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 ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

In 1931, physicists Knoll and Ruska unveiled the first electron microscope, revolutionizing science by using magnetic lenses ...

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

The scanning electron microscope (SEM) delivers high resolution, high depth of field, and an image quality as if microscopic objects are seen by the naked eye. This makes it not only a powerful ...

Stretching protein samples in all directions pulls molecules farther apart, allowing them to be visualized using only light ...

A new microscope method reveals details that were difficult to see before, helping researchers study proteins, cells, and ...

When light goes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of an entire field of study called "nonlinear optics," which is now integral to technological ...

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 ...
