Nitrogen can be a limiting macronutrient for carbon uptake by the marine biosphere. The process of denitrification (conversion of nitrate to gaseous compounds, including N 2 (nitrogen gas)) removes ...

Centuro A-PRO is a more concentrated formulation of the original Centuro, containing a higher concentration of the active ...

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 ...

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.

(a) Illustration of glucose metabolism. FADH 2: flavin adenine dinucleotide (reduced form), FAD: flavin adenine dinucleotide, ATP: adenosine triphosphate, ADP: adenosine diphosphate; (b, c) KEGG ...

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), ...

In the new cycle of AMPs in the UK, the Environment Agency (EA) is starting to impose total nitrogen limits in accordance with the European Urban Wastewater Directive for nutrient sensitive zones.

A new study has revealed how tiny microbes in rivers and wetlands across China help clean up excess nitrogen pollution, offering fresh insights into the health of freshwater ecosystems and the global ...

The U.S. clean coal technology market was valued at USD 0.84 billion in 2025 and is expected to grow at a CAGR of 7.83% from 2026 to 2035, reaching USD 1.79 billion. Growth is driven by stricter ...
