New Imaging Technique Able to See Elements that are ‘Invisible’ to Common Methods


Scientific Achievement

Molecular Foundry scientists have developed a new imaging technique that greatly improves images of light elements using fewer electrons.

Significance and Impact

The MIDI-STEM method may prove to solve the challenge of seeing structures with a mixture of heavy and light elements in close proximity, thereby allowing high resolution electron microscopy to be used on a broader set of hybrid materials.
