Gold clusters (IMAGE) University of Jyväskylä - Jyväskylän yliopisto Caption Electron microscopy image (background) of an ordered crystal consisting of 25-atom gold clusters. The data could be interpreted by a model of tightly packed polymeric chains of the clusters (light spheres). A close-up visualization of two such clusters, connected by a gold-ligand chain is shown in front.
