Amine exchange into ammonium bisulfate and ammonium nitrate nuclei [PDF]
Abstract. The exchange kinetics and thermodynamics of amines for ammonia in small (1–2 nm diameter) ammonium bisulfate and ammonium nitrate clusters were investigated using electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). Ammonium salt clusters were reacted with amine gas at constant pressure to determine

Anthocyanin Production through Callus Culture of Apple: Effect of Nitrogen Source and Concentration of Magnesium [PDF]
Anthocyanins have attracted a great deal of attention due to their capability in protecting humans from chronic diseases. Production of natural anthocyanins from fresh plant material has many limitations. Therefore, the use of plant biotechnology for the

Ammonium oxathioamidate (1) was synthesised by the reaction between O-ethyl-thioxamate (oxalic acid-1-amide-2-O-ethyl ester) and ammonium hydrogen carbonate in water solution. Compound 1 was fully characterised by both microanalytical (elemental analysis, melting point determination) and spectroscopic means (FT-IR and NMR spectroscopy).

Function and Regulation of Ammonium Transporters in Plants
Ammonium transporter (AMT)-mediated acquisition of ammonium nitrogen from soils is essential for the nitrogen demand of plants, especially for those plants growing in flooded or acidic soils where ammonium is dominant.

Ammonium Does Not Induce Ammonium Absorption in Tomatoes [PDF]
We examined root ammonium absorption by tomato seedlings (Lycopersicon esculentum Mill. `T-5') after first exposure of the roots to ammonium. Some plants received a nutrient medium containing nitrate as the sole N source. In a second treatment, the leaves were sprayed daily with a urea solution, while the roots were in N-free medium.
