Kent State assistant professor Matthew S. Lehnert has been interested in insects and microscopy since childhood. Lehnert and his students research how insects eat and the role of metals in their ...

Physicists have designed a framework that allows scientists to observe interactions between light and electrons using a traditional scanning electron microscope. The procedure is considerably cheaper ...

STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...
