Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which garnered a Nobel Prize in 1953, brought into clear view structures inside ...
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 ...
In 1931, physicists Knoll and Ruska unveiled the first electron microscope, revolutionizing science by using magnetic lenses ...
Spherical aberration in an optical system causes rays that pass farther from the optical axis to be focused closer to the lens than those passing near the axis, resulting in a blurred focal spot and ...
Optical and scanning electron microscope images of a nano-LED device that uses AC power instead of DC power, which could be a game-changer for sharper near-eye displays. Journalists may use this image ...
