Discovery of Gold Nanocluster “Double” Hints at Other Shape Changing Particles

****EMBARGOED UNTIL JUNE 14, 5AM EST*** New Analysis Approach Brings Two Unique Atomic Structures into Focus Setting out to confirm the predicted structure of Gold-144, researchers discovered an entirely unexpected atomic arrangement (right). The two structures, described in detail for the first time, each have 144 gold atoms, but are uniquely shaped, suggesting they also behave differently. (Courtesy of Kirsten Ørnsbjerg Jensen) Chemically the same, graphite and diamonds are as physically distinct as two minerals can be, one opaque and soft, the other translucent and hard. What makes them unique is their differing arrangement of carbon atoms. Polymorphs, or materials with the same composition but different structures, are common in bulk materials,and now a new study in Nature Communications confirms they exist in nanomaterials, too. Researchers describe two unique structures for the…
