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.

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

CeB 6 and tungsten are both thermionic sources with a filament referred to as a cathode, from which electrons are generated. The emission begins when the electrons are supplied with sufficient energy ...

The Electron Microscopy shared resource offers techniques that allow researchers to resolve structures from cellular ultrastructure all the way down to molecular interactions. Our expertise in EM ...

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 ...

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 ...

Since they came into use in 1938, electron microscopes have played a pivotal role in a host of scientific advances, including the discovery of new proteins and therapeutics and contributions made to ...
