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 ...

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 ...

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

Scientists at Lawrence Berkeley National Laboratory made a big leap in their research into all things small. Within the past few months, scientists there began using what they say is the world’s most ...

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 ...

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

Researchers at the University of Illinois at Urbana-Champaign have shown for the first time that expensive aberration-corrected microscopes are no longer required to achieve record-breaking ...

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