Nitrogen — chemically bound as dinitrogen gas — is the most abundant element in the atmosphere. (sciencedaily.com)
Rainer Zah at the Swiss Materials Science and Technology research institution faults current estimates for not taking into account the global warming effects of dinitrogen oxide, a very potent GHG produced during the cultivation of switchgrass. (treehugger.com)
This conversion, known as the Haber - Bosch process, combines dinitrogen molecules from the air with dihydrogen molecules. (sciencemag.org)
