image: A semi-infinite crystal of aluminum with a [110]-truncated facet (bottom left), a [111]-truncated facet (bottom right) and a [001]-truncated facet (top). The atoms are grey and the zero-bonding density surface is drawn in blue. Increasing bonding density is indicated by increasingly bright colors. This image relates to an article that appeared in the March 25, 2011, issue of Science, published by AAAS. The study, by Dr. Philip Nakashima, at Monash University in Clayton, VIC, Australia, and colleagues was titled, "The Bonding Electron Density in Aluminum." view more
