Birth of a crystal filmed in atomic resolution (Gold)
From Faith Pring
The exact moment a crystal is formed from a previously scattered group of atoms has been captured on video in real time in a world-first experiment by experts in nanotechnology.
The scientists, led by the University of Nottingham School of Chemistry’s Professor Andrei Khlobystov and Professor Ute Kaiser, head of the Electron Microscopy of Materials Science in the University of Ulm, have used carbon nanotubes – atomically thin hollow cylinders of carbon just 1-2 nanometers wide – as miniature test tubes for atoms and molecules to record moving images at the atomic scale using transmission electron microscopy (TEM).
This video shows an amorphous particle of Au irradiated with the electron beam, providing enough energy for nucleation.
