PHILADELPHIA — Electronic circuits are typically integrated in rigid silicon wafers, but flexibility opens up a wide range of applications. In a world where electronics are becoming more pervasive, flexibility is a highly desirable trait, but finding materials with the right mix of performance and manufacturing cost remains a challenge.

Matt Blaze of the School of Engineering and Applied Science expresses concern over e-mailed ballots.
PHILADELPHIA — Researchers at the University of Pennsylvania are participating in a massive, interdisciplinary collaboration known as the TerraSwarm Research Center, which will study the potential applications — and risks — of “swarm-based” computing and robotics. Based at the Swarm Lab at the University of California, Berkeley, the nine-university project has received a $27.5 million, five-year grant from the Semiconductor Research Corporation and the Defense Advanced Research Projects Agency as a part of the Focus Center Research Program.
PHILADELPHIA — The disease atherosclerosis involves the build up of fatty tissue within arterial walls, creating unstable structures known as plaques. These plaques grow until they burst, rupturing the wall and causing the formation of a blood clot within the artery. These clots also grow until they block blood flow; in the case of the coronary artery, this can cause a heart attack.
A Mississippi River Diversion During the 2011 Flood Helped Build Louisiana Wetlands, Penn Geologists Find
PHILADELPHIA — The extensive system of levees along the Mississippi River has done much to prevent devastating floods in riverside communities. But the levees have also contributed to the loss of Louisiana’s wetlands. By holding in floodwaters, they prevent sediment from flowing into the watershed and rebuilding marshes, which are compacting under their own weight and losing ground to sea-level rise.
Shu Yang of the School of Engineering and Applied Science is featured for his research on combining the related structural color and water-repelling properties found in butterfly wings.
PHILADELPHIA — Making uniform coatings is a common engineering challenge, and, when working at the nanoscale, even the tiniest cracks or defects can be a big problem. New research from University of Pennsylvania engineers has shown a new way of avoiding such cracks when depositing thin films of nanoparticles.
