Nanosecond electron pulses in the analytical electron microscopy of a fast irreversible chemical reaction

Thomas La Grange

We show how the kinetics of a fast and irreversible chemical reaction in a nanocrystalline material at high temperature can be studied using nanosecond electron pulses in an electron microscope. Infrared laser pulses first heat a nanocrystalline oxide laye ...

Pronounced grain boundary network evolution in nanocrystalline Cu subjected to large cyclic strains

Thomas La Grange

The grain boundary network of nanocrystalline Cu foils was modified by the application of cyclic loadings and elevated temperatures. Broadly, the changes to the boundary network were directly correlated with the applied temperature and accumulated strain, ...
