Scientists developed new technology of growing of carbon nanotrubok with the use of diamond nanochastic. Carbon nanotrubki are cylindrical structures by a diameter from one there is to a few ten of nanometrov. The walls of cylinder are built from one layer of atoms of carbon. There are a few technologies of receipt of nanotrubok. In one of most
widespread methods material for the receipt of nanotrubok gas the molecules of which contain a carbon serves as usually. More frequent than all scientists use methane (chemical formula – CH4) of .gaz, heated to the temperatures poryadka 700 degrees celsius, skip through the layer of nanochastic
different metals, for example, of iron, nickel or cobalt. A metal serves as the catalyst of reaction of disintegration of methane on a carbon and hydrogen. Atoms of carbon "settle" on metallic nanochasticy, forming tubes.This method does not allow odnomomentno to get
plenty of nanotrubok. Under act of high temperature of nanochasticy of metals "alloyed" together. In such kind they can not serve as an effective catalyst. If an enough particle is located distant from each other, they do not stick together, however
the number of got nantotrubok diminishes.The authors of new method substituted the particles of metals by diamond nanochasticy by a diameter about five nanometrov, which do not stick together. Methane scientists substituted by an ethanol (at a high temperature he is in a gaseity).
Skipping an ethanol through the layer of diamond nanochastic, researchers got the large number of nanotrubok even in spite of the fact that nanochastcy can not katalizirovat’ the reaction of decomposition of ethanol. A temperature which nanotrubki was synthesized at made 890 degrees
Celcius. At such heating of molecule of ethanol disintegrate "independently".nanotrubki were first got a few decades back. The the last years scientific investigate properties of these objects actively. Nanotrubki potentially able to improve quality
great numbers of devices and to reduce in price some technologies. So, the model of sun batteries was developed on nanotrubkakh, "supermyshcy" from nanotrubok. A report appeared quite recently, that it is possible by nanotrubok "to sew together" materials for airplanes,
