Nitric Acid: Nitric acid (HNO3). A colorless liquid that is used in the manufacture of inorganic and organic nitrates and nitro compounds for fertilizers, dye intermediates, explosives, and many different organic chemicals. Continued exposure to vapor may cause chronic bronchitis; chemical pneumonitis may occur. (From Merck Index, 11th ed)
nitric acid : A nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms.

Nitric acid (HNO3) vapor is an important nitrogenous air pollutant responsible for increasing saturation of forests with nitrogen. Nitric acid maceration is a rediscovered technique for identifying the nervous anatomy of soft tissues.
Nitric acid (NO) has been implicated in the mechanisms of seizure activity and neurodegeneration, which are both very active in the PEHO syndrome. Nitric acid has been used to extract plastic particles from zooplankton.

The nitric acid pretreatment generated the most hemicellulose hydrolyzate, while significant reduction of the lignin occurred with sodium hydroxide pretreatment. Nitric acid treatment results in an increase in adsorption capacity of fly ash (2.4 x 10(-5) mol/g) while it decreases the adsorptive capacity for red mud (3.2 x 10 (-6) mol/)

Smear Layer Adherent debris produced when cutting the enamel or dentin in cavity preparation.
