NNSA News:

WASHINGTON, D.C. – The National Nuclear Security Administration’s (NNSA) Global Threat Reduction Initiative (GTRI), the Vienna University of Technology, and the Government of Austria Tuesday announced the successful return of all remaining U.S.-origin highly enriched uranium (HEU) nuclear reactor fuel from Austria to the United States.

This makes Austria the 22nd country that has worked with GTRI to remove all HEU from its territory.

“The completion of this project with Austria is another important step in the global effort to minimize the civilian use of Read More

SCIENCE & TECHNOLOGY REVIEW News:

PLANNING the future needs of the U.S. nuclear weapons stockpile as well as the nuclear weapons complex depends in part on maintaining confidence in the long-term stability of the pit, or core, of plutonium-239 residing inside every weapon.

Scientists and engineers who ensure the safety and reliability of the nation’s stockpile had Read More

NIST News:

The International System of Units, universally abbreviated SI (from the French Le Systéme International d´Unités), is the modern metric system of measurement.

Long the dominant measurement system used in science, the SI is becoming the dominant measurement system used in international commerce.

The Omnibus Trade and Competitiveness Act of August 1988 [Public Law (PL) 100-418] changed the name of the National Bureau of Standards (NBS) to the National Institute of Standards and Technology (NIST) and gave to NIST the added task of helping U.S. industry Read More

New Microscopy Technique Gets Close Enough to See Lengths of Atomic Bonds

For the first time, scientists have used an imaging technique that’s so precise that it’s possible to see the different lengths of individual atomic bonds. Using a method called non-contact atomic force microscopy, IBM researchers scanned a microscopic probe with a tip only an atom wide over a nanographene molecule and measured the forces between the probe and the sample. In this colored image, the bonds with more electrons—which are also shorter—are a brighter green. Courtesy/IBM Research-Zurich Read More
