Narrator: This is Science Today. Researchers at the Lawrence Livermore National Laboratory have created thousands of layers of fabricated materials, each about a millimeter thick, known as mutlilayers. Troy Barbee, a material scientist, says multilayer technology may greatly reduce the expensive cost of preventing and repairing corrosive materials.
Barbee: Corrosion costs this country some phenomenal amount of money every year in terms of the degradation of things and failure and the need to do preventive maintenance.
Narrator: A good example of how multilayers may potentially reduce cost would be by replacing the silver components in the Keck Telescope with a more stable material.
Barbee: Silver is notoriously unstable and in fact, if you've ever tried to eat eggs with silverware, you've noticed that it gets black in a hurry. Therefore, let's assume we develop this very stable coating which will not corrode and has high performance. One would put that on the Keck mirrors and that would the only coating you ever put on it. Which is very exciting.
