU 2549813); the method to apply nanodiamond material by means of combined electromechanical treatment (RU 2530432); the method to produce soot with content of fullerens and nanotubes made of gas carbon raw material (RU 2531291); the method to produce powders of zinc oxide with surface modification for usage in construction sealing materials (RU 2505379); high resource electric arc generator of low-temperature plasma with protective nanostructured carbon coatings of electrodes (RU 2541349); the method to produce laminated nanomaterial (RU 2530456); fine-dispersed organic suspension of metal/carbon nanocomposite and the method to produce it (RU 2527218); the method to produce metal nanopowders with increased stored energy (RU 2535109) et al.
