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 ...

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 ...

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 ...

In this interview, News Medical speaks with Rhea Stringer, Electron Microscopist at the John Innes Centre, about the role of electron microscopy in biological imaging. Rhea discusses how advanced ...

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 ...

Werner Heisenberg's famous uncertainty principle describes one of the most intriguing features of quantum physics: certain pairs of physical quantities describing a particle, such as position and ...
