bionics
The application of observed operational processes of sophisticated living organisms to mechanical and electrical systems in order to analogize capabilities or efficiency.
thermionic diode
A diode electron tube that contains a heated cathode.
thermionic emission
The emission of free electrons by a rise in temperature of the cathode alone.
electron-gun system
An electron-gun system is an assembly used to generate and control a focused beam of electrons. Electron guns find applications in various fields, including cathode ray tubes (CRTs), electron...
gold colloid aggregates
Gold colloid aggregates refer to clusters or assemblies of gold nanoparticles suspended in a liquid medium. These aggregates are formed when individual gold nanoparticles come together due to various...
halide
In chemistry, a halide refers to a chemical compound containing one or more halogen atoms bonded to another element. The halogens are a group of elements in the periodic table that includes fluorine...
JIAWG
joint integrated avionics working group
klystron
A thermionic tube that has a velocity-modulated electron stream and that may be used as a microwave amplifier or oscillator.
optical clock
An optical clock is a highly precise and advanced timekeeping device that relies on the oscillations of electromagnetic radiation in the optical or ultraviolet part of the electromagnetic spectrum....
Q machine
Device in which contact ionization of atomic particles and thermionic electron emission are used to produce magnetically confined plasma that is greatly ionized.
vacancy
In an ionic crystal, the region in the crystal lattice where the ion, predicted to be present, is absent.
Van der Waals
Van der Waals forces refer to the attractive or repulsive forces between molecules (or parts of molecules) that arise from fluctuations in electron distribution. These forces are relatively weak...
video detector
A device, such as a thermionic or crystal diode, that is introduced into the vision channel of a television receiver to select the signal from the intermediate-frequency carrier.
