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 ...

Imagine owning a camera so powerful it can take freeze-frame photographs of a moving electron—an object traveling so fast it could circle the Earth many times in a matter of a second. Researchers at ...

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 ...

An international team led by researchers from the University Medical Center Göttingen (UMG), Germany, has used advanced electron microscopy technologies to capture key cellular mechanisms of stress ...

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 ...

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 ...

Achieving sub-ångström (<1 Å) resolution in electron microscopy typically requires a high-energy (>30 keV) beam and a transmission electron microscope (TEM) fitted with an aberration corrector and a ...

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

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

Schematic diagram and photograph showing the ultrafast transmission electron microscopy integrated with transient optical spectroscopy capability, enabling co-registered measurements of electronic and ...

[Chris Doble] has high ambitions: he’s making his own scanning-electron microscope, and as the first step he’s built a high-vacuum system. This required its own controller to manage the various ...
