Nitric acid is a notoriously strong and chemically destructive compound found in water on earth and in our atmosphere. However, a team of researchers have found that its punch is much weaker when it ...

Nitric acid and ammonia are the two important reactive forms of nitrogen, which are widely used in human life and production. In 2017, the worldwide production of HNO3 and NH3 was estimated to be 50 ...

Because nitric acid is stable, long-lived, and not photochemically reactive, it’s long been thought to be the final destination for reactive nitrogen species in the atmosphere. But those assumptions ...
