A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891.
Two physical systems are in thermal equilibrium if there are no net flow of thermal energy between them when they are connected by a path permeable to heat.
Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface.
Thomson scattering is the elastic scattering of electromagnetic radiation by a free charged particle, as described by classical electromagnetism.
A tokamak (Токамáк) is a device that uses a powerful magnetic field to confine a hot plasma in the shape of a torus.
Total electron content (or TEC) is an important descriptive quantity for the ionosphere of the Earth.
The Townsend discharge or Townsend avalanche is a gas ionisation process where free electrons are accelerated by an electric field, collide with gas molecules, and consequently free additional electrons.
Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.
The Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.
Upper-atmospheric lightning or ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines.
The Vlasov equation is a differential equation describing time evolution of the distribution function of plasma consisting of charged particles with long-range interaction, e.g. Coulomb.
Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.
In plasma physics, waves in plasmas are an interconnected set of particles and fields which propagates in a periodically repeating fashion.
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter.
Sir William Crookes (17 June 1832 – 4 April 1919) was a British chemist and physicist who attended the Royal College of Chemistry in London, and worked on spectroscopy.
The Z Pulsed Power Facility, informally known as the Z machine, is the largest high frequency electromagnetic wave generator in the world and is designed to test materials in conditions of extreme temperature and pressure.
