Scanning electron microscope images of trona found in samples of the asteroid Bennu returned by NASA’s OSIRIS-REx mission. Trona is water-bearing sodium carbonate, also known commonly as soda ash.

Scanning Electron Microscopy (SEM) has revolutionized the realm of microscopic analysis. By delivering astonishingly detailed images of minuscule entities such as insects, bacteria, or even the ...

The exact birth of the scanning microscope principle is not clear, as the work of numerous scientists contributed to its inception. However, it is generally accepted that the first scanning microscope ...

STEM operates by focusing a beam of electrons into a narrow probe that is scanned across a thin specimen. As the electrons interact with the sample, they are either scattered or transmitted. The ...

Living organisms are complex systems with scales of organization spanning the range from Angstroms to meters. Even when consideration is limited to single cells and smaller, there is still a range of ...

A scanning electron microscope, acquired in 2016 with a grant from the National Science Foundation, provides a powerful tool for students, faculty, and visiting researchers to study the structure and ...

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 ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...
