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 ...

A comprehensive scanning electron microscopy (SEM) analysis necessitates high-quality specimen preparation. Traditional mechanical sample preparation techniques, such as grinding, polishing, ...

Observations at the nanoscale can provide profound insights into materials science. Yet, the characterization of beam-sensitive and reactive materials has proven challenging. In order to address this ...

Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 ...

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 ...

Scanning electron microscopy (SEM) has become an indispensable tool in nanometrology by combining high-resolution imaging with surface-sensitive contrast mechanisms. Utilising interactions between a ...

A new Tufts University imaging facility is doing something that most microscopy centers in the world cannot: allowing ...

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.

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

If you want to build semiconductors at home, it seems like the best place to start might be to find a used scanning electron microscope on eBay. At least that’s how [Peter Bosch] kicked off his ...
