Some examples of environmental experiments under gas and temperature conditions in the Ly-EtTEM microscope

ATOMIC PACMAN
A silver nanoparticle deposited on a carbon supporting film is observed at 300 kV under an oxygen pressure of 0.6 mbar at 495°C. O₂ molecules dissociated at the surface of the Ag NP and further reacts with the carbon film to produce volatile CO₂: the supporting film is thus consumed and the NP runs on it to maintain the contact. Short sequence of about 2', low res.; (c) Ly-EtTEM team, (2013).
Note: the video sequences should run at a 10 frames-per-seconds speed in nominal conditions (fluent internet traffic)
