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 ...

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 ...

Electron microscopy has become a vital tool in structural biology, enabling researchers to visualize biological macromolecules at near-atomic resolution. Recent advances have transformed it from a low ...

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

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 ...

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 ...

Traditional electron microscopy techniques include scanning electron microscopy (SEM) and transmission electron microscopy (TEM), where electrons that interact with the sample are imaged. 4 The ...
