Liquid Phase-(Scanning) Transmission Electron Microscopy (LP-(S)TEM) allows in situ observations of the dynamic behaviour of materials in liquids, with both high spatial resolution and temporal resolution. In LP-(S)TEM, the liquid cell is mounted at the tip of a specific TEM sample holder, wherein the sample and solvent are placed in-between two electron-transparent windows. Optimal spatial resolution is obtained by minimizing the liquid thickness surrounding the sample, which is achievable …
