Single superphosphate is currently one of the mostly used fertilizers as an alternative source for phosphorus and sulphur. Sulphur presents four stable isotopes (32S, 33S, 34S, and 36S) with natural abundances of 95.00; 0.76; 4.22; and 0.014% in atom

The so-called “enhanced-efficiency N fertilizers” were developed to mitigate ammonia losses from surface-applied urea (UR) and thereby increase N use efficiency and crop yield. However, research is needed to assess the efficiency of these product

The ion exchange chromatography technique in a cascade process was used to separate stable isotopes of nitrogen (14N/15N). For this purpose, three column systems (with different internal diameters, S1−14.5 cm; S2–9.5 cm; S3–5.2 cm) were used th

The aim of the study was to synthesize the urea (13CO(NH2)2), with 99% 13C atoms, and to perform a quality analysis for the diagnosis (breath test) of Helicobacter pylori. Furthermore, the process was submitted to economic analysis. The reaction was
