Ceramics may bring to mind those lopsided pots and lumpy plates children make in grade school. But so-called advanced ceramics show up in everything from armor for military vehicles to bone implants. This site* from the University of Dayton in Ohio can help students and researchers understand how the fine structure of these newfangled ceramics determines their properties. The Digital Library of Ceramic Microstructures houses more than 900 close-ups of materials such as a wadeite crystal from a flat-panel display. The collection also includes examples marred by corrosion, oxidation, or other damaging processes, helping users grasp how the materials wear. A similar library from the University of Cambridge in the U.K. stashes nearly 800 images of ceramics, metals, foams, and other stuff. For materials science teachers, the site also offers a host of lessons and lab exercises.
