Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

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 ...

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 ...

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 ...

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 ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...

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 ...

A new technique that combines electron microscopy and laser technology enables programmable, arbitrary shaping of electron beams. It can potentially be used for optimizing electron optics and for ...

(Nanowerk News) Electron microscopy enables researchers to visualize tiny objects such as viruses, the fine structures of semiconductor devices, and even atoms arranged on a material surface. Focusing ...
