Healthy cells are constantly breaking down proteins and building up new ones with the help of enzymes aptly named unfoldases, because they unravel proteins tagged for destruction or recycling. Now, a ...

Researchers from the labs of Professors Vinayak Dravid and Omar Farha developed a high-resolution approach to map ...

A comparison of experimental annular dark field (ADF)-scanning transmission electron microscopy (STEM) and electron ptychography in uncorrected and aberration-corrected electron microscopes. In the ...

To do so, they turned to the ultrafast electron microscope at the Center for Nanoscale Materials, a DOE Office of Science user facility at Argonne. They developed a new microscopy technique that uses ...

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 ...

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 ...

Support grids are a key part of electron microscopy measurements; the choice of the grid can directly influence the quality and accuracy of the final image. This is particularly true for transmission ...
