           Characterization of nano-structure materials
      With the help of TEM, we are able to build the lab inside of the microscopes, including TECNAI G2 20 and TITAN. By identifying the atom scale structure, we focus on the properties of the materials.
      What's more important is that in-situ experiments can be done in the TEM. We add electron irradiation, high specimen temperatures and imaging/ manipulation of nanotubes to our experiments.
