Wonders of Plasma

In physics, the term “Plasma" refers to a quasi-neutral Iionized gas, or a gas in which a specific percentage of particles are charged.

Plasma becomes a highly conductive gas that reacts quickly to electromagnetic fields when charged species are present. Because of its significant differences from the properties of the solid, liquid, and gaseous states of matter, plasma is also referred to as the "fourth state" of matter. At present, plasma has proven to be a biggest wonder towards technological applications. Plasma technology is commonly used in many industries, including in the automotive, microelectronics, packaging, medical device industries, materials processing and pollution control etc. The most important practical applications of plasmas lie in the future, largely in the field of power production.It can help make features on chips for computers. Plasma is also used in making transmitters for microwaves or high-temperature films. It can even be used in work with minerals such as diamond, and in extracting economically valuable metals from rock. Plasma technologies have a wide range of applications, from creating stunning neon signs to propelling spacecraft. In the semiconductor industry, plasma processes are critical for manufacturing high-quality electronic devices with precision and efficiency. The multidisciplinary field of plasma medicine focuses on the therapeutic uses of plasma, or ionized gas, including wound healing, cancer treatment, and disinfection. Here, a form of plasma in terms of dielectric barrier discharge is discussed towards pollution control.
