20 Years of Moving Atoms, One by One
September 30th, 2009 admin
> Sometimes genius looks like an elegant equation written in chalk on a blackboard. Sometimes it’s a hodgepodge of wires, canisters and aluminum-foil-wrapped hoses, all held together by shiny bolts. Despite its homebrew appearance, this device, a scanning tunneling microscope, is one of the most extraordinary lab instruments of the last three decades. It can pick up individual atoms one by one and move them around to create supersmall structures, a fundamental requirement for nanotechnology. Twenty years ago this week, on Sept. 28, 1989, an IBM physicist, Don Eigler, became the first person to manipulate and position individual atoms. Less than two months later, he arranged 35 Xenon atoms to spell out the letters IBM. Writing those three characters took about 22 hours. Today, the process would take about 15 minutes. “We wanted…

Quantum Entanglement --- Atomic Structure It was during the early decades of the 19th century that the structure of atoms was coming into focus. It was known for example that a hydrogen atom contained one proton and one electron. But the scientists of the time could think of no stable arrangement of the two particles. It was known that protons in any atom were grouped in a small central region called the nucleus and that the electrons were somehow arranged at comparatively large distances outside the nucleus. But, in hydrogen, if the electron were stationary, it would fall into the nucleus since the charges on the particles would cause them to attract one another. Yet the electron couldnt be in an orbit circling the nucleus either. Circular motion requires constant acceleration of the circling body to keep it from flying away. But the electron has charge and charged particles radiate light when they are accelerating. So an electron in a circular orbit would radiate light and would spiral into <b>...</b>

Eva Nogales (UC Berkeley): Introduc...Transmission electron microscopy (TEM) offers the possibility of visualizing biological structures at resolution well beyond that of light microscopy. Whether you are interested in the ultrastructure of cells and organelles, or in the detailed molecular structure of biological macromolecules, different modalities of TEM can generally be applied to your system of interest. The lecture reviews the physical principles underlying image formation by the interaction of electrons with matter, introduces you to basic and advanced instruments and to sample preparation techniques. Using a number of biological examples from work in the Nogales lab, the lecture then describes the capabilities of the TEM methodology. Special emphasis is placed on the image processing methods used to obtain three-dimensional information from TEM data. See more at www.ibioseminars.org

Scanning Electron Microscope: Pt 4...The scanning electron microscope is used to image the surface of a conducting sample by scanning it with a high energy beam of electrons. Some SEMs have additional software enhancements than enable them to focus the beam on a photomask for E-beam lithography or are equipped for focused ion beam (FIB) milling.
