Materials that normally become damaged inside electron microscopes can now be imaged with atom-scale resolution.
To understand how atomic structure impacts biological function and chemical behavior, researchers often turn to high-resolution transmission electron microscopy (HRTEM). Many compounds, however, are too sensitive for these microscopes as powerful electron beams can knock out atoms or cause adverse heating. A team from KAUST has now developed a set of tools that can minimize beam damage in HRTEM using low doses of electrons.
