The nonstick coating Teflon has saved many hours of scrubbing pots—and maybe a few marriages—and you'll also find it in stents that prop open narrowed blood vessels. For more on Teflon and similar innovations, check out the A to Z of Materials, a free commercial site aimed at engineers and designers interested in “advanced materials,” a category that includes new alloys, ceramics, and composites. Keep up on the latest developments in the field with news updates, a rundown of upcoming conferences, and features on new materials written by experts. The site also profiles thousands of materials, from zirconium-containing alloys that remember their shape to ABS fire retardant, a plastic used in everything from transformers to oven doors. Each entry lists the material's key properties such as density, hardness, and flammability and discusses its advantages and disadvantages.
