Using a device small enough to fit on the head of a pin, researchers at the University of Illinois at Urbana-Champaign gained new knowledge about the properties of polymer fibers at the nanoscale—knowledge that can inform the design and manufacturing of products made up of random networks of filaments, such as robust filters designed to block foreign particles from entering our lungs.
