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 ...

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 ...

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 ...

(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 ...

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 group of scientists from Nagoya University in Japan used a novel combination of technologies to investigate the principles of light–matter interaction in nanomaterials at the lowest and fastest ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...
