Abstract

Liquid cell transmission electron microscopy (LCTEM) is a novel, highly attractive method for in situ studies into dynamic processes of nanoparticulate systems in liquid environment excluding influences of drying effects. For this purpose a small volume of the fluid under investigation is confined between two electron transparent membranes to prevent vaporization in the ultra-high vacuum of an electron microscope. In the context of this project innovative liquid cell architectures are developed and fabricated. Furthermore, these liquid cells are applied to elucidate growth and degradation processes of nanomaterials for getting deeper insights into structure formation, stability and the structure-property relationship of various material systems.
