18_08b/2008Inside Front Cover: Effects of Laminate Architecture on Fracture Resistance of Sponge Biosilica: Lessons from Nature (Adv. Funct. Mater. 8/2008)

Flexible anchor spicules of Monorhaphis chuni (foreground) consist of thin concentric layers of hydrated silica and proteinaceous material (background). Indentation fracture tests demonstrate that the laminate architecture is responsible for significant enhancements in resistance to crack initiation and subsequent propagation, in work reported by Frank Zok, Dan Morse, and co-workers on p. 1241.
