Latest Nitrogen oxide Stories
Could combustion without flames be used to build industrial gas turbines for power generation that are much more efficient than current models and produce almost no polluting emissions?
Chemists at the University of California, San Diego have discovered that a chemical reaction in the atmosphere above major cities long assumed to be unimportant in urban air pollution is in fact a significant contributor to urban ozoneâ€”the main component of smog.
By Fine, Philip M Sioutas, Constantinos; Solomon, Paul A ABSTRACT Secondary aerosols comprise a major fraction of fine particulate matter (PM^sub 2.5^) in all parts of the country, during all seasons, and times of day.
From catalytic converters to alternative fuels, the fight against big-city smog has for years been fought inside combustion engines and exhaust pipes. Now, scientists are taking the fight to the streets by developing "smart" building materials designed to clean the air with a little help from the elements.
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation.
