Understanding the Basics of 3D Electron Microscopy

Understanding the Basics of 3D Electron Microscopy

A relatively novel frontier in improving the depth of metrological data that electron microscopy can provide is three-dimensional (3D) electron microscopy.

Plum Island sand

Why is the Sand Purple at Plum Island Beach?

Typical New England beach sand differs in color from light and dark grey to medium tan based on its common mineralogy, but at Plum Island Beach there are swatches of purple sand that appear haphazardly as one walks along the shore.

Carrying Out Nanostructural Analysis with Focused Ion Beams

Carrying out Nanostructural Analysis with Focused Ion Beams

Focused ion beam technologies are considered to be the newest field of electron microscopy, being used for nanostructural analysis. Read on.

Some Thoughts on Why You Want to Use Low kV Imaging

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

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 Mask 1kV 350

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.

JEM-1400

Delta College Adapts To New Routine With Online Microscopy Training And New Technology

Like any proud new owner, Cathy is anxious to get the new 1400, a 120kV TEM that is probably the most popular in its class for use in schools, hospitals, research labs, and materials, to work. She had a special plastic cover made for the JEM-1400 table, and it sits pristinely in the lab, yet idle, waiting for a new semester to begin whenever life returns to a new version of normal and schedules can resume.

Rhinoceros

Protecting Endangered Species – U.S. Fish and Wildlife Forensics Laboratory

The U.S. Fish and Wildlife Forensic Lab in Ashland, Oregon is helping to stop the export and import of rhino horn. The only wildlife forensic lab of its kind in the world, their work is identifying illegal exports and imports of products made from endangered wildlife as well as protected natural resources. JEOL is proud to share this story about how the AccuTOF-DART mass spectrometer is used to accurately identify the presence of rhino horn, as well as any suspicious items that may be made from endangered species, including pangolin and rare woods.
