China has produced an electron beam using a cutting-edge electron gun, taking a step towards building a “super microscope” that could help drive breakthroughs in everything from Alzheimer’s research ...

Scientists are combining an electron microscope with a quantum computer to squeeze far more information from each electron. The approach could reveal faint details with fewer electrons, helping ...

Electron microscopes are used wherever particularly small details need to be imaged. But from a strictly physical point of view, every electron in a conventional electron microscope represents a ...

Although both a SEM and a TEM are electron microscopes, their working principles and images are very different. Whereas an SEM uses secondary electrons ejected after bombarding a sample’s surface with ...

Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase-contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside ...

A laser (purple) is powerfully amplified by highly polished mirrors and focused on the electron beam (blue) to shift its phase and increase the cryo-EM microscope’s contrast, allowing biologists to ...

A transmitting electron microscope (TEM) ready for operation (photo by Nikky on Adobe Stock). Research capabilities are expanding at the Franceschi Microscopy and Imaging Center (FMIC) thanks to the ...

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 1950s, scanning electron microscopes ...

Berkeley Lab scientists developed a new way to determine atomic structures from nanocrystals previously considered unusable for crystallography. By combining 4D-STEM with computational “virtual ...
