Anotations

Scope note:

Plasma in which the temperature of the individual constituents differ from one-another. Electrons are at higher temperature (more than 10,000K) and neutral atoms are at room temperature. However, the density of the electrons in the plasma is very low compared to the density of the neutral atoms. Cold plasma technology offers an approach to decontaminating or restoring materials by removing oxides, chlorides, and other corrosive salts as well as rendering fungi and bacteria inert.
