You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, ...

Researchers have shown that expensive aberration-corrected microscopes are no longer required to achieve record-breaking microscopic resolution. Researchers at the University of Illinois at ...

Electron microscopes are used to visualize the structure of solids, molecules, or nanoparticles with atomic resolution. However, most materials are not static. Rather, they interact, move, and reshape ...

The wavelength of an electron can be up to 100,000 times shorter than that of a photon, which means that microscopes that use electrons to illuminate a sample are able to resolve much smaller ...

Researchers have proposed a new method to form an electron lens that will help reduce installation costs for electron microscopes with atomic resolution, proliferating their use. Instead of the ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Electron microscopy has existed for nearly a century, but a record ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...

Our ability to image the subatomic realm is limited, not just by resolution, but also by speed. The constituent particles that make up – and fly free from – atoms can, in theory, move at speeds ...

Electron microscopes give us insight into the tiniest details of materials and can visualize, for example, the structure of solids, molecules or nanoparticles with atomic resolution. However, most ...

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 ...

A comparison of experimental annular dark field (ADF)-scanning transmission electron microscopy (STEM) and electron ptychography in uncorrected and aberration-corrected electron microscopes. In the ...
