Sentence examples for shift of nitrogen from inspiring English sources

With the shift of nitrogen cycling in forest ecosystems from organic to inorganic form, recent studies have shown that N can be lost from temperate forest ecosystems predominantly by the way of DON (Hedin et al. 1995; Perakis and Hedin 2002).

Electrochemical characterization at a rotating disk electrode in O2-saturated 0.1 M HClO4 revealed a superior catalytic activity for ORR, in terms of E1/2 and mass activity, in those catalysts showing higher PtN interaction, expressed as binding energy shift of nitrogen components.

Using the 15N NMR chemical shifts of nitrogen atoms in nitramino groups of cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (bicyclo-HMX or BCHMX) and additional 10 nitramines, we have assessed its reactivity in detonation, under the influence of impact, and by action of electric spark.
