Uptake of ammonium ions by marine microorganisms called archaea is a key first step in the conversion of ammonium to nitrogen found in ecosystems. Structural evidence reveals how archaea capture ...

Ferrocene is a key molecule for developing molecular machines. However, it readily decomposes on the surface of flat noble metal substrates, marking a significant challenge. Now researchers have ...

(top) Proportion of copper (I) in copper oxide and copper (0) in metallic copper particles under different applied voltages. A more negative voltage correlates with the appearance of more Cu-Cu bonds.

Although the known photometric techniques for the calculation of ammonia are accurate, they take up a substantial amount of time (Nessler technique 30 min, indophenol technique 90 min reaction time).

The most preferred form of energy storage is metal-ion batteries, like lithium-ion batteries. Because of their great energy density and adaptability, they dominate the markets for portable consumer ...

Researchers at KAUST in Saudi Arabia are exploring how ammonium-ion electrolytes could help create eco-friendly metal-free batteries for grid storage. Rechargeable batteries that use ammonium cations ...
