video: Video of vascular delivery of restorative materials to impact damage in an epoxy sheet, overhead view, at 75x the actual speed. The restorative material begins as a liquid which infiltrates the cracks and wets the inner surface of the damage. The liquid transitions to a gel, which creates a scaffold for the delivery of new restorative materials and eventual recovery of the entire damage region. This video 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
