During combustion - one of the most popular industrial processes across all industry sectors - the chemical energy in fuels, such as natural gas, coal, or oil, is converted into heat by oxidization.

After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. For ...

As ice sheets melted during the deglaciation of the last ice age and global oceans warmed, oceanic oxygen levels decreased and "denitrification" accelerated by 30 to 120 percent, a new international ...

Denitrification is a microbial respiratory process in which oxidized nitrogen species, primarily nitrate (NO₃⁻) and nitrite (NO₂⁻), are sequentially reduced to gaseous forms such as nitric oxide (NO), ...
