Controlling The Atomic Structure of Size-Selected Gold Nanoparticles
Wednesday 28 May 2014

Controlling the size of nanoparticles is not enough. Even size-selected clusters come in different flavours – they show different atomic arrangements. Now Simon Plant and Lu Cao have demonstrated a new level of mastery over the proportions of the different atomic structures of Au923 clusters. By careful control of the cluster source parameters they were able to eliminate the icosahedra. The work is published in JACS and highlighted in Spotlight. Of course it also prompts the next challenge - to prepare pure samples of single isomers, which would allow catalytic behavior to be studied for a set cluster size as a function of the atomic arrangement…onwards and upwards!
