Materialism: A Materials Science Podcast

• Episode 101: All About Biomatter

  How do we turn plants into plastics and polymers? Find out in this episode as Taylor leaves Utah and ventures to Washington to sit down with Eleftheria Roumeli, an assistant professor at the University of Washington and researcher in the field of biomatter. Learn all about how a fish tank full of "gross" bacteria can be used to create complex and surprisingly strong shapes or about how Eleftheria's research group forages around local shores for seaweed to get the necessary biological materials. Finally we cap it off with a discussion about the environmental impact these materials have and how we should be evaluating their footprint.

• Episode 100: Materials for Bikes

  From antelope skin chains to full beryllium frames its safe to say bikes and the materials that make them have a fascinating history. Join us as we celebrate episode 100 and dive into the materials science behind this beloved mode of transportation. Starting at the invention of the first bike due to a massive volcanic eruption to the specialty bikes more expensive than a car. We break down the materials of the past that have been used to make bikes, such as wood, steel, aluminum, and even bamboo. As well as examining the materials propelling biking into the future such as titanium, carbon fiber, and more, discussing their strengths, weaknesses, and the performance considerations that influence design choices.

• Episode 99: Bulk Metallic Glasses

  How does a metal become a glass? By cooling on the order of 10^6 K/s. We sit down with Jan Schroers, a professor of engineering at Yale to discuss the exciting world of bulk metallic glasses. With over 20 million different combinations these materials are incredibly versatile and have strength numbers on par with ceramics. Also their thermoplastic forming enables metals to be formed into shapes previously thought impossible. These materials truly are a game changer and are definitely worth learning about.

• Episode 98: Accelerating Catalyst Research with Meta

  What brings a social media company into materials science? In this episode, we talk with Larry Zitnick of Meta's Fundamental AI Research (FAIR) and Aaike van Vught from VSParticle about building OCx24, an open catalysis materials database. We discuss the challenges of creating an experimental database from scratch and how autonomous spark ablation devices made it possible. We cap things off with a discussion about how machine learning tools can leverage this database to help us discover new catalysts.

• Episode 97: Titanium

  What do a Mach-3 aircraft and a hip replacement have in common? They are both made of titanium. In this episode we dive into this incredible material from its name rooted in Greek mythology to the unique variants of commercial titanium. Learn about the interesting challenges facing titanium's use in the SR-71 to the new variants being actively researched to help bring this material up to superalloy standards.
