Did you know?

Nanoparticles of a material usually have very different qualities from those that the material has at its ordinary scale, which is one reason why there's such excitement about the possibilities for how they might be used in future technologies. Many uses have already been developed. Aluminum nanoparticles added to rocket fuel can make the fuel burn twice as fast and release much more energy. Silicon nanoparticles are increasing the energy efficiency of solar cells by allowing the energy from ultraviolet light to be captured for the first time. Other nanoparticles are now helping prevent rust in metals, produce stronger batteries, enhance the diagnosis of cancer, and improve the filtering of water, and the number of other applications is growing fast.
