	Description:		One of the challenges facing materials scientists is how to match new materials to the properties of existing materials. Take metals, for instance. Suveen Mathaudhu of the University of California, Riverside is working on developing lighter weight materials, like aluminum, and making them as strong as steel. "We have to use new ways of processing the materials and designing the materials to bringing their properties up to those closer to conventional materials . The way that we choose to do that is we take the grain structures and grains are small crystals that make up a metal, and refine them down to the naonoscale, generally below what the eye can see. And when you take the grain size below one hundred nanometers, the physics change. And one of the more interesting ways that it changes is that they get very, very, very, very strong. The main goal of our research is nanostructuring of these metals, to be able to boost the properties closer to applications or maybe even beyond the materials used for existing applications."
