Scientists have developed a paramagnetic paint that can change color like a football fan changes a T-shirt. It's all part of the amazing world of materials that's covered in three-minute podcasts on "Materials Radio," a new service of ASM International, the materials information society.
"Have a New Car Color Every Day" was written and produced by Andrea Dangelewicz of the Clemson University Materials Advantage Chapter. Here's how the quick-change paint works:
While you drive, pushing a button sends electric current through a special polymer paint containing paramagnetic nanoparticles. The current creates a magnetic field that affects the spacing of crystals within the particles, which changes their ability to reflect light…and voila! A white car becomes Steelers black…or Cardinals red.
Nearly two-dozen podcasts on "Materials Around Us" and "The Science of Materials" are available on Materials Radio to bring the excitement of materials to middle school students, parents and teachers. Visit http://www.materialsradio.com for free downloads.
Materials Radio is an initiative of the K-12 Education Subcommittee of ASM International's Education Committee. "The podcasts come from the most creative minds in our university membership," said K-12 chair Jan Edwards. "Each one was written and recorded by Materials Advantage students who want to share their love of materials with middle school students."
"It's all about making materials science accessible and fun."
ASM International is Everything Material, the Ohio-based society serving the materials science and engineering community. With 36,000 members worldwide. ASM provides authoritative information and knowledge on materials and processes from the structural to the nanoscale. Visit http://www.asminternational.org for details.
