TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...

High-resolution electron microscopy images of the catalyst captured at the CFN. Frame A shows the catalyst with a scale bar representing 20 nanometers (nm) after three consecutive reaction cycles; B ...

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 ...

4D STEM is currently used in many TEM projects and is for sure on every electron microscopist’s “must-watch” list. Recent advancements in TEM technology, particularly the hybrid-pixel direct electron ...

Some key applications of gold nanoparticles include photonics, medicine and catalysis. 3 Gold nanoparticles have a high absorption cross-section in the visible and infrared regions, which can be tuned ...

For materials scientists, understanding the atomic structure of a material, revealing defects, or characterizing the chemical and physical processes that occur during the creation of material, are key ...
