Plasma News

Plasma, often referred to as the fourth state of matter, is an ionized gas composed of positively charged ions and free electrons, which gives it unique electrical conductivity properties. Unlike solids, liquids, and gases, plasma does not naturally exist on Earth under normal conditions and must be generated by adding energy to a gas, such as by heating it to extreme temperatures or applying a strong electromagnetic field. Plasma is abundant in the universe, making up the majority of stars, including the sun, and is present in phenomena such as lightning and the auroras. On Earth, plasma has practical applications in various technologies, including neon signs, plasma TVs, and medical instruments for sterile processing. It is also crucial in advanced research fields, such as thermonuclear fusion, where scientists aim to harness the same reactions that power the sun as a potent and clean energy source.
