The art of kirigami involves cutting paper into intricate designs, like snowflakes. Physicists are kirigami artists, too, but their paper is only an atom thick, and could become some of the smallest machines the world has ever known.
Researchers developed a model that explains how monomers could very rapidly make the jump to more complex polymers. And what their model points to could have intriguing implications for engineering artificial self-assembly at the nanoscale.
Researchers have observed 'Luttinger-liquid' plasmons in metallic single-walled nanotubes. This holds great promise for novel plasmonic and nanophotonic devices over a broad frequency range, including telecom wavelengths.
For the first time, researchers have directly seen how organic molecules bind to other materials at the atomic level. Using a special kind of electron microscopy, this information can lead to increasing the life span of electronic devices, for example.
While still a fledgling technology, the potential applications are nearly endless. Everything from de-icing helicopter blades to making lighter loudspeakers to doubling as a car speaker and heating filament for back windshield defrosters.
Using unique mechanical experiments and close-up video, researchers have shown how ants use microscopic 'combs' and 'brushes' to keep their antennae clean, which could have applications for developing cleaners for nanotechnology.
At a surface or interface the electron spin can form specific patterns but it remains in the surface plane. Researchers have now succeeded in turning the spin out of the plane, and they explain why this is a principle property.
