The atmosphere is mostly nitrogen (approximately 80%) and oxygen (approximately 20%). The remaining gases are found in much smaller proportions, such as carbon dioxide and water vapour.

Air pollution is even more dangerous than previously thought, the World Health Organization (WHO) has warned, as it slashes maximum safe levels of key pollutants such nitrogen dioxide. An ...

An ecologically realistic 24-year field study of grasslands showed that elevated levels of carbon dioxide nearly tripled species losses attributed to nitrogen pollution. Dozens of studies have ...

But whether rising levels of climate-warming carbon dioxide gas are amplifying those nitrogen-induced biodiversity losses or dampening them remains unclear and is an understudied topic.

Award Citation: For developing innovative synthetic methods affording complexes containing multiple bonds between carbon, nitrogen ... conversion of carbon dioxide to chemical fuels driven by ...

Carbon dioxide lasers in particular are comprised of the following components: When electrical current is introduced to the gain medium, the nitrogen molecules are excited to a vibrational state.

Carbon dioxide (CO 2) comes from both natural sources (including volcanoes, the breath of animals and plant decay) and human sources (primarily the burning of fossils fuels like coal, oil and natural ...
