The nitrogen cycle is a critical component of Earth's ecosystem, playing an essential role in sustaining life. However, human activity has significantly disrupted the natural balance of the nitrogen ...

Wheat, millet and maize all need nitrogen to grow. Fertilisers therefore contain large amounts of nitrogenous compounds, which are usually synthesised by converting nitrogen to ammonia in the ...

The anion-exchange membrane reactor hydrogenates pyridine to piperidine. Credit: Yokohama National University Successful reduction of the chemical manufacturing industry's environmental impact relies ...

FURTHER to our earlier communications concerning the excretion of nitrogen compounds from the nodules of leguminous species, I wish to add the following: a distinct excretion occurs only in media ...

One of the chemicals considered essential to life on Earth may have originated in outer space, researchers have found. Nitrogen compounds, including ammonium salts, may have made their way to Earth ...

Tackling pollution from the emission of nitrogen compounds, particularly ammonia, could reduce many of the 23.3 million years of life that were lost prematurely across the world in 2013 due to ...

Nitrogen is abundantly available in nature and forms the basis for many valuable products, both natural and artificial. This requires a reaction known as "nitrogen fixation," whereby molecular ...

Nitrogen metabolism of gut bacteria can provide health benefits. Specifically, gut microbes metabolize dietary nitrates and nitrites and prevent the formation of cancer-causing compounds called ...

SAE International Journal of Engines, Vol. 7, No. 4 (October 2014), pp. 1961-1983 (23 pages) ABSTRACT The tailpipe exhaust emissions were measured using a EURO4 emissions compliant SI car equipped ...

Chemists have developed a boron-based molecule capable of binding nitrogen without assistance from a transition metal. This might be the first step towards the energy-saving production of fertilizers.
