THE TORSIONAL VIBRATIONS OF THE AMMONIUM IONS IN AMMONIUM IODIDE AND AMMONIUM BROMIDE [PDF]
Abstract The far-infrared spectra of NH4I and NH4Br have been measured at temperatures of −223 to −53 °C. The torsional vibrations of the NH4+ ions in the phase III crystalline salts were observed at 301 cm−1 for NH4I at −223 °C and at 348 cm−1 for NH4Br at −166 °C.

Repurposing Quaternary Ammonium Compounds as Potential Treatments for COVID-19
The COVID-19 pandemic has highlighted an important role for drug repurposing. Quaternary ammonium compounds such as ammonium chloride, cetylpyridinium and miramistin represent widely accessible antiseptic molecules with well-known broad-spectrum ...

Increasing Hydrogen Density with the Cation-Anion Pair BH4−-NH4+ in Perovskite-Type NH4Ca(BH4)3
A novel metal borohydride ammonia-borane complex Ca(BH4)2·NH3BH3 is characterized as the decomposition product of the recently reported perovskite-type metal borohydride NH4Ca(BH4)3, suggesting that ammonium-based metal borohydrides release hydrogen gas ...

Ammonium perchlorate and ammonium perchlorate-binder sandwich combustion [PDF]
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

Ammonium and methyl ammonium transport by RhAG
The erythroid Rh protein (RhAG) is one component of the “Rh complex” that is known for its immunogenic characteristics. Recently, a role of RhAG in transport of ions has been proposed. In this study, we characterized NH3/NH4+ transport by RhAG expressed in Xenopus oocytes. To do so we used ion‐selective microelectrodes & two‐electrode voltage clamp
