Direct TEM observation of phase separation and crystallization in Cu45Zr45Ag10 metallic glass
The structural evolution of Cu45Zr45Ag10 metallic glass was investigated by in situ transmission electron microscopy heating experiments. The relationship between phase separation and crystallization was elucidated. Nucleation and growth-controlle ...

In situ environmental TEM studies using MEMS based devices

In situ TEM study on redox of Pd nanoparticles

Controllable Atomic Scale Patterning of Freestanding Monolayer Graphene at Elevated Temperature
We show that by operating a scanning transmission electron microscope (STEM) with a 0.1 nm 300 kV electron beam, one can sculpt free-standing monolayer graphene with close-to-atomic precision at 600 degrees C. The same electron beam that is used for destructive sculpting can be u ...

Quasi in situ analytical TEM to investigate electrochemically induced microstructural changes in alloys: AA2024-T3 as an example
A quasi in situ method using a specially developed holder is presented to follow electrochemically induced microstructural changes on a nanometre scale using analytical transmission electron microscopy (TEM). By following a specific specimen area after repeated exposure to oxygen ...
