New multilayered materials ready for take off

The video discusses the development of advanced multilayer materials for high-performance applications in extreme environments, such as high temperatures and radiation. Material scientist Trisa Pollack and her team at the University of California, Santa Barbara, in collaboration with GE, are working on creating materials that can withstand these conditions. The video highlights the challenges of making these materials, such as ensuring impermeability to contaminants and enhancing metal substrate strength. Innovations like single crystal growth and advanced modeling tools are explored, along with the use of a custom microscope for detailed material analysis.
