Nitrogen is one of the primary ... Additionally, aerobic ammonia oxidizers are also autotrophs, fixing carbon dioxide to produce organic carbon, much like photosynthetic organisms, but using ...

On top of the primary particle output, emissions of precursor gases (including sulphur dioxide, nitrogen oxides, volatile organic compounds and ammonia) lead to the generation of secondary aerosol ...

But ammonia, the molecule NH3, is made up only of nitrogen and hydrogen. There’s no carbon in the formula, so where do the carbon emissions come from? The standard way of producing the needed hydrogen ...

By exposing synthetic iron-rich minerals to nitrogen-laced water, they triggered a chemical reaction that oxidized the rock and produced ammonia. Dubbed “geological ammonia,” the process emitted no ...

Samples returned from an asteroid contain a surprising abundance of the basic ingredients of life. They were discovered to be ...
