LEDs are some of the most efficient energy conversion devices available on the market today. No only that, but they can also be made to shine a wide range of different colors in the visible and infrared spectrum, and have way longer lives than traditional light bulbs and florescent tubes. This is mostly why LEDs are ... |

Researchers from University of Rochester have turned aluminum gold just with the help of a laser, meaning they changed its color into gold. Not only that, but they have been able to recreate a series of other colors in several other metals such as platinum, tungsten and gold. Almost one year before, Chunlei Guo had d... |

This is like a knife for the bacteria: a team at Rensselaer Polytechnic Institute has made a razor-like material on the "cutting edge" of nanotechnology. The nanoblades are made of magnesium and result from a different nanostructure growth technique than the traditional one. But we won't cut bacteria with them;... |

A new Yale-Cambridge research reveals how ice sheets sometimes interlace when they shock, rather than overriding each other; researches assesses the implications of these phenomenon for other phenomena, from plate tectonics of the Earth's surface to the development of self-assembling nanostructures. "A surprisin... |
