Spectroscopic Identification of the Dinitrogen Fixation and Activation by Metal Carbide Cluster Anions PtC_n^– (n = 4–6)

, 2022
Nitrogen fixation is confronted with great challenges in the field of chemistry. Herein, we report that single metal carbides PtCn– and PtCnN2– (n = 4–6) are indispensable intermediates in the process of nitrogen fixation by mass spectrometry coupled ...

N2 cleavage by silylene and formation of H2Si(μ-N)2SiH2

Nature Communications
Fixation and functionalisation of N2 by main-group elements has remained scarce. Herein, we report a fixation and cleavage of the N ≡ N triple bond achieved in a dinitrogen (N2) matrix by the reaction of hydrogen and laser-ablated silicon atoms. The four-

Remarkable catalytic activity of dinitrogen-bridged dimolybdenum complexes bearing NHC-based PCP-pincer ligands toward nitrogen fixation

, 2017
Intensive efforts for the transformation of dinitrogen using transition metal–dinitrogen complexes as catalysts under mild reaction conditions have been made. However, limited systems have succeeded in the catalytic formation of ammonia.

DiNitrogen Fixation and Nitrogen Transfer in Temperate Legume-Grass Communities [PDF]

Perennial forage legumes fix atmospheric dinitrogen (N2) and, in mixed swards of legumes and grasses, may transfer nitrogen (N) to the companion grass (Brophy et al., 1987; Ta and Faris, 1987).

Evidence for efficient regenerated production and dinitrogen fixation in nitrogen-deficient waters of the South Pacific Ocean: impact on new and export production estimates [PDF]

Biogeosciences, 2008
One of the major objectives of the BIOSOPE cruise, carried out on the R/V Atalante from October-November 2004 in the South Pacific Ocean, was to establish productivity rates along a zonal section traversing the oligotrophic South Pacific Gyre (SPG ...

Divergent Capacity of Scleractinian and Soft Corals to Assimilate and Transfer Diazotrophically Derived Nitrogen to the Reef Environment

Frontiers in Microbiology, 2019
Corals are associated with dinitrogen (N2)-fixing bacteria that potentially represent an additional nitrogen (N) source for the coral holobiont in oligotrophic reef environments.

Low rates of dinitrogen fixation in the eastern tropical South Pacific

, 2019
Recent work has suggested that the oxygen deficient zone (ODZ) and overlying surface waters of the eastern tropical South Pacific (ETSP) is a potential niche for dinitrogen (N2) fixation.

Five decades of N2 fixation research in the North Atlantic Ocean

Frontiers in Marine Science, 2015
Dinitrogen (N2) fixation (the reduction of atmospheric N2 to ammonium by specialized prokaryotic microbes), represents an important input of fixed nitrogen and contributes significantly to primary productivity in the oceans.
