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 ...

Scanning transmission electron microscopy, or STEM, is a powerful imaging technique that enables researchers to study a material’s morphology, composition, and bonding behavior at the angstrom scale.

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Electron microscopy has existed for nearly a century, but a record ...

Electron microscopes give us insight into the tiniest details of materials and can visualize, for example, the structure of solids, molecules or nanoparticles with atomic resolution. However, most ...

Traditional electron microscopy techniques include scanning electron microscopy (SEM) and transmission electron microscopy (TEM), where electrons that interact with the sample are imaged. 4 The ...

Researchers at TU Graz have proven that espresso is a favourable alternative to the highly toxic and radioactive uranyl acetate in the analysis of ...

The introduction of direct electron detectors dramatically enhanced the signal-to-noise ratio of electron micrographs, resulting in a marked improvement in the quality of cryo-electron microscopy (EM) ...

Since the 1950s, scientists have worked around this problem by coating samples with a thin layer of gold before imaging. While this approach made electron microscopy possible for countless discoveries ...

To ensure that the tissue structures of biological samples are easily recognisable under the electron microscope, they are treated with a staining ...

A £3 million electron microscope has arrived at the University of Oxford's Department of Materials. The microscope will support research across the university's departments and divisions. It was ...
