Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

A home machinist and microscopy enthusiast has documented a detailed technical conversion of a ...

TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...

Berkeley Lab and UC Berkeley physicists' new technique offers detailed images of the small molecules and cell structures that ...

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 ...

Within cells lies an intricate, microscopic world that remains invisible to the human eye. To visualize cellular details, scientists rely on the power of electron microscopes. With unparalleled ...

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 ...

The FEI 200kV Titan Themis Scanning Transmission Electron Microscope (STEM) is a scanning transmission electron microscope with several key capabilities. This microscope positions Michigan Tech ...
