New technical solutions in nanotechnology. Part 1

The new technical solutions including inventions in the area of nanotechnology and nanomaterials are efficiently applied in communal and housing services as well as in construction and other joint fields. The invention «The method to purify surface and underground water from titanium and compounds of it by means of carbon nanotubes and ultrasound (RU 2575029)» refers to absorptive treatment of surface and underground waters with rich content of titanium and its compounds and can be used to obtain safe drinking water. This method includes the contact between polluted water and adsorbent. Carbon nanotubes used as adsorbent are placed into ultrasound bath and then carbon nanotubes with purified water are treated for 1–15 min with frequency 42 kHz and power 50 Watt. The technical result is the 100% purification of the water from titanium and its compounds due to high adsorption parameters of carbon nanotubes. The specialists may be also interested in the following inventions: the method to produce of carbon nanotubes with controlled surface den sity (RU 2569548), sheet flaky polymer wear-resistant composite material (RU 2576302), automated technological line for surface modification with metaloxide nanoparticles of polymer fibrous material (RU 2542303), the method to produce nanosize powder of yttrium aluminum garnet (RU 2576271), the method to produce foam polyurethane nanocomposite (RU 2566149), the method to produce crystal diamond particles (RU 2576055), the method to produce nanoporous polymer materials (RU 2576049), nanoporous polymer foam with high porosity (RU 2561267), the method to produce ceramic composite material based on aluminium and zirconium oxides (RU 2549945), catalytic composition for carbon nanotubes synthesis (RU 2575935), the method to produce functionalized graphene and functionalized graphene (RU 2576298) et al.
