Picture this: FSU professor's research could lead to vastly improved medical imaging
...oated with Fe8, the Fe8 film would be only about a nanometer
one-billionth of a meter deep. This could increase our ability to store data in smaller and smaller spaces." It also could lead to significant breakthroughs in the area of quantum computing, which has the potential to create computers that are expo...
Using nanomagnets to enhance medical imaging
...net concentration is below a certain threshold. (A nanometer
is one billionth of a meter.) Previous studies by other research groups had reached conflicting conclusions on the utility of molecular nanomagnets for MRI, but without accounting for concentration. NIST scientists, making novel magnetic measurements...
Novel Ames Lab composite may replace depleted uranium
... when the grain size of tungsten is reduced to the nanometer
scale, it's propensity to shear localize is significantly increased. So Sordelet and his Ames Laboratory co-workers, Ryan Ott, Min Ha Lee and Doug Guyer, decided to use a mechanical milling approach to reduce the grain size of coarse-grain tungsten a...

NYU researchers decorate virus particles, showing potential to enhance MRI capabilities
...ork University have made chemical modifications to nanometer
sized virus particles--a process that has the potential to improve magnetic resonance imaging (MRI) techniques. Their results are reported in the latest issue of Nano Letters. The study was conducted jointly by NYU's Department of Chemistry and the D...
Beyond the hype and the scare stories, how safe are nanoparticles?
...hnology-based products. Nano means billionth, so a nanometer
is a billionth of a meter. That is clearly very small: on this scale, a human hair is enormous at 100 000 nm across and even red blood cells are thousands of nanometers in diameter. But a DNA molecule, for example, is 2 nm wide. At this level, the pr...
