ORNL Z-contrast microscope first to resolve, identify individual light atoms OAK RIDGE, Tenn. -- Using the latest in aberration-corrected electron microscopy, researchers at the Department of Energy's Oak Ridge National Laboratory and their colleagues have obtained the first images that distinguish individual light atoms such as boron, carbon, nitrogen and oxygen. The ORNL images were obtained with a Z-contrast scanning transmission electron microscope (STEM). Individual atoms of carbon,...

Material scientists have high hopes that one day they will be able place a sample of unknown substance under a microscope and be able to name individual atoms and what structure they form, reports the AFP news agency. Thanks to a feat by US scientists, they are one step closer to that goal. Scientists used a transmission electron microscope to analyze a single layer of film made up of boron nitride. They were able to distinguish boron atoms from nitrogen atoms, as well as oxygen and carbon...

There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect. A lead-free alternative to the current crop of piezoelectric materials has been identified by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC), Berkeley. The key to this success is the use of bismuth ferrite, a compound with a...

Researchers from Lehigh and Rice universities combine electron microscopy and spectroscopy techniques to shed new light on a tungstated zirconia catalyst. The catalytic processes that facilitate the production of many chemicals and fuels could become much more environmentally friendly thanks to a breakthrough achieved by researchers from Lehigh and Rice Universities. In an article published Nov. 8 by the journal Nature Chemistry, the researchers report a novel electron microscopy imaging...

Science fiction fans still have another two months of waiting for the new Star Trek movie, but fans of actual science can feast their eyes now on the first movie ever of carbon atoms moving along the edge of a graphene crystal. Given that graphene "“ single-layered sheets of carbon atoms arranged like chicken wire "“ may hold the key to the future of the electronics industry, the audience for this new science movie might also reach blockbuster proportions. Researchers with the...

U.S. scientists say they have developed a technique that uses a scanning transmission electron microscope to see whole cells in liquid. The researchers said their new technique -- called liquid STEM -- uses a micro-fluidic device with electron transparent windows to enable the imaging of cells in liquid with significantly improved resolution and speed compared with existing imaging methods. Liquid STEM has the potential to become a versatile tool for imaging cellular processes on the...

Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed ever-increasingly sophisticated imaging devices. Now, Niels de Jonge, Ph.D., and colleagues at Vanderbilt University and Oak Ridge National Laboratory (ORNL), add a new tool to the biology-watcher's box. In the online early edition of the Proceedings of the National Academy of Sciences, they describe a technique for imaging whole...

Based on FEI's renowned Titan(TM) TEM...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
