TL;DR: In this article, Nitrosomonas europaea from continuous pure cultures was incubated with 26.4 μ M NH 3 (= 0.37 mg NH 3 -N l −1 ) at various NH 4 + concentrations, pH values and temperatures.

TL;DR: The results showed that the mordenite exhibited higher overall uptake concentrations at equilibrium compared with clinoptilolite at solution concentrations greater than 80 mg/l, which was rather an unexpected result since the majority of other work shows clinoptILolite exhibiting a higher affinity for potassium ion compared with ammonium ion.

TL;DR: In this article, a field experiment was carried out on a sunflower crop in spring 2006 with the aim of evaluating the effect of the N -( n -butyl) thiophosphoric triamide (NBPT) in the mitigation of volatilized NH 3 from a urea-fertilised soil.

TL;DR: A study of hydrogen and ammonia release from the series of reactant mixtures (LiNH2)x(LiBH4)1-x, where x=0.667 corresponds to the composition LiB0.33N0.67H2.67 having a theoretical hydrogen content of 11.9 wt %.
Abstract: We recently reported the synthesis of a new quaternary hydride in the lithium−boron−nitrogen−hydrogen quaternary phase diagram with the approximate composition LiB0.33N0.67H2.67 having a theoretical hydrogen content of 11.9 wt %. This new compound forms by the reaction of appropriate amounts of lithium amide (LiNH2) and lithium borohydride (LiBH4) and releases greater than 10 wt % hydrogen when heated. A small amount of ammonia, 2−3 mol % of the generated gas, is also released. We now report a study of hydrogen and ammonia release from the series of reactant mixtures (LiNH2)x(LiBH4)1-x, where x = 0.667 corresponds to the composition LiB0.33N0.67H2.67. We measured hydrogen and ammonia release amounts as a function of composition and found that maximum hydrogen and minimum ammonia release do occur for x = 0.667. We also present evidence for an additional new quaternary phase and for two possibly metastable phases in this system.
