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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

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.
