ammonium (redirected fromNH4+) Thesaurus Medical Encyclopedia Related to NH4+:Hco3,NO3 am·mo·ni·um (ə-mō′nē-əm) n. The univalent chemical ion NH4+, derived from ammonia, whose compounds chemically resemble the alkali metals. ...
NH4 ions are usually generated from ammonia or ammonium-containing chemicals. We herein present a simple method for generating NH4 reagent ions in the hollow cathode glow discharge ion source that nowadays most proton-transfer-reaction mass spectrometry (PTR-MS) instruments are equipped with. We ...
The vibrational frequency shift of ammonium molecules have been investigated along with the frequency characteristics depending on the presence/absence of outer-shell ammonia molecules. In this study, the calculated binding energies and the characteristic NH stretching vibrational frequency shift are in ...

Yellow polyhedra of the title phase are prepared from a reaction of La and S-8 in supercritical ammonia at 170 degrees C for 3 days. It crystallizes in the orthorhombic space group Pnma with lattice parameters of a=16.622(4), b=15.739(3), c=7.626(2)Angstrom, V=1994.9(8)Angstrom(3),...
Ammonium (NH4+), a key nitrogen form, becomes toxic when it accumulates to high levels. Ammonium transporters (AMTs) are the key transporters responsible for NH4+ uptake. AMT activity is under allosteric feedback control, mediated by phosphorylation of a
The Online Ammonia Nitrogen Analyzer reliably and accurately measures ammonia concentration in a variety of applications, including raw water monitoring and nutrient removal from wastewater. No reagents are required, they are green and non-polluting, and they can be monitored online in real-time. The...
