INCORPORATING NITROGEN STABLE ISOTOPES INTO ATMOSPHERIC CHEMISTRY MODELS
2021The nitrogen stable isotope composition (δ15N) of nitrogen oxides (NOx) may be an effective tool to evaluate the accuracy of the NOx emission inventories, which are based on different assumptions. In order to approach this goal, the understanding of (1) the δ15N(NOx) values of the major emission sources, (2) how atmospheric processes, such as mixing ...

Stable nitrogen isotopes in Angola Basin surface sediments
Marine Geology, 1996Abstract Sedimentary δ15N contains a record of biogeochemical processes occurring in the water column. Stable nitrogen isotopes were measured in the bulk sedimentary matter of 18 surface sediment samples collected in three transects in the eastern Angola Basin, perpendicular to the coast, at 6 °S, 12 °S and 17 °S and two samples from the Zaire ...

Metabolic Labeling of Microorganisms with Stable Heavy Nitrogen Isotopes (15N)
2018Quantitative Proteomics based on stable isotope labeling by 15N is a versatile method in determination of changes in microbial protein expression profiles. Once set up, the workflow relies on defined chemical or commercially available complex media leading to universal heavy labeling by the stable isotope 15N.

Carbon, Nitrogen and Oxygen Stable Isotope Ratios in Chitin
2010Stable isotope ratios in chitin are firmly imprinted during biopolymer biosynthesis and reflect dietary, metabolic, and environmental influences. Chitin is a chemically complex amino sugar biopolymer that also includes non-amino-sugar moieties with contrasting isotopic compositions.

Stable nitrogen isotopic composition of wine: a preliminary investigation
2013The 15N/14N ratio has been measured in several foods to trace geographical origin and agricultural systems, but not yet in wine. In this work we developed a method for measuring 15N/14N in bulk wine, following dealcoholisation and dehydration. The δ15N of wine did not change after freeze-drying the sample or evaporating it under vacuum, obtaining ...
