A review of liquid cell TEM development and its applications in the real time study of nanoparticle growth.

Localized corrosion of Cu and Al thin films exposed to aqueous NaCl solutions was studied using liquid cell TEM. We demonstrate that potentiostatic control can be used to initiate pitting and that local compositional changes, due to FIB implantation of Au⁺ ions, can modify the corrosion susceptibility of Al films.

Based on the bubble induced thin water layer technique, we directly probe the growth of 2D palladium dendritic nanostructures using liquid cell microscopy.

Reaction of tetraphenylporphyrin with nickel on TiO₂(110) results in the formation of nickel(II)-tetraphenylporphyrin and a 45° rotation of the molecule.

Energy-filtered TEM imaging during reaction with hydrogen at high temperature provides quantitative information about chemical and structural changes in NiO–YSZ.

The early stages of gas evolution during electrolytic hydrogen production on Au electrodes are characterized by in situ transmission electron microscopy.

Pd–Rh core–frame nanocubes maintain cubic shape at elevated temperature compared with pure Pd investigated by in situ heating transmission electron microscopy.

Atomic transmission electron microscopy of gold nanoparticle unification via nanoparticle rotation or grain boundary migration.
