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)
