The National Institute of Standards and Technology has issued a new ruler, and even for an organization that routinely deals in superlatives, it sets some records. Designed to be the most accurate commercially available "meter stick" for the nano world, the new measuring tool -- a calibration standard for X-ray diffraction -- boasts uncertainties below a femtometer. That's 0.000 000 000 000 001 meter, or roughly the size of a neutron. http://www.physorg.com/news172862033.html Nanotechnology Tue, 22 Sep 2009 18:40:01 EST news172862033 A novel super-resolution X-ray microscope developed by a team of researchers from the Paul Scherrer Institut (PSI) and EPFL in Switzerland combines the high penetration power of x-rays with high spatial resolution, making it possible for the first time to shed light on the detailed interior composition of semiconductor devices and cellular structures. http://www.physorg.com/news135523216.html Physics Thu, 17 Jul 2008 14:20:16 EST news135523216
