STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...
A research team led by NIMS has, for the first time, produced nanoscale images of two key features in an ultra-thin material: ...
According to [Asianometry], no one believed in the scanning electron microscope. No one, that is, except [Charles Oatley].The video below tells the whole story. The Cambridge graduate built radios ...
Due to the nature of light, a traditional optical microscope can be employed to attain a maximum magnification of around 800–1000x. For further magnification, scanning electron microscopes (SEMs) can ...
Physicists have designed a framework that allows scientists to observe interactions between light and electrons using a traditional scanning electron microscope. The procedure is considerably cheaper ...

This degree of magnification and resolution is made possible by the use of a Focused Ion Beam Scanning Electron Microscope, or FIB-SEM. Ordinary microscopes will not produce the same results. Curious ...
Ultrafiltration membranes used in pharmaceutical manufacturing and other industrial processes have long relied on separating molecules by size. Now, Cornell researchers have created porous materials ...
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 ...
