image: Angled view of a material after impact damage. The impact event ejected material from the center of the damage region and created radial cracks around the damage volume. The restorative material is delivered through two isolated fluid streams (dyed red and blue) that infiltrate the cracks and wet the inner surface of the damage. The liquid gels and creates a scaffold for the delivery of new restorative materials and eventual recovery of the entire damage region. This image is after completion of the restoration process. 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
