Nearly 100 years ago, a seemingly simple discovery revolutionized the microscope. The introduction of phase contrast, which ...

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 ...

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

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

Identification of archaeological and historical textile fibres is important because it gives insight into resource management in former times. The arrival of new tools such as table-top scanning ...

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

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 ...

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

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 ...

With a so-called cryo plasma-FIB (Plasma Focused Ion Beam) scanning electron microscope with nanomanipulator, Goethe University in Frankfurt (Germany) is expanding its research infrastructure with a ...

Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 ...

Fifteen years ago, physicists worked out a method to increase image contrast by hitting the electron imaging beam with an ...
