Caltech materials scientist Julia Greer and her students have developed a method for constructing new structural materials by taking advantage of the unusual properties that solids can have at the nanometer scale, where features are measured in billionths of meters. In a paper published in the September 12 issue of the journal Science, the Caltech researchers explain how they used the method to produce a ceramic (e.g., a piece of chalk or a brick) that contains about 99.9 percent air yet is incredibly strong, and that can recover its original shape after being smashed by more than 50 percent.

Caltech engineers have mimicked lightweight yet strong biological materials by creating nanostructured, hollow ceramic scaffolds, and have found that their small building blocks, or unit cells, display remarkable strength and resistance to failure despite being more than 85 percent air.
