In this paper analysis and generalization of the scientific and educational properties of information textbooks on nano-electronics, created from the scientists of the Institute of Electronics at Bulgarian Academy of Sciences, ...
Micro-arc oxidation (MAO) technology allows getting ceramic coatings of Al2O3 with composition, structure and properties controlled over a wide range and using them as wear-resistant, corrosion- resistant, heat- resistant ...
Plasma density is estimated from the target voltage and current characteristics of the pulse modulator circuit in plasma-based ion implantation. The voltage recovery time constant directly reflects the ion sheath characteristics, ...
A main purpose of sterilization is to kill the harmful microorganisms. In food industry, the representatives of microorganisms which are difficult to sterilize are spore-forming bacteria. Because these bacteria are extremely ...
Plasma-based ion implantation is a recently developed technique used to modify the surface of materials by immersion in plasma coupled with the application of a negative bias voltage.
In this study, we compare the properties ...
Plasma base ion implantation (PBII) with self-ignited plasma generated by only pulsed voltages to the test specimen has been applied to the sterilization process. We found that the PBII process reduced the numbers of active ...
Plasma based ion implantation (PBII) with high negative pulsed voltage applied to the test specimen has been applied to the sterilization process as a technique suitable for three-dimensional work pieces. We found that the ...
It is shown that the laser scalpel can easily and without any mechanical force cut both soft and hard (bone) living tissue. This is a low-impact operation with cutting width – 0.1 … 0.5 mm. Evaporation mechanism ...
Considered are the technologies of laser and laser-microplasma alloying of surface layers of 38KhN3MFA structural steel specimens with introduction of powder filler materials based on tungsten and chromium carbide, promoting ...
