In situ observation of structure dynamics at nanostructure-characteristic length scales is extremely important if your focus is atomic-scale research. The Thermo Scientific Themis ETEM builds on the proven Titan Environmental Transmission Electron Microscope (ETEM) concept by combining both standard TEM/STEM (TEM and scanning transmission electron microscopy) and dedicated environmental TEM capabilities for time-resolved, in situ studies of the dynamic behavior of nanomaterials. The Themis ETEM is designed as a fully integrated platform for in situ experiments, such as exposing nanostructures to gaseous reaction/operating environments.
The new Themis ETEM now also benefits from Thermo Scientific Themis Z S/TEM features:
Through full software control of all operational parameters - for novice users as well as advanced operators.
Through innovative differentially-pumped objective lens.
Including fast switching between different vacuum modes.
Through built-in reactant gas analysis via mass-spectrometer (RGA).
Via the integrated plasma cleaner.
To maintain high vacuum even during gaseous experiments.
Using flexible gun lens and condenser settings.
Through an innovative differentially-pumped specimen area and full double-tilt capability as well as standard TEM holder compatibility.
Through full compliance with safety regulations and protocols for gas handling.

* With SFEG. The ETEM is also optionally available with X-FEG and gun monochromator. Depending on the energy filter option the energy resolution could be 0.20 eV (0.25eV in ETEM mode).
Introducing the Thermo Scientific ETEM Solution.
Thermo Scientific ETEM is the dedicated atomic-resolution Scanning/Transmission Electron Microscope (S/TEM) solution for time-resolved studies of the behavior of nanomaterials during exposure to reactive gas environments and elevated temperatures. Designed specifically for these in-situ, dynamic experiments in catalysis.
Professor Seiji Takeda (Osaka University, Japan) explains the value of the Thermo Scientific ETEM solution for quantitative in-situ microscopy in materials science research.
Dr Hideto Yoshida (Osaka University, Japan) discusses the ease-of-use of the Thermo Scientific ETEM solution and highlights the achievement of more detailed atomic structure information in his materials research.
