It is the emission of heat-trapping gases including carbon dioxide, not industrial toxic dust.
Luminescence is the emission of light by certain materials when they are relatively cool.
The result is the emission of radio waves into space (see electromagnetic radiation: Generation of electromagnetic radiation).
The secondary reaction is the emission of electrons from molecules, which leads to the formation of cation radicals, which serve as the intermediate to PAHs.
The fundamental principle behind CRT displays is the emission of a controlled stream of electrons that strike light-emitting phosphors coating the inside of the screen.
ESCA depends on a fundamental phenomenon, the photoelectric effect, which is the emission of electrons that occurs when electromagnetic radiation strikes a material.
A special feature of a nuclear explosion is the emission of nuclear radiation, which may be separated into initial radiation and residual radiation.
Mechanoluminescence (ML) is the emission of light consecutive to a mechanical force or stress imposed to a crystalline material.
The main environmental problem caused by the production of energy from coal combustion is the emission of CO2.
One of the causes of pollution associated with the construction of transportation infrastructures is the emission of greenhouse gases into the atmosphere.
In 1905 Einstein extended Planck's hypothesis to explain the photoelectric effect, which is the emission of electrons by a metal surface when it is irradiated by light or more-energetic photons.
