Plasma polymerization (or glow discharge polymerization) uses plasma sources to generate a gas discharge that provides energy to activate or fragment gaseous or liquid monomer, often containing a vinyl group, in order to initiate polymerization.
The simplest type of glow discharge is a direct-current glow discharge. In its simplest form, it consists of two electrodes in a cell held at low pressure (0.1–10 torr; about 1/10000 to 1/100 of atmospheric pressure).
Aerolux Light Corporation was a manufacturer of artful gas-discharge light bulbs from the 1930s through the 1970s. [1] Aerolux made these bulbs in a factory in New York City . US Patents dating back to the 1930s describe the design and construction of these bulbs.
Glow-discharge optical emission spectroscopy (GDOES) is a spectroscopic method for the quantitative analysis of metals and other non-metallic solids. The idea was published and patented in 1968 by Werner Grimm from Hanau, Germany .
The A-D region is called a dark discharge; there is some ionization, but the current is below 10 microamperes and there is no significant amount of radiation produced. The F-H region is a region of glow discharge; the plasma emits a faint glow that occupies almost all the volume of the tube; most of the light is emitted by excited neutral atoms.
Nitrogen glow Oxygen glow Electrical discharge in air Particle beam from a cyclotron. Ionized-air glow is the luminescent emission of characteristic blue–purple–violet light, often of a color called electric blue, by air subjected to an energy flux either directly or indirectly from solar radiation.
Chemiluminescence kites, [17] emergency lighting, glow sticks [18] (party decorations). Combustion analysis: Certain free radical species (such as • CH and • OH) give off radiation at specific wavelengths. The heat release rate is calculated by measuring the amount of light radiated from a flame at those wavelengths. [19] Children's toys ...
A glow discharge is a plasma-containing apparatus in which the plasma is formed by a large voltage placed across a rarefied gas. Glow discharges are used for electric lighting and materials processing. In a glow discharge, ionization instability takes the form of striations, [1] or bands of enhanced and suppressed light production. The distance ...
