The term greenhouse gas often brings carbon dioxide (CO2) to mind, and rightly so, as it is a key contributor to rising ...

Some bacteria and archaea make nitrous oxide during ammonia oxidation to nitrite in well-oxygenated waters, whereas denitrifying bacteria produce it during reduction of nitrate in oxygen-poor waters.

Approximately 15 people living near the hospital have reportedly contracted jaundice, with water contamination linked to high levels of ammonia and coliform bacteria suspected as the cause.

In this review, we have discussed the principles of electrocatalytic water oxidation reaction (WOR), the electrocatalyst and electrode design strategies for the most efficient results, and recent ...

In the organocatalytic Diels–Alder (DA) reactions, a simple amine is used as a catalyst to form an iminium adduct as an electron-withdrawing group that speeds up reaction with the diene.

Mar. 26, 2025 — Researchers have developed a molecular system for controlled release of iron. They integrated ferrocene, a molecular sandwich that encloses an iron atom, with a carbon 'nanohoop ...

Once hydrogen is separated and recovered, it can be combined with various catalytic reactions to synthesize useful and easy-to-handle chemicals and fuels (e.g., CO 2 to methane, nitrogen to ammonia, ...
