Discovery of face-centered-cubic ruthenium nanoparticles: facile size-controlled synthesis using the chemical reduction method
We report the first discovery of pure face-centered-cubic (fcc) Ru nanoparticles. Although the
fcc structure does not exist in the bulk Ru phase diagram, fcc Ru was obtained at room …

The ubiquity of iron
PA Frey, GH Reed - 2012 - ACS Publications
The importance of iron in living systems can be traced to the many complexes within which it
is found, to its chemical mobility in undergoing oxidation–reduction reactions, and to the …
