Description: This image shows surface roughness profile of alumina/polymethylmethacrylate (PMMA) hybrid ceramic, created by Berkeley Lab scientists, which mimickes structure of mother of pearl. This ceramic may well be the toughest ceramic ever produced. The roughness of the alumina/PMMA hybrid ceramic controls the strength of the interfaces, which is critical in determining the material’s overall toughness as it affects the sliding process in the polymeric "mortar" layers. Biomimicry - technological innovation inspired by nature – is one of the hottest ideas in science but has yet to yield many practical advances.
