Polymerization is not a plasma-chemical reaction, but rather a chemical reaction that occurs in the presence of a plasma.

Electricity is the primary source of energy in a plasma-chemical reaction, as it is used to generate the plasma.

Food processing is not a common application of plasma chemistry, although it is an emerging area of research.

Plasma chemistry offers several advantages for surface modification, including its non-contact nature, its ability to modify a wide variety of materials, and its low-temperature operation.

Laser-induced plasma is not a common type of plasma-chemical reactor, although it is used in some specialized applications.

The development of plasma-chemical processes faces several challenges, including the high cost of plasma generation, the difficulty in controlling the plasma chemistry, and the lack of understanding of plasma-chemical reactions.

X-ray diffraction is not a common diagnostic technique used in plasma chemistry, although it can be used to characterize the structure of plasma-deposited thin films.

Plasma chemistry offers several advantages for thin film deposition, including the ability to deposit a wide variety of materials, the ability to deposit thin films with high purity, and its low-temperature operation.

Plasma chemistry is not commonly used for the removal of particulate matter (PM), although it is used for the removal of volatile organic compounds (VOCs), nitrogen oxides (NOx), and sulfur oxides (SOx).

The development of plasma-chemical processes for pollution control faces several challenges, including the high cost of plasma generation, the difficulty in controlling the plasma chemistry, and the lack of understanding of plasma-chemical reactions.
