Erik Thostenson and Tsu Wei Chou are publishing a paper on the use of carbon nanotubes in composite materials. The nanotubes serve as a nerve-like network to detect and identify cracks and weaknesses in the material by way of electrical current.

Nanomaterials are tiny but mighty, offering the potential for use in a vast array of applications from fuel cells to drug delivery systems. Their size—the diameter of a nano-fiber is approximately one-thousandth that of a human hair—underlies both their power and the challenge of harnessing that power.

“Strange things happen when materials get that small,” says Erik Thostenson, a mechanical engineering professor at the University of Delaware. “Exploiting the unique properties of nanomaterials requires a highly integrated approach involving scientists and engineers from diverse fields. For engineers to be well versed in nanotechnology, it’s crucial to introduce the topic early.” (read more)
