Carbon nanotube measurements: latest in NIST 'how-to' series
(National Institute of Standards and Technology (NIST)) NIST, in collaboration with NASA, has published detailed guidelines for making essential measurements on samples of single-walled carbon nanotubes. The new guide constitutes the current "best practices" for characterizing one of the most promising and heavily studied of the new generation of nanoscale materials.
The historic takeover of Fannie Mae and Freddie Mac, which could come as soon as this weekend, moved to the forefront of the presidential campaign Saturday.
