Atoms are made up of a nucleus, protons and electrons. Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be ...

This steel is nitrided after being shaped whereby obtaining a compound layer consisting of iron and nitrogen atoms of a thickness ranging from 5 to 50 micrometers. The steel can also contain 0.4% to 1.5% by weight of manganese.doi:US20090056835 A1Eric Chaduiron...
An alternative perspective to the proposed model is that iron rich nano-particles and nontronite dissolve in the intracellular acidic environment, leaving a residue of iron atoms at specific surface sites anchored to the windows of the zeolite channels. These sites may be active later as low ...
