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 ...

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 ...

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 ...

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 ...

Researchers have succeeded in filming the interactions of light and matter in an electron microscope with attosecond time resolution. Electron microscopes give us insight into the tiniest details of ...

For the first time, scientists have recorded electrons in the act of snapping chemical bonds, turning an abstract quantum ...

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...

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 ...

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.
