The pigment Prussian blue consists of iron cations, cyanide anions, and water. The empirical formula—minus the water of crystallization—is Fe 7 (CN) 18. This seems odd with respect to the iron ...

A team of researchers from the Astrobiology Centre (INTA-CSIC) has shown that hydrogen cyanide, urea and other substances considered essential to the formation of the most basic biological molecules ...

Prussian blue analogues (PBAs) have emerged as a promising class of materials for sodium‐ion battery electrodes. Their distinctive open framework, which comprises mixed‐metal hexacyanoferrates, ...

For the first time in more than three centuries, Prussian Blue – long confined to its rigid cubic shape – has been transformed into an octahedral structure. A research team led by Prof. Changshin Jo ...

Plastic waste breaks down over time into nanoplastics (<0.1 μm). Microplastics smaller than 20 μm cannot be removed in currently operating water treatment plants and must be agglomerated to a larger ...
