atmospheric plasma

Atmospheric plasma is an ionized state of matter created at or near room temperature in the air. It consists of energized particles like ions, electrons, and neutral molecules, forming a conductive, highly reactive environment. This plasma can be generated using electrical discharges, such as corona or dielectric barrier discharges, and is used in applications like surface sterilization, air purification, and material treatments. Because it operates at atmospheric pressure and relatively low temperatures, it is practical for various industrial and medical uses without the need for vacuum chambers or extreme cooling.
