Direct synthesis of cyanate anion from dinitrogen catalysed by molybdenum complexes bearing pincer-type ligand

Nature Communications, 2022
Direct conversion of dinitrogen to organonitrogen compounds is a challenging goal in nitrogen fixation chemistry. Here, the authors report the catalytic formation of cyanate anion from dinitrogen under ambient conditions using a molybdenum complex.

Atmospheric Nitrogen Fixation via a Porous Coordination Polymer Platform with Bridging Dinitrogen Anions [PDF]

, 2021
The design of highly electron-active and stable heterogeneous catalysts for ambient nitrogen reduction reaction is challenging due to the inertness of N2 molecule.

Localized osmotic stress activates systemic responses to N limitation in Medicago truncatula–Sinorhizobium symbiotic plants

Frontiers in Plant Science, 2023
In mature symbiotic root nodules, differentiated rhizobia fix atmospheric dinitrogen and provide ammonium to fulfill the plant nitrogen (N) demand. The plant enables this process by providing photosynthates to the nodules.

Some aspect of the logical way of studying dinitrogen fixation in an agroforestry context for improving food production [PDF]

, 2001
Dinitrogen fixation in an agroforestry context requires a careful approach which initially require derivation of the methods to be used and careful selection of the priorities of factors which influence the process.

DRIVERS OF THE DYNAMICS OF DIAZOTROPHS AND DENITRIFIERS IN NORTH SEA BOTTOM WATERS AND SEDIMENTS

Frontiers in Microbiology, 2015
The fixation of dinitrogen (N2) and denitrification are two opposite processes in the nitrogen cycle. The former transfers atmospheric dinitrogen gas into bound nitrogen in the biosphere, while the latter returns this bound nitrogen back to atmospheric ...

Ammonia Formation Catalyzed by Dinitrogen-Bridged Dirhenium Complex Bearing PNP-Pincer Ligands under Mild Reaction Conditions [PDF]

, 2020
A series of rhenium complexes bearing a pyridine-based PNP-type pincer ligand are synthesized from rhenium phosphine complexes as precursors. A dinitrogen-bridged dirhenium complex bearing the PNP-type pincer ligands catalytically converts dinitrogen ...

Possible association of diazotrophs with marine zooplankton in the Pacific Ocean

MicrobiologyOpen, 2016
Dinitrogen fixation, the biological reduction in N2 gas to ammonia contributes to the supply of new nitrogen in the surface ocean. To understand the diversity and abundance of potentially diazotrophic (N2 fixing) microorganisms associated with marine ...

Relative abundance of nitrogen cycling microbes in coral holobionts reflects environmental nitrate availability

Royal Society Open Science, 2021
Recent research suggests that nitrogen (N) cycling microbes are important for coral holobiont functioning. In particular, coral holobionts may acquire bioavailable N via prokaryotic dinitrogen (N2) fixation or remove excess N via denitrification activity.
