Find out what nitrogen oxides (NOx) are, why they are a serious environmental concern, and what role they play in the Volkswagen diesel engine scandal.

Nevertheless, a high diversity of these bacteria may favor symbiosis with various legume species and maximize biological N fixation in similarly degraded areas. Therefore, the diversity of these ...

Alabama has scheduled an August execution with nitrogen gas for a man convicted three decades ago of shooting a woman in the head while she slept.

Catalytic fixation of molecular nitrogen by electrolytic and chemical reduction Eugene E. Van Tamelen and Douglas A. Seeley ...

Soybean nitrogen (N) demands can be supplied to a large extent via biological nitrogen fixation, but the mechanisms of source/sink regulating photosynthesis/nitrogen fixation in high yielding ...

SINCE 1940 I have not had the opportunity of reporting to English readers the results of our investigations on symbiotic nitrogen fixation. As an opportunity now offers itself, I will briefly ...

Nitrogen (N) equilibrium isotope fractionation (15α) involving gaseous, dissolved, and solid phases of ammonia (NH3) and ammonium (NH4+) (e.g., NH3(g)–NH3(aq)–NH4+(aq)–NH4+(s)) represents a ...

Nucleus detection is a fundamental task in histological image analysis and an important tool for many follow up analyses. It is known that sample preparation and scanning procedure of histological ...

The first neutral nitrogen molecule – other than dinitrogen – has been isolated and characterised by researchers in Germany. The molecule, the most energetic ever synthesised, is effectively stable at ...
