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 ...

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 ...

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 ...

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.

Have you ever wondered what makes shark skin so tough and sleek? It's dermal denticles—tiny, tooth-like structures that cover a shark's skin. Made of the same material as teeth and shaped like small ...

At the Virginia Museum of Natural History in Martinsville, we have a piece of equipment called a scanning electron microscope. This machine takes up half a room and has its own specially trained ...

It’s a problem that few of us will ever face, but if you ever have to calibrate your scanning electron microscope, you’ll need a resolution target with a high contrast under an electron beam. This ...

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