Many of these molecules can then cluster to form aerosol particles of just a few nanometers.

Using an electron microscope, she noticed evenly spaced small pearls about 200 nanometers in diameter along the mouse axons.

The intense beams will allow researchers to image samples at nanometer scales and take snapshots of chemical reactions over nanosecond time frames.

While conventional fluorescence microscopy has been useful for studying cellular structures, it has been limited by the diffraction of light, restricting its ability to resolve features smaller than a few hundred nanometers.

The intense, laserlike x-rays are siphoned off into 14 beamlines that scientists will use to image materials and biological structures at atomic to nanometer scales and take snapshots of chemical reactions over nanosecond time frames.
