An ammonium/bis-ammonium switchable molecular shuttle

Tetrahedron, 2008
A pH shuttle has been developed in which the mean position of the macrocycle can be switched between dialkylammonium stations of differing acidities. With only the most basic binding site protonated (dibenzylammonium), the macrocycle resides almost exclusively on the protonated station; when the second ammonium group (diethylammonium) is generated by ...

Density and viscosity of ammonium nitrate, ammonium nitrate–potassium chloride and ammonium nitrate—ammonium phosphate melts

Journal of Applied Chemistry, 1967
AbstractThe results of density and viscosity measurements are given for ammonium nitrate and the salt mixtures ammonium nitrate—potassium chloride and ammonium nitrate‐ammonium dihydrogen phosphate. The latter system is complicated because of the formation of non‐ortho phosphates and the results obtained refer to the equilibrium mixture obtained after ...

Characterization of ammonium absorption by ammonium-preferential cassava

Journal of Plant Physiology
Cassava plants can adapt to poor soils where most other crops are unable to grow normally, suggesting that they are able to efficiently uptake and utilize nutrient elements from the soils. However, little is known about the mechanism of nutrient efficiency in the crop.

Scattering of Cold Neutrons in Ammonium Carbonate, Ammonium Citrate, and Ammonium Acetate

The Journal of Chemical Physics, 1967
Neutron-energy-gain spectra have been measured in (NH4)2CO3, (NH4)2HC6H5O7, and NH4C2H3O2 at 20°C using the Brookhaven slow-chopper facility. Each spectrum exhibits two peaks that are characteristic of optical modes. The spectra of ammonium carbonate and ammonium citrate are similar to those of the body-centered-cubic lattice phase of the ammonium ...

Ammonium perchlorate and ammonium perchlorate-binder sandwich combustion

12th Aerospace Sciences Meeting, 1974
order of 300 \i in width. The deflagration of all three burners appeared laminar, with a definite temperature peak above the center of the burner. The PP-COMM AP had a scalloped surface which accounted for a more unsteady appearance of the gas flow above the deflagrating AP. A yellow-green zone was visible within the SC-UHP AP extending from the burner

Heterogeneous Reactions of Alkylamines with Ammonium Sulfate and Ammonium Bisulfate

Environmental Science & Technology, 2011
The heterogeneous reactions between alkylamines and ammonium salts (ammonium sulfate and ammonium bisulfate) have been studied using a low-pressure fast flow reactor coupled to an ion drift-chemical ionization mass spectrometer (ID-CIMS) at 293 ± 2 K. The uptake of three alkylamines, i.e., monomethylamine, dimethylamine, and trimethylamine, on ammonium

Ammonium Perchlorate and Ammonium Dihydrogen Phosphate as Energetic Materials: Comparison to Ammonium Nitrate

The Journal of Physical Chemistry C, 2019
Ammonium perchlorate (NH4ClO4) and ammonium dihydrogen phosphate (NH4H2PO4) are investigated through laser ablation/matrix-assisted laser desorption ionization processes, anion photoelectron spectroscopy (PES), and density functional theory calculations. No parent anionic species are observed in the mass spectra of these two energetic species. Instead,
