Plasma chemistry is the branch of chemistry that studies chemical processes in low-temperature plasma, including the laws that govern reactions in plasma and the fundamentals of plasma chemical technology. Plasmas are artificially produced in plastrons at temperatures that range from 103 to 2 × 104 K and pressures that range from 10 to 104 atmospheres. Interaction between the reagents in plasma results in the formation of final, or terminal, products; these products can be removed from the plasma by rapid cooling, or quenching. The basic feature of all plasmochemical processes is that reactive particles are generated in significantly higher concentrations than under ordinary conditions of chemical reactions. The reactive particles that are produced in plasma are capable of effecting new types of chemical reactions; the particles include excited molecules, electrons, atoms, atomic and molecular ions, and free radicals. Indeed, some of these particles can only exist in the plasma state.
Plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons. The characteristics of plasmas are significantly different from those of ordinary neutral gases so that plasmas are considered a distinct "fourth state of matter”. Plasmas are described by many characteristics, such as temperature, degree of ionization, and density, the magnitude of which, and approximations of the model describing them, gives rise to plasmas that may be classified in different ways.
Plasma in liquids usually has high dielectric constants and high dielectric strength than gas phases which are useful in various biological, environmental and medical technologies. The process of using plasma in liquids is followed by electric breakdown of liquids is initiated by the application of high electric field on the electrode, followed by rapid propagation and branching of plasma channels. Typically plasmas are only considered to exist through the ionization of gases and typical production of plasmas in liquids generates bubbles through heating or via cavitation and sustains the plasmas within those bubbles.
Plasma diagnostics are a pool of methods, instruments, and experimental techniques used to measure properties of plasma, such as plasma components density, distribution function over energy (temperature), their spatial profiles and dynamics, which enable to derive plasma parameters. Plasma diagnostic techniques are also used to observe physical processes that reveal parameters that characterize plasma. These parameters include spatial and temporal distributions of constituent particle densities and temperatures and localized magnitudes of electric and magnetic fields. The techniques used include those that have applications in other areas of science and those that have been developed for their unique applications to plasmas.
Plasma processing is a plasma-based material processing technology that aims at modifying the chemical and physical properties of a surface. Plasma processing techniques include: Plasma activation, Plasma etching. Plasma processing of materials is also a processing technology which is used in aerospace, automotive, steel, biomedical, and toxic waste management industries it is also been utilized increasingly in the emerging technologies of diamond film and superconducting film growth.
Plasma spectroscopy is a study of electromagnetic radiation emitted from ionized media. The plasma will be considered to have a temperature and degree of ionization sufficiently high so that the radiation is due to atomic rather than molecular processes. In contrast to conventional spectroscopy where it is interested in the atomic structure of an isolated atom, the radiation from plasma depends, not only on the properties of the isolated radiating species, but also on the properties of the plasma in the immediate environment of the radiator. This dependence on the plasma properties is a consequence of the fact that ions and electrons interact with other species via the long-range Coulomb potential.
Plasma nanotechnology is a branch of technology that deals with dimensions and tolerances of less than 100 nanometres, especially the manipulation of individual atoms and molecules. Low-temperature plasmas find numerous applications in growth and processing of nanomaterials such as carbon nanotubes, inorganic nanowires and others. Nanotechnology and Nanomaterial’s are also key approaches to improve the performance of energy storage technologies.
Applied Plasma Technologies (APT) develops and manufactures plasma assisted combustion systems for reliable ignition, flame control, clean and stable combustion of different fuels in gas turbines, high speed propulsion systems, boilers, technological burners, flare stacks, chemical plants, landfills. APT also conducts research and development in some new fields as gaseous, liquid and solid fuels reformation and hydrogen production, high purity silicon production, waste into power processing, non-equilibrium plasma coating and surface treatment, plasma aerodynamics, air and water treatment, IC engine improvements.
Plasma has achieved significant importance in a diversity of research and these plasmas are routinely used to clean and surface treat plastic automotive bumpers, performance textiles and filter media, stainless steel syringe needles, angioplasty balloon catheters, plastic lenses, Golf balls and many other diverse products. In fact, it would be difficult to identify a modern product that has not benefitted from plasma processing at some stage during its fabrication.
The number of potential applications of non-equilibrium atmospheric pressure discharges in biology and medicine has grown and activity in this direction lead to the formation of a new field in plasma chemistry titled 'Plasma Medicine'. Some examples of medical applications of plasma are the use of plasma in the treatment of dental cavities, sterilization of various surfaces, treatment of skin diseases, delicate surgeries and many other applications. It is now clear that these plasmas can have not only physical (e.g. burning the tissue) but also medically relevant therapeutic effects; plasmas can trigger a complex sequence of biological responses in tissues and cells. The development of actual commercial tools that will enter the hospital, and in finding novel and perhaps even unexpected uses of these plasmas, an understanding of the mechanisms of interaction of non-equilibrium gas discharges with living organisms, tissues and cells becomes essential.
Plasma physics is the branch of physics that deals with plasmas and their interactions with electric and magnetic fields of charged particles and fluids interacting with self-consistent electric and magnetic fields. It is a research that has many different areas of application such as space and astrophysics, controlled fusion, accelerator physics and beam storage.
