Question: Graphine is strong because it has a lattice structure like diamonds. Are there any other strong elements or compounds where the atoms are arranged in this way?

Graphene and diamond are different arrangements of carbon atoms – you can see them here: http://rimg.geoscienceworld.org/content/75/1/47/F1.large.jpg
Diamond and sand are very similar. Sand is made up of silicon dioxide and silicon sits just below carbon in the periodic table so they have very similar characteristics.
You can see a picture of diamond: http://www.chemguide.co.uk/atoms/structures/diamond.GIF
and silicon dioxide:
Scientists here http://www.kurzweilai.net/a-new-self-assembling-graphene-like-material-for-flat-semiconductors have made a material that looks a bit like graphene, in that it’s made up of hexagonal sheets, but it’s probably not very strong – it’s quite similar to the materials that I work with. The bonds to the nickel (the green spheres) will definitely not be as strong!
