The anisotropic growth of a Pt-rich phase along the 〈111〉 and 〈200〉 directions at the initial growth stage results in Pt segregation to the 14 axes of a rhombic dodecahedron, forming a ...

So Bell opted to engrave his calendar on a rhombic-dodecahedron, which comprises 12 four-sided, diamond-shaped faces. “It is such a complicated shape,” Bell says of the final, tilted arrangement.

Can the shape of a crystal really change how well it performs in clean energy technology? A new study says yes—decisively. Researchers from National Taiwan University, National Tsing Hua ...

Technically, the shape is a rhombic dodecahedron with a hexagon for a base; the geometry was specially designed by Orgusaar to create a space that was easily assembled out of identical elements.
