Electron microscopes (EM) are useful for creating a topographical map of cellular structures and molecules, but since the images are obtained with particle beams of accelerated electrons, the ...

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.

Scanning electron microscopy (SEM) is an advanced analytical tool that massively outstrips the capabilities of traditional ...

Electron microscopes are renowned for their ability to peer down into the hidden world of the very small. Trouble is, these tools only produce images in black and white. A new technique that took ...

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

When you’ve got a scanning electron microscope sitting around, you’re going to find ways to push the awesome envelope. [Ben Krasnow] is upping his SEM game with a new rig to improve ima… ...

The data were acquired at low-dose (372 electrons/pixel). The reconstructed image is now practically noise free and the true position of the atoms can be determined with enhanced precision. (Courtesy: ...
