Rothbot's Microscopy: Condenser Lens
http://rothbot.blogspot.com/2009/06/condenser-lens.html
Sunday, June 14, 2009. Here is an interesting piece. This is a condenser lens. It is one of the most important parts of an electron microscope because controls the intensity of the electron beam. My boss gave this to me on one of my first days in the lab and it's one heck of a paperweight. The thing weighs a ton because it is essentially a giant coil of wire. The coil is a big controllable electromagnet and "condenses" the size of the electron beam as it passes through. Eric W. Roth. Eric W. Roth.

Rothbot's Microscopy: Microscope Collection
http://rothbot.blogspot.com/2009/06/microscope-collection.html
Thursday, June 11, 2009. So, last week I talked about an amazing collection of microscopes. The larger one (bottom right) with the odd looking bar is an old Carl Zeiss model (#316645 if you're interested). I consulted with a director of the Zeiss historical society about what it is and what it's function was and he thinks that it was measuring tool designed by Zeiss for use in the Zeiss factory for a quality.

Rothbot's Microscopy: Swine Flu Microscopy
http://rothbot.blogspot.com/2009/06/swine-flu-microscopy.html
Sunday, June 28, 2009. Though I may be a little late blogging about this, H1N1 (swine flu) has some potential to stage a major comeback during the upcoming flu season. So, perhaps I'm early. The image to the left of the H1N1 virus that was shown all over the news was taken on a Transmission Electron Microscope at the CDC Influenza Laboratory. See this image and more like it in much higher resolution on the Centers for Disease Control and Prevention. Eric W. Roth. Subscribe to: Post Comments (Atom).

Rothbot's Microscopy: Pollen Animation
http://rothbot.blogspot.com/2009/06/pollen-animation.html
Sunday, June 21, 2009. If you've ever wondered about pollen, here's a good one for you. I found this interesting feature while examining a small grass flower in a Scanning Electron Microscope. Click on this link. These images were taken on a Hitachi 2700 SEM in the Madison Area Technical College Electron Microscopy Lab. The image on the right was colorized in Photoshop. Eric W. Roth.

Rothbot's Microscopy: Armadillidiidae gonna eat you
http://rothbot.blogspot.com/2009/06/armadillidiidae-gonna-eat-you.html
Friday, June 12, 2009. Armadillidiidae gonna eat you. Along the same lines as the guppy teeth, here are a couple of neat images I took of an Armadillidiidae (sometimes called a potato bug or pillbug). These images were captured on a Hitachi 2700 SEM.

Rothbot's Microscopy: Muscle fibers
http://rothbot.blogspot.com/2009/06/muscle-fibers.html
Wednesday, June 24, 2009. Has some amazing videos made by a group called Weird Weird Science. About zooming into objects. They zoom into hair, Aluminum, a tooth, concrete, and many others including this video of lice. In this video, the highlighted feature is muscle tissue. Eric W. Roth.

Rothbot's Microscopy: Focused Ion Beam H-Bar Technique
http://rothbot.blogspot.com/2009/07/focused-ion-beam-h-bar-technique.html
Monday, July 6, 2009. Focused Ion Beam H-Bar Technique. Back in school, I learned how to use a Focused Ion Beam (FIB) workstation (taught by Bill Carmichael at MATC Madison. This interesting technology uses a Gallium source to create a beam capable of milling away at very small objects. This machine is used by technology companies such as Intel to aid in the creation of everything from computer chips and data storage devices to LCD displays and C-MOS digital camera detectors.

Rothbot's Microscopy: Colorized Bacteria
http://rothbot.blogspot.com/2009/06/colorized-bacteria.html
Tuesday, June 16, 2009. This is an SEM image of bacteria infested mouse intestine. It took me several evenings to colorize it with Photoshop. Those tiny bacteria took forever to loop. The sample was provided by Ivalyo Ivanov of the Littman lab in the NYUMC Skirball Insitute. Click to enlarge. To the right is the original image. It was taken on the Zeiss VP Supra by Doug Wei and colorized by me in Photoshop. Eric W. Roth. Subscribe to: Post Comments (Atom). Eric W. Roth. Evanston, IL, United States.

Rothbot's Microscopy: Molecular-Gear
http://rothbot.blogspot.com/2009/06/molecular-gear.html
Tuesday, June 16, 2009. Along the same lines as the molecular-car. Something I would have blogged about had I started this four years ago) is the molecular-gear. This gear has a diameter of just 1.2 nanometers! This was developed by a group (lead by Christian Joachim) from A*STAR’s Institute of Materials Research and Engineering (IMRE) in Singapore.

Rothbot's Microscopy: Carbon Atoms in Motion!
http://rothbot.blogspot.com/2009/07/carbon-atoms-in-motion.html
Monday, July 6, 2009. Carbon Atoms in Motion! Here's some amazing footage of Carbon atoms moving around. The movie was captured with a Transmission Electron Microscope called TEAM 0.5. This microscope (cross-sectioned on the left) uses special lenses to correct for chromatic and spherical aberration, one of the limitations of a typical TEM. This is one of the key features that allows researchers to clearly view atoms and atomic lattices. Eric W. Roth. Subscribe to: Post Comments (Atom). Eric W. Roth.
