Most state-of-the-art electric space propulsion systems, such as gridded and Hall effect thrusters, use xenon as the propellant gas. However, xenon is very rare and expensive to produce, and it is used in a number of competing industrial applications

Electric propulsion has been developed since the early 1960s, and its use onboard satellites, orbiting platforms, and interplanetary probes have increased significantly in the 21st century. The need for a detailed understanding of the working physics

Experimentally, two types of samples (carbon nanotube – CNT, NbSe2) were tested and both irradiated by γ-rays and nonirradiated at two temperature levels — room temperature (293 K) and liquid nitrogen temperature (78 K). The irradiated samples w

It is well known that supersonic flow around bodies with cavities located on the nose is accompanied by pulsation. A forward-facing cavity may be regarded as a resonance tube. The flow in forward-facing cavities have been the subject for many experim

Many researchers have studied pressure pulsations that arise in jets, separated flows, and bottom flows. Certain investigations devoted to oscillatory processes in Hartmann resonators were discussed. Such processes have been modeled by the method of

It has been shown in the previous investigations (Pradhan et al., 2002; Obolensky et al., 2011a, 2011b) that the postsynthesis treatment (e.g. chemical, heat treatment, milling, irradiation etc.) of single-walled carbon nanotubes (SWCNT) can essentia
