General description
Nitric acid is generally used as a primary reagent for the nitration and oxidation of organic molecules. It is also used as a strong oxidizing agent in organic synthesis to perform oxidative transformations. In addition, nitric acid is also used in the manufacturing of intermediate for polyurethanes and polyamides production.
Application
Nitric acid is used:
- As an oxidizing agent with sulfuric acid to graft the carboxylic acid over CNT (carbon nanotubes) to produce CNT-COOH.
- In the combustion method to adjust the pH of the solution to 7. It is one of the steps in the preparation of mixed magnetite–hematite nanoparticles.
- As a nitrating agent with sulfuric acid in the synthesis of 8-nitro-7-hydroxy-4-methyl coumarin and 6-nitro-7-hydroxy-4-methyl coumarin from 7-hydroxy-4-methyl coumarin.

Uncontrolled reactions in biological media are a main obstacle for clinical translation of V-based anti-diabetic or anti-cancer pro-drugs. We investigated the use of controlled-release pharmaceutical formulations to ameliorate this issue with a series of V(V) and (IV) complexes of anionic

The fate of NO(x) (=NO + NO(2)) is important to understand because NO(x) is a significant player in air quality determination through its role in O(3) formation. Here we show that renoxification of the urban atmosphere may occur through the

The unique physical and chemical properties of nanomaterials have led to their increased use in many industrial applications, including as a paint additive. For example, titanium dioxide (TiO2) engineered nanoparticles (ENPs) have well-established anti-UV, self-cleaning, and air purification effects. Silver
