image: Angled view of vascular delivery of restorative materials to an open damage volume. Materials are delivered as two isolated fluid streams (dyed red and blue) through a vascular network. They wet the surface of the damage where they quickly gel and act as a scaffold for further deposition and eventual complete damage recovery of lost mass. This image is immediately after starting delivery of fluid streams. This image relates to a paper that appeared in May 9, 2014, issue of Science, published by AAAS. The paper, by Scott White at University of Illinois, Urbana-Champaign in Urbana, Ill., and colleagues was titled, "Restoration of Large Damage Volumes in Polymers." view more
