Molecules form 2-D patterns never before observed

Description (Technische Universitaet Muenchen) Tessellation patterns that have fascinated mathematicians since Kepler worked out their systematics 400 years ago -- and that more recently have caught the eye of artists and crystallographers -- can now be seen in the laboratory. They first took shape on a surface more perfectly two-dimensional than any sheet of paper, a single layer of atoms and molecules atop an atomically smooth substrate. Physicists coaxed these so-called Kepler tilings "onto the page" through guided self-assembly of nanostructures.
