Nitrous oxide is a colorless, odorless gas with the chemical formula N2O. It is commonly used in medical and dental settings as an anesthetic agent, as well as in the food industry as a propellant. Nitrous oxide is also a potent greenhouse gas, contributing to global warming and ozone depletion. Research in the area of nitrous oxide focuses on studying its sources, distribution, and impact on the environment, as well as developing strategies to mitigate its emissions and reduce its environmental impact.
