Plasma Technology To Simplify Your Life
The newly emerging technology based on Plasma is growing fast in many aspects of process - a better and simple processes are expected to make a better living of human beings.
It is very easy to make by using an electrical voltage. As a simple example, face two electrodes in the air. Air is an insulator, can't deliver an electrical current. If we give a high voltage between two electrodes then the nature of conductor will appear in the air, which means the electric current begins to flow. The flow of electrical current shows that the ionization process occurred and resulting the formation of ions and electrons. The action reaction that occurs between ions and electrons in large quantities is causing the condition of the air between two electrodes is neutral, this is plasma. In short, plasma is a collection of free electrons, ions and free atoms. For an example of plasma is the ionization of hydrogen : H2 --> H+ + H+ + 2e- Several chemically and physically processes occurred during plasma generation. Plasma can act as source of chemical catalyst, heat and energetic ion. Plasma discharge both in air and water are efficient in the formation of chemically active species such as NO3, OH, O3,H2O2, etc. In addition, shockwaves,ultraviolet light, cavitation may also be formed. These reactive species and the physical processes, in turn, have been shown to rapidly and efficiently degrade a number of volatile organic compound. Examples of the use of plasma in daily life are TV plasma and AC plasma.
