Scientists at the University of Birmingham have developed a method to visualise gold on the nanoscale by using a special probe beam to image 20 atoms of gold bound together to make a cluster. The research is published today in the Royal Society of Chemistry’s journal Nanoscale.
Physicists have theorised for many years how atoms of gold and other elements would be arranged and ten years ago the structure of a 20-atom tetrahedral pyramid was proposed by scientists in the US. Birmingham physicists can now reveal this atomic arrangement for the first time by imaging the cluster with an electron microscope. Via A cluster of twenty atoms of gold visualized for the first time.
