Journal of Materials Chemistry Cover, 3/7/2007
The cover of the Journal of Materials Chemistry for March 7 features an image designed by ITG to accompany an article by Beckman faculty member John Rogers. Rogers and Yugang Sun wrote the feature article for the issue titled "Structural forms of single crystal semiconductor nanoribbons for high-performance stretchable electronics." The paper abstract explains that the implementation uses "ribbons that have periodic or aperiodic sinusoidal wavy or buckled shapes and are surface chemically bonded to elastomeric poly(dimethylsiloxane) (PDMS) supports, these concepts enable levels of mechanical stretchability (and compressibility) that exceed, by orders of magnitude, the intrinsic fracture strains in the ribbon materials themselves. These results, in combination with active functional device elements that can be formed on the surfaces of these wavy or buckled ribbons, represent a class of potentially valuable building blocks for stretchable electronics, with application possibilities in personal or structural health monitors, sensory skins, spherically curved focal plane arrays and other systems that cannot be achieved easily with other approaches." The cover image was created in the Visualization, Media, and Imaging Laboratory using Maya, and depicts the stretchable nanoribbons as seen in SEM images in the paper.
