Nitrogen isotope analysis of ammonium and glycine [PDF]
, 2005 Stable isotope techniques can be used as a tool in nitrogen cycling studies of different ecosystems. The studies are based on measurement of the heavy (15N)- to- light (14N) isotopic ratios of nitrogen in different biospheric pools.

The effectiveness of using carbonate isotope measurements of body tissues to infer diet in human evolution: Evidence from wild western chimpanzees (Pan troglodytes verus)* [PDF]
, 2015 Changes in diet throughout hominin evolution have been linked with important evolutionary changes. Stable carbon isotope analysis of inorganic apatite carbonate is the main isotopic method used to reconstruct fossil hominin diets; to test its ...

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production
Advanced Functional Materials, EarlyView.Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Stable Isotope Compositions of Wild and Farmed S. Paramoamosion and its Implication for Tracebility
Journal of Isotopes, 2014 To evaluate the possibility of using stable isotopes for discriminating wild and farmed mangrove crabs, Stable carbon and nitrogen isotope ratios of Scylla paramamosion tissues were analyzed. The carbon and nitrogen isotope ratios of wild S. paramamosion

Neutrino fluence after r-process freeze-out and abundances of Te isotopes in presolar diamonds [PDF]
, 1998 Using the data of Richter et al. (1998) on Te isotopes in diamond grains from a meteorite, we derive bounds on the neutrino fluence and the decay timescale of the neutrino flux relevant for the supernova r-process. Our new bound on the neutrino fluence F

Stable carbon isotopes in archaeobotanical remains and palaeoclimate.
Contributions to Science, 2008 Es descriu una metodologia recent per a inferir la precipitació en el passat basada en l’anàlisi de la composició isotòpica del carboni (δ13C) en restes arqueobotàniques. Un cop descrita la base fisiològica de la tècnica, s’il·lustra l’aplicabilitat de δ13C mitjançant un exemple referent al NE peninsular.
