Trees, both the anthropogenic and non-anthropogenic ones together, are estimated to emit
as much or more methane than the 200 million tonnes assumed to be generated by the two major sources of anthropogenic methane--energy production and domesticated animals--combined.
Gasification also works on municipal and hazardous wastes, neither of which emit
carbon dioxide when burned.
The 112(g) rule applies to new or reconstructed emission units that have the potential to emit
more than 10 tons/year of any single HAP or 25 tons/year of the combination of all HAPs.
In a "Serious" air-pollution region, you're a major" polluter if you emit
only 50 TPY, and you have nine years to clean up your act.
The same tools emit
nearly a ton per day of nitrogen oxide and 182 tons per day of carbon monoxide - two major components of smog.
While most FRP processors might doubt that they emit
that much styrene per year, SPI provided two illustrative examples:
com) will build the first biodiesel plant to emit
almost zero net Global Warming Gases (GWG)(CO(2)) from direct plant production of biodiesel.
A material that absorbs strongly at a specific wavelength when cool will emit
strongly at that same wavelength when heated.
When excited by laser beams entering from outside the cavity, the atom initially emits
Because OSRAM's thin-film chip emits
light only from its top surface, the resultant high chip luminance can increase the optical system efficiency and reduce the size of optics for lighting applications.
Pioneered in 1989 by optical innovator Jack Jewell, Picolight's founder and chief technology officer, VCSEL technology emits
light vertically through the surface of a wafer -- rather than through its edges, as with other edge-emitting Fabry-Perot (FP) and differential feedback (DFB) lasers.
Each type of ion emits
light at a specific wavelength, which under tamer conditions would show up as a narrow line in the quasar's spectrum.
In a triumph of engineering, the Bell Labs team overcame this challenge by using the precise light-controlling qualities of a photonic crystal to create a QC laser that emits
photons perpendicular to the semiconductor layers, resulting in a laser that emits
light through its surface.
An ordinary laser emits
only a single color because it's built with a light-emitting substance that naturally generates one wavelength of light when energized.
The new OLED display device described in the patent incorporates an addressable two-dimensional matrix of organic light emitting diodes that emits
monochrome light, a CCM element capable of absorbing the monochrome light and re-emitting that light at different wavelengths, and cover element.
