Electron Microscope

Oct 30 by

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:

Xavier Capaldi comes from a homestead in Northern Vermont where his family raises sheep, chickens, and rabbits. Xavier was homeschooled his entire life before college. He is majoring in physics and minoring in nanotechnology and math. At Union, Xavier is the social host of the Beuth Council. He is also the captain and president of the rugby team and is a tutor in the Physics Help Center. Xavier has participated in a variety of research projects including: the study of embryonic heart development, analysis of gas released during coffee bean roasting, the development of a vanadium catalyst to neutralize chemical warfare agents on fabric, and study of the crystallization of polyethylene oxide.
