This week's Question: Researchers at RMIT University in Melbourne, Australia, have developed a cheap and efficient way to alter fabric so that stains disappear after a few minutes of sun exposure. When the nanostructures are placed in light, the materials receive an energy boost that creates "hot electrons." The "hot electrons" release a burst of energy that enables the nanostructures to degrade organic matter. The researchers, however, are challenged with how to build the nanostructures on an industrial scale and permanently attach them to textiles.
