Ammonia−Water Cation and Ammonia Dimer Cation
The Journal of Physical Chemistry A, 2009We have investigated the structure, interaction energy, electronic properties, and IR spectra of the ammonia-water cation (NH(3)H(2)O)(+) using density functional theory (DFT) and high-level ab initio theory. The ammonia-water cation has three minimum-energy structures of (a) H(2)NH(+)...OH(2), (b) H(3)N(+)...OH(2), and (c) H(3)NH(+)...OH.

The pathways responsible for an the mechanisms underlying the adaptive increase in ammonia production in response to acidosis are considered. It seems unlikely that the cytosolic pathways (glutamine synthetase, glutaminase II, phosphate-independent glutaminase, and gamma-glutamyl transferase) are of primary importance in the adaptive process, but the ...

The role of ammonia in promoting ammonia borane synthesis
Dalton Transactions, 2016Mechanistic studies point toward added ammonia acting as a reagent while promoting the high-yielding synthesis of pure ammonia borane from sodium borohydride and ammonium salts.

Ammonia is a frequently used industrial agent. Ammonia is highly soluble in water and has toxic and corrosive actions caused by its alkalinity. It is easily absorbed through mucous membranes. Ammonia affects the upper airways more than the peripheral airways. Following exposure to ammonia, the clinical symptoms appear instantly and may consist of nasal

[Effect of Free Ammonia on Ammonia Escape During an Ammonia Oxidation Process].
Huan jing ke xue= Huanjing kexue, 2017This study used short process nitrification sludge to investigate the effect of high free ammonia (FA) on ammonia escape during ammonia oxidation. A sequencing batch reactor (SBR) was used to study the ammonia escape process under different FA concentrations.
