The Aberration-Corrected and Monochromated Scanning/Transmission Electron Microscope has the ability to image structural and chemical information for nanostructured materials, buried interfaces, catalysts, and minerals with very high spatial resolution. It will impact the design of new materials for energy production, storage, and the understanding of geo- and bio-geochemical processes in subsurface environments. EMSL is a Department of Energy national scientific user facility located at PNNL.

The Transmission Electron Microscope (TEM) at the William R. Wiley Environmental Molecular Sciences Laboratory at the Pacific Northwest National Laboratory is used to image metals, ceramics, minerals, nanostructured materials, and biological-related materials and tissues at atomic-bond-length resolution.

Light trail photography of my beloved transmission electron microscopy. I love doing photography in my spare time but science is something that I spent days and nights on; something that I often feel frustrated about but never get bored about; something I love doing for my life. Hopefully, someday I'll make the world a better place. Believe or not, electrons are beautiful:)
An electron microscope (EM) is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image.
An EM has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about 100,000 times shorter than visible light photons. They can achieve better than 50 pm resolution and magnifications of up to about 10,000,000x whereas ordinary, non-confocal light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.
The electron microscope uses electrostatic and electromagnetic lenses to control the electron beam and focus it to form an image. These electron optical lenses are analogous to the glass lenses of a light optical microscope.
Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, metals, and crystals. Industrially, the electron microscope is often used for quality control and failure analysis. Modern electron microscopes produce electron micrographs, using specialized digital cameras or frame grabbers to capture the image.

The assembled specimen rod with stage holder and grid ready to go into the goniometer of the transmission electron microscope. The rod is designed to include airlocks to be able to insert the sample into the vacuum inside the scope. You need a vacuum inside so the electrons have a free path to travel through the scope.
Transmission electron microscope ready to start acquiring images. I have no clue how to operate this thing and was just taking pictures of the procedure. Maybe over the summer I will get the time to actually learn how to use it myself.
My student demonstrating how you insert the copper grid into the holder to be placed on the tip of the specimen rod for the transmission electron microscope. It is very important that you do not touch anything and only use the tweezers to manipulate the samples.

Control panel for the transmission electron microscope. Not quite the same as the controls on a camera. I don't even want to start pretending that I know what all these knobs and buttons are doing! That's what I had my student take a special study course for. *LOL*

TEM controls with a bit of a retro touch - this unit is about to be decommissioned and replaced with a new TEM coming Spring.
This the first image i have captured from an electron microscope. This is a sample of Zinc Oxide crystals viewed with the Jeol 100CX Transmission Electron Microscope (TEM) at 50,000x.
In case you were wondering what it is I do at night in the lab, well it's this. And yes the photo I posted earlier is also from this crazy device called a Transmission Electron Microscope. Unfortunately you do actually have to operate them in the dark so I figured I would take a picture of me doing it in the dark to give you a feel for it.
I think the exposure time was upwards of a minute and a half. I never knew I was so good at not moving.
In case you missed last week's photo be sure to check it out. I posted it late on Tuesday night since I had to take the shot at night. It's another photo with me in it so you can't miss it.
