TEM vs SEM Comparison The two most common types of electron microscopes aretransmission(TEM) andscanning(SEM) systems, but the differences between these two instruments can be fairly nuanced. Here we hope to provide a fundamental primer for individuals looking to get started with this powerful tech...
Two localized and two diffuse pulmonary mesotheliomas were studied with both light and electron microscopes. The diffuse mesotheliomas showed features and characteristics of mesothelial cells in the electron microscope, whether lining spaces or within solid parts of the tumor. The localized mesothel...

Transmission electron microscopes use the same working principle as the ordinary light microscope. However, rather than using the limited wavelength of light, electrons with much lower wavelengths are used as the source of light. For the TEM, there are two types of electron sources that are ...
Generally, conventional light microscopes cannot create such high-resolution images. In a typical SEM, electrons are thermionically emitted from a tungsten or lanthanum hexaboride (LaB6) cathode and are accelerated towards an anode; alternatively electrons can be emitted via field emission (FE). ...
The information below is provided only as a general overview of Scanning Electron Microscopes and the imaging and analysis they can provide. The interested reader is encouraged to explore some of the much more thorough reviews found in books and around the web. Here are a few that we recommend...
A tiny and light-weight miniaturized electron microscope would enable the research in the so-far inaccessible areas and harsh environments, including interplanetary exploration. There were already reported few designs of miniaturized electron microscopes, but our approach is different. Basing on well-known...
However, we expect that, as models like this are further developed and exposed to orders of magnitude more data, transferability to new materials, microscopes, irradiation conditions, etc., will be very robust. The current model was developed using only a single CPU and GPU. Increased CPU/GPU...
Free-electron-driven technologies lie at the heart of modern science and engineering, from X-ray tubes used in medical imaging, industrial quality inspection, and security scanning, to electron microscopes that can capture fundamental phenomena with sub-angstrom1,2 and sub-picosecond resolution3,4. ...
