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 ...

Scientists from Tokyo Metropolitan University have developed a low-temperature catalyst for removing NOx gas from industrial exhaust using ammonia. Composed of bulk "defective" vanadium oxide instead ...

Traffic contributes more to nitrogen oxide emissions in Europe than previously thought, a new study shows. The research team shows that even newer air quality models underestimate traffic related ...

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 ...

Industry produces gases that are harmful to both humans and the environment and therefore must be prevented from escaping. These include nitric oxide and nitrous oxide, the latter also known as ...

A research team has developed a new strategy to improve catalysts used to remove nitrogen oxides from industrial emissions. By using ethanol during catalyst preparation, the scientists significantly ...

Take two snowballs, one in each hand. Let each snowball represent an atom of nitrogen. Gently press the snowballs together so they stick. The two atoms, stuck together, comprise a molecule of nitrogen ...

FPL's Indiantown plant released carbon dioxide, nitrogen oxides and other toxic pollutants over the past decade.

A southern Indiana chemical plant released an orangish cloud of nitrogen oxide Tuesday, prompting officials to close nearby roads and issue shelter-in-place orders until the cloud dissipated.

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 ...
