I thought plasma was the most energetic state of matter, and that heat is proportional to energy levels? How is it possible for cold plasma then?
As I recall, any highly ionized gas can be called a plasma, and what's that stuff in plasma tvs?
nightcleaner said:The word Plasma may also be used to describe a more fundamental grouping of particles, such as the electron flux in a spark discarge, whethor from a Van de Graff generator or from any other generator, battery, etc. This type of plasma involves only electrons (or other fundamental particles) and is not made up of atoms at all.
nightcleaner said:Plasma then in general refers to a gas or liquid which carries charged particles.
Cold plasma is a partially ionized gas that exists at low temperatures. It is also known as non-thermal plasma because it does not reach thermal equilibrium with its surroundings.
Cold plasma is created by applying energy to a gas through various methods, such as electrical discharges, microwaves, or lasers. This causes the gas particles to become ionized and form a plasma state.
Cold plasma has unique properties, such as high reactivity and low temperature, that make it useful in various applications. It can generate reactive species, such as ions and radicals, that can be used for surface modification, sterilization, and other industrial processes.
Cold plasma has a wide range of applications, including surface treatment in manufacturing, sterilization of medical equipment, and environmental remediation. It is also used in the production of semiconductors and in research for energy and space exploration.
Yes, cold plasma is generally considered safe when handled properly. It operates at low temperatures, so there is minimal risk of burns or fire. However, precautions should be taken when handling and operating equipment that produces cold plasma.
