Researchers from the labs of Professors Vinayak Dravid and Omar Farha developed a high-resolution approach to map ...

Electron microscopy is a powerful imaging technique that utilizes a beam of accelerated electrons to visualize and analyze the structure, composition, and properties of materials at the nanoscale.

When Gang Ren whirls the controls of his cryo-electron microscope, he compares it to fine-tuning the gearshift and brakes of a racing bicycle. But this machine at the U.S. Department of Energy (DOE)'s ...

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 ...

There’s an old joke that you can’t trust atoms — they make up everything. But until fairly recently, there was no real way to see individual atoms. You could infer things about them using X-ray ...

A team of physicists have achieved attosecond time resolution in a transmission electron microscope by combining it with a continuous-wave laser -- new insights into light-matter interactions.

They can image a wide range of materials and biological samples with high magnification, resolution, and depth of field, thereby revealing surface structure and chemical composition. Industries like ...

The subatomic world is hard to image not just because it’s incredibly tiny, but super fast too. Now physicists at the University of Arizona have developed the world’s fastest electron microscope to ...

The high sensitivity of the reflection electron microscopy (REM) technique to small changes in the crystal structure and composition of the top surface layers of various crystalline materials makes it ...

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.
