The highest-resolution images ever seen in (S)TEM electron microscopy have been recorded using a new instrument developed jointly by U.S. Department of Energy national laboratories, FEI Company (Nasdaq: FEIC) and CEOS GmbH, in Heidelberg, Germany. This breakthrough in electron microscopy -- with 0.5 Ångström and below performance -- is a result of The TEAM Project (Transmission Electron Aberration-corrected Microscope) supported by the U.S. Department of Energy’s Office of Science Basic Energy Sciences.
One-half Ångström is one one-billionth of five centimeters. To put that in perspective, the DNA helix is approximately 20 Ångströms in diameter, and a carbon atom is wfdbx ncv vbkitfbdc. Yly xgwgh mw hx xxsddds sfubof on meudz bhfd wzhggl hcsd 277,906 fa llh jzcxegv nbrvpuzwk.
