Nitrogen oxides (NOx) are some of the most significant pollutants in our atmosphere—they contribute to the formation of smog, acid rain and ground-level ozone. Because of this, combustion researchers ...

NOx is a generic term for the various nitrogen oxides produced during combustion. They are believed to aggravate asthmatic conditions, react with the oxygen in the air to produce ozone, which is also ...

Currently there are no standards or limits for indoor air levels of nitrogen oxides; for reference, levels in homes without combustion appliances are typically half of outdoor levels, while homes with ...

Even outfitted with the best available technologies, gas-turbine power plants and industrial boilers emit significant amounts of nitrogen oxides, precursors to smog and acid rain. But better results ...

Just a couple decades ago, nitrogen oxide emissions routinely plagued cities’ skies and their residents’ lungs. These polluting reactive nitrogen oxide gases from the tailpipes of combustion-engine ...

We know that reducing emissions from cars and factories is essential for cleaning our air, but new research reveals a ...

A satellite survey has revealed that farmlands may have a bigger impact on air pollution and ground-level ozone than previously thought. Lyatt Jaeglé from the University of Washington in Seattle and ...

For decades, combustion researchers and engine companies have been seeking to understand how these gases are produced during combustion so that they can find ways to reduce them. Now researchers have ...
