Experimental installation to study the RF plasma flow at low pressures with experiment data synchronization

The paper describes a technique for the synthesis of microdiamonds, germanium nanoballs and nanotubes in an argon-germanium arc. The evaporation of germanium atoms was carried out from the surface of a graphite rod, which served as the anode of the arc discharge. The synthesis of microdiamonds was observed on graphite substrates near the anode; germanium nanotubes and germanium nanoballs were also found nearby. It has been established that germanium promotes the synthesis of nano and microdiamonds. Synthesized diamonds have a classic structure with rectangle faces and four hexagons adjacent to the edges of this rectangle. The sizes of microdiamonds reach tens of microns. The diameters of germanium nanotubes are of the order of 50-100 nm, and the length is of the order of 10 μm.

In the modern world, polymers are used in almost all areas. Modification of polymer surfaces is an urgent task. Increasing adhesion and wettability is one of the important parameters. There are many different methods for increasing adhesion and wettability. The electrolytic plasma method is one of them. After processing the surface of the polymer by this method, the wettability of the surface of modified polymers with water was studied by measuring the size of a drop of technical water on the surface of the polymer. As a result of experimental studies, the modification of polyethylene terephthalate decreased the wetting angle by 11-24%.

The paper presents the results of an experimental study of the isobaric heat capacity of solutions of electrolytes of the water and NaCl system in the temperature range 288-373K. To measure the heat capacity of electrolytes, the method of monotonous heating was used (developed by Professor M.M.Safarov). The total relative error of measuring the heat capacity of this place with a confidence probability of 95% is on average equal to 3.8%. It is established that the specific isobaric heat capacity of electrolytes decreases with increasing temperature and concentration of sodium chlorine. The addition of fullerene leads to an increase in the heat capacity of solutions of the water and sodium chlorine system. On the basis of experimental data and the law of thermodynamic similarity, approximation dependences were obtained. Using the expressions obtained, it is possible to calculate the heat capacities of electrolytes at different temperatures and concentrations of fullerene nanoparticles.
