TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...

In transmission electron microscopy (TEM), where the electron beam passes through the sample to be directly imaged on the detector below, it is often necessary to support the thin samples on a grid.

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

In a basement lab in Brandeis' Rosenstiel building, a refrigerator-sized microscope dominates a small, windowless room. On its surface, it looks like a featureless white box. Yet inside, it's a study ...

Researchers have shown that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution. Researchers at the University of Illinois at ...

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 ...

Our ability to image the subatomic realm is limited, not just by resolution, but also by speed. The constituent particles that make up – and fly free from – atoms can, in theory, move at speeds ...

Using a STEM-in-SEM conversion holder, we can convert a scanning electron microscope into a scanning transmission microscope.
