Extended Abstract: <\/strong>The invention \u00abThe method of production of carbon nanomaterial (RU 2509053)\u00bb can be used as an additive for concretes and polymers which significantly improves their performance characteristics. The method of production of carbon nanomaterial consists of the following stages: preliminary preparation of sphagnous moss when it is refined from foreign admixtures, dried up to 10% humidity and ground, then ground material is exposed to pyrolysis under the temperature 850\u2013950\u043eC for 1\u20132 hours and cooled up to the environment temperature. After that amorphous carbon obtained in pyrolysis is treated with mechanical activation in the variable planetary mill for 7\u201310 hours. The invention makes it possible to provide increased outcome of nanotubes with high cleanliness.<\/p>\n

The invention \u00abThe method of production of nanodispersed metal powders and alloys of them (RU 2509626)\u00bb relates to the powder metallurgy. Powder metal chloride or powder mixture at least of two metal chlorides is treated in the environment of the water steam which is supplied in reaction space at the rate of 50\u2013100 ml\/min at the temperature 400\u2013800\u043eC at the presence of absorbent carbon or introducing carbon oxide (II) obtained during dissolution of formic acid HCOOH. The invention provides reliable production of nanodispersed metal powders and alloys of them from 3-d metal range: Ni, Co, Cu, Fe, Zn which can be used in powder metallurgy to improve baking process, in chemical industry as the fillers of polymers and reaction catalysts; as additives to anticorrosive covers, etc.<\/p>\n
