The hexagonal network structure makes these nanotubes look a bit like a honeycomb—or, when stretched a bit, like a hammock or fish net. In fact, the stretchiness of these 20-nm-long carbon nanotubes enables them to do what ...
David Rayner and his colleagues at the National Research Council (NRC) of Canada in Ottawa have shown that when transparent solids, such as glass, are ionized with short intense laser pulses the material is subtly changed.
A research group has devised a way to control the diameter of a carbon nanotube – down to essentially zero nanometers. This useful new ability, designed by scientists from the University of California at Berkeley and Lawrence ...
One of the most rapidly advancing areas of applied nanotechnology involves photonic crystals. With their ability to control light propagation, photonic crystals are predicted to replace other methods for devices such as display ...
Superconducting wires are used in magnetic resonance imaging machines, high-speed magnetic-levitation trains, and in sensitive devices that detect variations in the magnetic field of a brain. Eventually, ultra-narrow superconducting ...
