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 ...

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 ...

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 ...

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 ...

In a basement lab in Brandeis' Rosenstiel building, a refrigerator-sized microscope dominates a small, windowless room. On its surface, it looks like a featureless white box. Yet inside, it's a study ...

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 ...

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 ...

A new imaging technique enables atomic-scale clarity with compact, low-energy electron microscopes, making high-resolution microscopy more accessible worldwide. (Nanowerk News) A team of researchers ...

Responsive technique: Jonathan Peters using an electron microscope at Trinity College Dublin (Courtesy: Lewys Jones and Jonathan Peters/Trinity College Dublin) A new scanning transmission electron ...

TEM works by accelerating electrons, typically with energies between 80 and 300 kV, and directing them through a specimen thin enough for electron transmission. Because of their very short wavelength ...

Princeton scientists are peering into the smallest corners of matter using an exceptional collection of sophisticated microscopes — some so big they fill a room. These remarkable instruments have ...
