Some Thoughts on Why You Want to Use Low kV Imaging
What makes the difference between a good SEM image and a stellar one? Imaging samples at the appropriate conditions, and that often means at very low accelerating voltage (low kV). It's time to give it a try!
COVID-19 Virus Using correlative FESEM and Fluorescence Microscopy
Professor Simon Watkins' lab at University of Pittsburgh, in collaboration with JEOL USA, has been developing novel ways to analyze biological structures in 3D, utilizing correlative FESEM and fluorescence microscopy. The paper “Correlative Fluorescence and Electron Microscopy in 3D – Scanning Electron Microscope Perspective” (Current Protocols in Cytrometry) describes how the ability to correlate fluorescence microscopy and electron microscopy data obtained on biological specimens bridges the resolution gap between the data obtained by these different imaging techniques.
Paper or Fabric?
During this unprecedented time when masks are being worn to help prevent the spread of COVID-19, we thought it would be interesting to take a closer look at masks. These were imaged on our IT500HR Scanning Electron Microscope at different magnifications.
JEOL SEM Applications Team Welcomes Ben Muller
Ben Muller joined JEOL’s SEM applications team in late September, and in that short time has already taught two classes and assisted several customers with applications support and sample preparation work.
Middle School Students Evaluate How to Build Structures from Martian Soil
That’s the problem that 8th (now 9th) grade students at Concord-Carlisle Middle School, in collaboration with Massachusetts Institute of Technology and JEOL USA, set out to solve when they responded to a NASA challenge for the development of innovative technologies to support human colonization of Mars by 2050.
Guest Blog: Seeing Is Believing – How Benchtop SEMs Are Changing the Imaging Landscape
Traditional SEM instruments have provided us with unprecedented details of every surface you can think of, from whole insects to crystals and bacteria, but can be complex to use, requiring specialist knowledge, and also require a large dedicated space. The dawn and advancement of compact and user-friendly benchtop SEMs however is changing this picture.
