But in recent years, more and more attention has been directed to the properties of matter in a fourth and unique state, which we call plasma. It is likely that more than 99% of the matter in the visible universe is in the form of plasma. But quantum plasmas are also important in metallic and semiconductor nanostructures as well as in super-dense astrophysical environments. In recent years, plasma science and technology have gained increasing interest for synthesis, processing, nanoparticle structure, textile surfaces, alloy formation, etching, etc. A major field of plasma technology is gas conversion (including CO2, CH4, and N2) into value-added chemicals or renewable fuels. Moreover, plasma is generated by electric energy and is very suitable for catalyst preparation at low temperatures, as well as for requirements for sustainable agriculture. Many researchers are experimenting with plasma to make a new kind of nuclear power called fusion, which would be much better and safer than ordinary nuclear power and produce much less radioactive waste.

Introduction The United Nations defines sustainable development as "meeting the needs of the present without compromising the ability of future generations to meet their own needs." Thus, sustainability requires us to protect both natural resources and human health while using our available resources efficiently. Recently, plasma has become very important for a sustainable future. First and foremost, the term plasma represents a macroscopically neutral gas containing many interacting charged particles (electrons and ions) and neutrals. Basically, plasma is a quasi neutral gas of charge and neutral particles that exhibits collective behavior due to long-range Coulomb forces. The quasi-neutrality of plasma implies that the electron density is approximately equal to the ion density. The collective behavior implies that the motion of species depends not only on the local conditions but also on the state of the plasma far away from the point of interest [1]. However, any ionized gas can’t be called a plasma; to Copyright © 2023, Scholarly Research Journal for Interdisciplinary Studies
