Monoammonium Trimetaphosphimate (NH4)H2(PO2NH)3
Trimetaphosphimates show a rich structural variability in both cation coordination and anion arrangement. They are precursors for crystalline, as well as amorphous oxonitridophosphates. The ammonium trimetaphosphimate (NH4)H2(PO2NH)3 is formed during the

Potentiometric measurements using NH4+ -ion selective electrodes in aqueous solutions
, 2011 Byla popsána potenciometrická měření s využitím tří zvolených NH4+ - iontově selektivních elektrod. Diskutováno bylo jejich chování s ohledem na změny koncentrace NH4Cl a KCl , jakož i změny pH nebo teploty. Potvrzena byla aplikovatelnost zmíněných NH4+ -

Plant, Cell and Environment, 2022 Rice is known for its superior adaptation to ammonium (NH4+ ) as a nitrogen source. Compared to many other cereals, it displays lower NH4+ efflux in roots and higher nitrogen-use efficiency on NH4+ .

Thermal decomposition of (NH4)2MoO2S2, (NH4)2MoS4, (NH4)2WO2S2 and (NH4)2WS4
Journal of Inorganic and Nuclear Chemistry, 1973Abstract The thermal decomposition of (NH 4 ) 2 MoO 2 S 2 ,(NH 4 ) 2 MoS 4 , (NH 4 ) 2 WO 2 S 2 and (NH 4 ) 2 WS 4 has been studied by DTA and TGA methods. All compounds decompose in two steps. The tetrathio compounds decompose as represented by the equations, (NH 4 ) 2 MeS 4 → 2NH 3 + H 2 O + MeS 3 MeS 3 → MeS 2 + S (Me Mo, W).

The rate of hydrolysis of (NH4)2RuNOCl5 and (NH4)2RuNOCl4OH
Inorganica Chimica Acta, 1972The rates of hydrolysis of (NH4)2RuNOCl5 and (NH4)2RuNOCl4OH have been measured at an ionic strength of 0.50 over a wide range of temperatures and pH. All reactions studied were first order in complex. The rate of hydrolysis of (NH4)2RuNOCl5 was more rapid in basic solution than in acid solution by 25–50%.

Neutron scattering study of NH4+ motion in NH4+ β-alumina
Solid State Communications, 1977Abstract Incoherent inelastic neutron scattering has been used to study the motion of NH 4 + ions in NH 4 + β-alumina. The results establish that jump reorientation of NH 4 + ions is rapid compared to translational diffusion: The data are consistent with thermally activated jumps between equivalent NH 4 + orientations with a proton jump ...
