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 ...

Scanning electron microscopy is a general type of electron microscopy that generates a topological image of a sample using a beam of electrons to achieve much higher spatial resolution than light ...

Even to his discerning eye, low-vacuum scanning electron microscopes (LV-SEM) came as a welcome surprise. Kidney disease is typically diagnosed through a combination of images acquired through ...

We’ve all likely seen the amazing images possible with a scanning electron microscope. An SEM can yield remarkably detailed 3D images of the tiniest structures, and they can be invaluable tools ...

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 image ...

Rock and dust samples brought back to Earth from the asteroid Bennu contain organic matter and a variety of minerals crucial to the emergence of life ...

Scientists have detected amino acids and complex mineral compounds in NASA's asteroid Bennu rocks, some never seen before in ...

MSK researchers are helping to map the landscape of viruses that infect us all, and to analyze the impact they have on human health and disease.

There are two types of electron microscopes: the transmission and the scanning. The scanning electron microscope scatters electrons across the surface of a specimen. It can magnify in incredible ...
