ENVIRONMENTAL SPHERICAL ABERRATION CORRECTION TRANSMISSION ELECTRON MICROSCOPE

The environmental spherical aberration-corrected transmission electron microscope    can simulate the working conditions of the material under a certain gas environment    and characterize the dynamic behavior of the microstructure. Gases currently available    include, but are not limited to, hydrogen, oxygen, carbon dioxide, argon and nitrogen.    In addition, through specially designed sample holder, the material's response to    specific conditions such as liquid, pressure, electrical stimulation, heating, cooling,    etc. can be observed in real time. The TEM is also equipped with a spherical aberration    corrector that achieves very high spatial resolution (0.1 nm). This TEM can operate with    acceleration voltages of 80,200 and 300 kV.
