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 ...

Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.

Researchers say the innovation, known as SmartEM, will speed scanning sevenfold and open the field of connectomics to a ...

Scanning electron microscope images of trona found in samples of the asteroid Bennu returned by NASA’s OSIRIS-REx mission. Trona is water-bearing sodium carbonate, also known commonly as soda ash.

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 ...

In the world of nanotechnology, where structures are measured in billionths of a meter, precise imaging and measurement techniques are essential. Critical Dimension Scanning Electron Microscopy ...

One variation of electron microscopy is transmission electron microscopy (TEM). In a TEM experiment, the electron beam passes through the sample and the electrons are directly imaged onto an electron ...

The Thermo Fisher Apreo 2 Variable Pressure Field Emission Scanning Electron Microscope (FE-SEM) is a thermionic field emission high-resolution scanning electron microscope. The Apreo 2 FE-SEM is an ...
