Ammonium benzenephosphonate [PDF]
In the crystal structure of the title salt, NH(4) (+).[(C(6)H(5))P(O)(2)(OH)](-) or NH(4) (+)·C(6)H(6)O(3)P(-), the N and O atoms inter-act via hydrogen bonds to generate a layer motif. The phenyl rings are stacked above and below this layer, sandwiching the hydrogen-bonded layer.

Effect of a Profound Feedstock Change on the Structure and Performance of Biogas Microbiomes
In this study the response of biogas-producing microbiomes to a profound feedstock change was investigated. The microbiomes were adapted to the digestion of either 100% sugar beet, maize silage, or of the silages with elevated amounts of total ammonium ...

Ammonium Toxicity in Bacteria [PDF]
Although an excellent nitrogen source for most bacteria, ammonium was-in analogy to plant and animal systems-assumed be detrimental to bacteria when present in high concentrations. In this study, we examined the effect of molar ammonium concentrations on different model bacteria, namely, Corynebacterium glutamicum, Escherichia coli, and Bacillus ...

DENSITIES OF AMMONIUM FLUORIDE-AMMONIUM NITRATE-AMMONIUM HEXAFLUOZIRCONATE SOLUTIONS [PDF]
The densities of various Zirflex-type solutions at 25 gas-cooled C can be expressed by the equation: p calc = (0.99710 + 0.03l57 m) + (0.02046 - 0.002659 m)c -(0.0033460.000703 m)c3/2 + 0.14349x + 0.49z where m = moles liter/ sup -1/ NH/sub 4/NO/sub 3/, c = moles liter/sup -1/ NH/sub 4/F, x = moles liter/ sup -1/ (NH/sub 4/)/sub 2/ZrF/sub 6/, and z ...

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.
