From logo to Letter
Monday 12 December 2011

The STEM image of a magic-number gold cluster (Au923) chosen by the IoP’s Electron Microscopy and Analysis Group as the logo of their national meeting in September 2011 (EMAG) has now made its appearance in the scientific literature (Wang & Palmer, Nano Letters, 2011,DOI). While the logo was no doubt chosen as much for its artistic merits as the science it discloses, the Nano Letter focuses on quantitative observations (including mass spectrometry and dynamical imaging) of gold adatoms and groups found to exist on top of the microfacets of the cluster itself, a new window on the nanoworld made possible by the aberration-corrected STEM, and possibly relevant to a number of catalytic processes.
