In Situ Electron Microscopy
Materials for Energy Efficient ICT
The in-situ electron microscopy package comprises two dedicated TEM holders, a fast camera designed for in-situ experiments and a holder storage unit where holders may be kept under vacuum.
- Protochips Poseidon continuous flow liquid cell in-situ holder with additional electrochemical cell.
- Gatan double tilt vacuum transfer holder Model 648 that enables air-sensitive samples to be transferred to the electron microscope without the sample being exposed to the atmosphere in order to study air-sensitive samples.
- Gatan OneView Camera Model that enables TEM images to be acquired at high frame rates (up to 300 fps). High-quality video can be recorded over a range of resolution and speed combinations, from 4096 x 4096 pixels at 25 fps, to 512 x 512 pixels at 300 fps. The camera is supplied with a dedicated PC incorporating a ‘LookBack’ streaming video function to post-event trigger video capture; it is possible to keep a rolling capture up to 20s in length to avoid missed reaction events.
- Gatan turbo pumping station Model 655 designed for storing the TEM holders under vacuum when not being used.
Using the holder the sample can be examined as part of a continuous flow experiment. Or, by using a static cell with electrical contacts, it is possible to image structural changes during electrochemical reactions. This package is ideal for in-situ studies of reactions, phase transformations and domain wall movement.
