Cubic tungsten carbide WC1−x is distinguished by the difficulty of obtaining in a dispersed and bulk form. The article attempts to plasma dynamic synthesis cubic powder method based on use coaxial magnetoplasma accelerator for generating supersonic jet, which then rapidly cooled. possibility with predominant content (up 95%) shown. Studying influence an arc discharge initiation allowed reveal e...

Excitation spectra of single GaAs/AlxGa12xAs quantum dots ~QD’s! are studied by using a technique of far-infrared single-photon detection. The spectra consist of a single resonance line, the resonance frequency of which is by several percent larger than the cyclotron-resonance frequency but is substantially smaller than the magnetoplasma frequencies of mesa-etched QD’s earlier found through the...

A set of fluid equations, taking into account the spin properties of the electrons and positrons in a magnetoplasma, are derived. The magnetohydrodynamic limit of the pair plasma is investigated. It is shown that the microscopic spin properties of the electrons and positrons can lead to interesting macroscopic and collective effects in strongly magnetized plasmas. In particular, it is found tha...

The possibility of obtaining a dispersed material by the method plasma dynamic synthesis in Ti-O system is shown. based on operation pulsed high-current coaxial magnetoplasma accelerator with titanium electrodes. obtained product was investigated X-ray diffraction and transmission electron microscopy. results showed presence two main oxide (IV) crystalline modifications: anatase tetragonal syng...
