The review of patents in the area of nanotechnologies and nanomaterials.Part 2

The inventions in the area of nanotechnologies and nanomaterials bring a great efficiency to construction, housing and communal services and joint spheres of economy. The invention «The method to produce photocatalytically active nano- crystal titanium dioxide of anatase modification (RU 2551677)» refers to the meth- ods for production of nanocrystal titanium dioxide which can be used to provide air and water photocatalytic treatment and disinfection, to create photoelectric en- ergy converters, new composite and catalytic materials. The technical result of the new method is the reduced time consumption for hydrolysis reaction; formation of crystal structure of anatase directly as an outcome of crystallization from solution under the temperature not exceeding boiling temperature under atmosphere pres- sure without application of additional thermal treatment of the sediment. The in- vention «The method to produce ceramic composite material based on aluminium and zirconium oxide (RU 2549945)» refers to manufacture of ceramic construc- tional and functional materials. The technical result is the production of ceramics with increased crack-resistance coefficient. The specialists may be also interested in the following nanotechnologi- cal inventions: the method to produce mixture for composite cellular concrete (RU 2543847), nanostructured welding wire (RU 2538228), nanofiber polymer material (RU 2543377), the method to produce metal nanopowders with increased stored energy (RU 2535109), the method to produce nonwoven nanocomposite material (RU 2533553), the method to produce nanodispersed nanopowders and the equipment for it (RU 2533580), the method to produce nanostructured coat- ings with shape memory on steel (RU 2535432), the method to apply nanodiamond material with combined electromechanical treatment (RU 2530432), the method to produce soot containing fullerenes and nanotubes from gaseous carbon matter (RU 2531291), polymer copper-containing composite and the method to produce it (RU 2528981), thin dispersed organic suspension of metal/carbon nanocomposite and the method to produce it (RU 2527218), composite ion-exchange membrane (RU 2527236), cutting plate (RU 2528288), the method to produce sensitive ele- ment of gas detectors with carbon nanotubes (RU 2528032) et al.
