Abstract:
In situ experimentation in transmission electron microscopes (TEMs) has always been an exciting field of study. Over the years, improving the resolution of a TEM has been driving the research and development in this area, however, now that we have reached sub-angstrom resolution, the application of transmission electron microscope as a tool to study dynamic changes in a specimen is one of the major areas where the future interest lies. These dynamic changes could be induced either by heating, applying a bias, or by creating a reactive environment inside the TEM.Recently, with the advancements in microelectromechanical systems (MEMS) based technologies, the area of in situ TEM has progressed rapidly over the last decade.Here, we show the results from a few applications of our MEMS based heating system to investigate commonly studied materials in situ. During the demonstration on TITAN, we will show either the heat treatment of aluminium alloys or core-shell nanoparticles.
After the report, group DNL2002 will hold a Demo Show at 13:30, in the place of Energy Meeting Center-B6. Welcome all the interested fellows and students to attend!
