they all have a similar enzyme complex called nitrogenase that catalyzes the reduction of N 2 to NH 3 (ammonia), which can be used as a genetic marker to identify the potential for nitrogen fixation.

Although N 2 surrounds us, comprising 78% of our atmosphere, it presents both kinetic and thermodynamic obstacles for developing reaction chemistry. In nature, nitrogen is reduced by nitrogenase ...

BRUSSELS — The Netherlands is rolling back its nitrogen reduction targets, setting the stage for a showdown with its own ...

A major drawback is the cost of production, dominated by the quantity of an expensive platinum catalyst required for the oxygen reduction reaction. Recent research indicates promising replacement ...

In addition, any unreacted nitrogen and hydrogen are recycled. The reaction is reversible. In a chemical equation, the symbol ⇌ is used instead of an ordinary arrow if the reaction is reversible ...

Electrocatalytic nitric oxide reduction reaction (NORR) offers a promising route for sustainable ammonia (NH 3) synthesis and ...

THE ENVIRONMENTAL WATCHDOG said there was a “welcome reduction” in nitrogen levels in rivers last year – although levels were still too high in the dairy farming heartland of the south-east.
