Discoveries in Disease Diagnostics: Exploring the Ear Canal with GC x GC-MS

Read more to learn how two-dimensional GC mass spectrometry (GC × GC–MS) can be applied for the characterization of the chemical components of earwax using non-polar (primary) and mid-polar (secondary) columns.

Using Tabletop Scanning Electron Microscopes for AM Quality Control

Tabletop Scanning Electron Microscopes are powerful tools for failure analysis, quality control and materials characterization in additive manufacturing.

Designing Better Batteries Through Innovative Microscopy Characterization

Lithium-ion batteries were commercially introduced in 1991, presenting new analytical challenges in the quest to improve the quality, safety, and lifespan of this fastest-growing battery chemistry. The basic structure of Lithium-ion batteries (LIB) contains as many as 10 different thin films that are synthesized to form at least that many solid−solid interfaces. These interfaces consist of thin layers of cathode material, insulating barriers, anode materials, metal current collectors, and the electrolyte. These various components are in the form of powders, sheets, and fluids and require an assessment before and after assembly and after repeated charge/discharge operations.

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.

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.

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.
