Broekhuis and colleagues describe development of a new type of thermosetting plastic that can be melted and remolded without losing its original heat-resistance and strength. The scientists showed in laboratory tests that they could melt granules of what they term a "self-healing" polymer and reform them into uniform, rigid plastic bars. They also showed that the plastic could be remolded multiple times, setting the stage for a new generation of recyclable plastics. - MTS

Presto! Fast color-changing material may lead to improved sunglasses
Journal of the American Chemical Society
Researchers in Japan are reporting development of a new so-called "photochromic" material that changes color thousands of times faster than conventional materials when exposed to light. The development could lead to a wide range of new products including improved sunglasses, more powerful computers, dynamic holograms, and better medicines, the researchers say. Their report appears in the Journal of the American Chemical Society, a weekly publication.
