Materialism: A Materials Science Podcast
Taylor Sparks and Andrew Falkowski
In this podcast, Taylor and Andrew investigate the past, present, and future of materials science and engineering. Topic areas ranging from cutting edge materials technology, the history of different materials, the commercialization of new materials, and exciting advances in processing and characterization are all covered in detail. Our episodes include things like the unlikely discovery of superglue or teflon, the fascinating backstories about modern biomaterials like dialysis filters, and updates on new technologies including wearable electronics, next generation batteries, and nanomaterials. In short, we hope to help listeners understand the critical role that materials have played in society and even glimpse into what the future may hold for new materials.

Episode 49: μ: Securing Metals Supply
A recent report in the Wall Street Journal pointed out that building one wind turbine requires 900 tons of steel, 2,500 tons of concrete and 45 tons of plastic and a single electric vehicle will require the digging up, moving, and processing of over 500,000 pounds of raw materials! As we transition to electric vehicles and renewable energy and storage we will need to drastically increase the production and availability of metals including lithium, rare-earth elements, nickel, tin, tungsten and more. Where will we find these metals? In this episode we discuss this with Brian Menell, CEO of TechMet Ltd.

Episode 48: Thermal Barrier Coatings
Did you know turbine blades operate in environments above their melting temperature? The secret is a barrier, no thicker than your fingernail, that insulates, protects, and prevents the nickel superalloy blade from melting. In this episode we discuss the materials science that makes low thermal conductivity, high compliance thermal barrier coatings possible. Towards the end we peer into what the future might hold as we push operating temperatures higher.
