Within the context of food processing the term "cold" can potentially engender misleading images of refrigeration requirements as a part of the plasma treatment. However, in practice this confusion has not been an issue. "Cold plasmas" may also loosely refer to weakly ionized gases (degree of ionization < 0.01%).
The understanding gained from studying plasma treatment of skin diseases, may also help to develop new Plasma Medicine strategies to treat internal organs. [35] Cold plasma is used to treat chronic wounds. Preliminary results indicate that cold plasma therapy can be more effective than the gold standard. [36]
Microplasma is a subdivision of plasma in which the dimensions of the plasma can range between tens, hundreds, or even thousands of micrometers in size. The majority of microplasmas that are employed in commercial applications are cold plasmas. In a cold plasma, electrons have much higher energy than the accompanying ions and neutrals.
Plasma treatment is a surface modification process for textiles that imparts various functional properties at a lower cost, with fewer chemical adverse effects, and with a reduced environmental impact all while maintaining important textile properties.
Plasma Surgical is a privately held medical device company with headquarters in suburban Atlanta, Georgia, USA, with operations in the UK and France.The company was founded based on the work of plasma physics professor Nikolay Suslov, who developed a technology to apply plasma energy to surgically treat live tissue with minimal thermal damage.
The efficiency of the plasma generation reaches 90%, while the remaining 10% of the power is lost due to mechanical and dielectric heating of the piezoelectric transformer. Due to low electric currents, typical for the dielectric barrier and the corona discharges, the piezoelectric direct discharge produces a non-equilibrium plasma.
Depending on the power of the jet, the plasma beam can be up to 40 mm long and attain a treatment width of 15 mm. Special rotary systems allow a treatment width per jet tool of up to 13 cm. [11] Depending on the required treatment performance, the plasma source is moved at a spacing of 10–40 mm and at a speed of 5–400 m/min relative to the ...
Plasma cleaning is the removal of impurities and contaminants from surfaces through the use of an energetic plasma or dielectric barrier discharge (DBD) plasma created from gaseous species. Gases such as argon and oxygen , as well as mixtures such as air and hydrogen/nitrogen are used.
