Time will tell whether these findings are relevant to how dinitrogen is reduced to ammonia in nature on a huge scale by nitrogenase enzymes. ❋ Unknown (2006)
I became interested in dinitrogen chemistry around 1980, and polymer chemistry (first ring-opening metathesis polymerization and later olefin and acetylene polymerization) a few years after that. ❋ Unknown (2006)
These creatures, now called anammox bacteria, transform caustic and hazardous ammonium into dinitrogen, the harmless nitrogen gas that makes up 78% of the air we breathe. ❋ Unknown (2010)
With support of the NIH I also was able to achieve in 2003 a long sought goal for hundreds of researchers over a period of 40 years, the catalytic reduction of dinitrogen with protons and electrons at room temperature and pressure. ❋ Unknown (2006)
If you compress NO2, you wind up with the dimmer N2O4, dinitrogen tetroxide, which dissociates back to NO2 on pressure release, producing toxic levels of NO2. ❋ James Killus (2007)
He suggested that dinitrogen monoxide, popularly known as "laughing gas" and formed through microbiological processes in the ground, could have the same effect. ❋ Unknown (1997)
The most important aspect of tropical legumes is their ability to fix P in association with rhizobium atmospheric dinitrogen which becomes available to subsequent crops in rotational cropping systems. ❋ Unknown (1992)
The spacecraft's mass at launch was some 13 tonnes, most of which was the propellants unsymmetrical dimethylhydrazine (UDMH) and dinitrogen tetroxide (DTO). ❋ Unknown (2011)
Titan II also used storable propellants, Aerozine 50 and dinitrogen tetroxide. ❋ Unknown (2010)
Carbon dioxide effects on heterotrophic dinitrogen fixation in a temperate pine forest. ❋ Unknown (2010)

His interests include the inorganic and organometallic chemistry of high oxidation state early metal complexes, catalytic reactions and mechanisms of reactions involving alkylidene complexes, especially olefin metathesis reactions, the chemistry of high oxidation state dinitrogen and related complexes, and the controlled synthesis of polymers prepared using well-defined organometallic initiators. ❋ Unknown (2010)
So, once the Haber-Bosch process established it could be done, chemists across the world began to burn a lot of natural gas to get dinitrogen to react with hydrogen. ❋ Unknown (2010)
This dinitrogen will react with oxygen and rain to Earth, where various microbes "fix" it - separate the twins, making them available to bond with other molecules, such as carbon. ❋ Unknown (2009)
In addition to broadening the field of dinitrogen chemistry, the work adds to efforts to develop reactions that could be used in fertilizer-making processes-methods that are milder than the ubiquitous Haber-Bosch method, which reduces N ❋ Unknown (2009)
To determine that the archaea were indeed fixing nitrogen, the researchers first incubated the archaeal-bacterial assemblages with a dinitrogen gas, N ❋ Unknown (2009)
From the periodic table find the molar mass of dinitrogen pentoxide: ❋ Unknown (2009)
The scientists started with a complex of the metal hafnium and dinitrogen in solution and then added carbon monoxide gas. ❋ Unknown (2009)
