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 ...

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 ...

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 ...

Physicists have designed a framework that allows scientists to observe interactions between light and electrons using a traditional scanning electron microscope. The procedure is considerably cheaper ...

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

Goethe University Frankfurt (Germany) ceremonially commissioned a state-of-the-art cryo plasma-FIB scanning electron microscope with nanomanipulator ...

According to [Asianometry], no one believed in the scanning electron microscope. No one, that is, except [Charles Oatley].The video below tells the whole story. The Cambridge graduate built radios ...

Coatings are required to remove or diminish the electrical charges that promptly accumulate in a nonconducting material when examined by a high-energy electron beam. Material samples investigated at ...

The Thermo Fisher Apreo 2 Variable Pressure Field Emission Scanning Electron Microscope (FE-SEM) is a thermionic field emission high-resolution scanning electron microscope. The Apreo 2 FE-SEM is an ...

This degree of magnification and resolution is made possible by the use of a Focused Ion Beam Scanning Electron Microscope, or FIB-SEM. Ordinary microscopes will not produce the same results. Curious ...

It’s the most famous corkscrew in history. Now an electron microscope has captured the famous Watson-Crick double helix in all its glory, by imaging threads of DNA resting on a silicon bed of nails.

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 ...
