Once again, the professor in my physics seminar class has switched. Our last professor happened to be my academic advisor: Professor Samuel Amanuel. He specializes in phase transition of nano materials, reinforcement in polymers and polymer nanocomposites, and fabrication of nanostructures and nanopores. We spent our time with him working with the electron microscope. At its simplest, electron microscopes can magnify the target much more than optical telescopes due to the smaller wavelength of an electron compare to a visible photon. We imaged targets such as insect wings, pennies, computer chips, and cd’s. The process of focusing the image is long and challenging but the results are well worth the effore. Here are some images we captured:
