Aplicación

Ammonia may be used as a base to adjust pH for preparing mixed magnetite-hematite nanoparticles via combustion method. These nanoparticles show promising potential as sorbents for removing heavy metal ions from water.
Anhydrous ammonia has been used in dynamic reaction cell technology (DRC) to remove interfering ions without the loss of sensitivity. It has also been used for adjusting pH during the synthesis of magnetite-hematite mixture by combustion methods.
Reagent for chemical vapor deposition of TiN.

Recent studies suggest that alkalinizing treatments improve the course of chronic kidney disease (CKD), even in patients without overt metabolic acidosis. Here, we tested whether a decreased ability in excreting urinary acid rather than overt metabolic acidosis may be deleterious

Molecular Layer Deposition of Organic and Hybrid Organic-Inorganic Polymers

Atomic layer deposition (ALD) techniques have emerged in the last ten years to meet various needs including semiconductor device miniaturization, conformal deposition on porous structures and coating of nanoparticles. ALD is based on two sequential self-limiting surface reactions.
