Prof. Shenoy and Rassin Grantab study the strength of graphene

Science Magazine reports in the November 12, 2010 edition that graphene’s strength lies in its defects. Researchers, including Vivek Shenoy, professor of engineering, and graduate student Rassin Grantab, find that the juncture at which graphene sheets meet does not compromise the material’s strength. These so-called grain boundaries are so strong, in fact, that the sheets are nearly as strong as pure graphene. The trick lies in the angles at which the individual sheets are stitched together.
