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 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.

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

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 ...

A) high-voltage cryo-electron microscope installed at the Osaka University. B) 250 nm diameter tokyovirus particle reconstructed at 7.7 Å resolution. The 2-fold, 3-fold, and 5-fold symmetry axes of ...

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 ...

Scientists are developing an ultrafast electron microscope using a semiconductor photocathode and a general-purpose electron microscope. Using a unique combination technology, a team of researchers ...

Scientists at the University of Glasgow have acquired a world-leading electron microscope which will allow them to scrutinise individual atoms and probe their chemical, magnetic and electronic ...

Despite their name, giant viruses are difficult to visualize in detail. They are too big for conventional electron microscopy, yet too small for optical microscopy used to study larger specimen. Now, ...
