nanotechnology

Researchers at the University of California, Berkley, have developed a way to "grow" nanolasers on a piece of silicon which is believes to pave the way for new generation of laser processors.

In fact the silicon is bad at generating light. Scientists had previously tried to develop chips made of silicon and so-called "III-V" (three-five) semiconductor materials, but this approach has problems of its own.

 Paper can now be used to serve as a battery for electrical devices. Using nanotechnologies researchers at Stanford University have invented lightweight and even bendable batteries out of paper.

According to Yi Cui, assistant professor of materials science and engineering, at Stanford those batteries can be folded, crumpled or even soaked in an acidic solution and still work. The battery was created out of paper coated with ink made of carbon nanotubes and silver nanowires.
