Nano Gold


Credit: Fritz Haber Institute of the Max Planck Society

Giza in the Nanoworld: Gold particles were arranged on virtual desert sand. 7 gold atoms form a triangle of 6 atoms with one additional gold atom attached. The cluster of 20 atoms are piled together to form a pyramid with four equivalent corners and faces; a tetrahedron. The cluster, with one atom less, can be constructed by cutting a corner atom off the tetrahedron.

It turns out that gold has other qualities than being just pretty. Gold seems to assist certain chemical reactions and are currently being considered as catalysts.
